Abstract
Spherical nucleic acids (SNAs) with exceptional colloidal stability, multiple modularity, and programmability are excellent candidates to address common molecular delivery-related issues. Based on this, the higher targeting accuracy and enhanced controllability of stimuli-responsive SNAs render them precise nanoplatforms with inestimable prospects for diverse biomedical applications. Therefore, tailored diagnosis and treatment with stimuli-responsive SNAs may be a robust strategy to break through the bottlenecks associated with traditional nanocarriers. Various stimuli-responsive SNAs are engineered through the incorporation of multifunctional modifications to meet biomedical demands with the development of nucleic acid functionalization. This review provides a comprehensive overview of prominent research in this area and recent advancements in the utilization of stimuli-responsive SNAs in biosensing, bioimaging, and therapeutics. For each aspect, SNA nanoplatforms that exhibit responsive behavior to both internal stimuli (including sequence, enzyme, redox reactions, and pH) and external stimuli (such as light and temperature) are highlighted. This review is expected to offer inspiration and guidance strategies for the rational design and development of stimuli-responsive SNAs in the field of biomedicine.

Abstract
Doxorubicin (DOX) is a clinical chemotherapeutic drug and patients usually suffer from dose-dependent cytotoxic and side effects during chemotherapy process with DOX. Therefore, developing a reliable strategy for DOX analysis in biological samples for dosage guidance during chemotherapy process is of great significance. Herein, a sensitive and selective electrochemical biosensor for DOX detection was designed based on gold nanoparticles (AuNPs) and DNA tetrahedron (TDN) nanoprobe bifunctional glassy carbon electrode that could detect DOX in human serum and cell lysate samples. AuNPs not only could enhance electron transfer efficiency and detection sensitivity, but also could improve the biocompatibility of electrode. TDN nanoprobes were employed as specific DOX bind sites that could bind abundant DOX through intercalative characteristics to contribute to sensitive and selective detection. Under the optimal conditions, the proposed TDN nanoprobes-based DOX biosensor exhibited a wide linear range that ranged from 1.0 nM to 50 μM and a low detection limit that was 0.3 nM. Moreover, the proposed DOX biosensor displayed nice selectivity, reproducibility and stability, and was successfully applied for DOX detection in human serum and cell lysate samples. These promising results maybe pave a way for DOX dosage guidance and therapeutic efficacy optimization in clinic.

Abstract
α-synuclein oligomer is a marker of Parkinson's disease. The traditional enzyme-linked immunosorbent assay for α-synuclein oligomer detection is not conducive to large-scale application due to its time-consuming, high cost and poor stability. Recently, DNA-based biosensors have been increasingly used in the detection of disease markers due to their high sensitivity, simplicity and low cost. In this study, based on the DNAzyme-driven DNA bipedal walking method, we developed a signal-on electrochemical sensor for the detection of α-syn oligomers. Bipedal DNA walkers have a larger walking area and faster walking kinetics, providing higher amplification efficiency compared to conventional DNA walkers. The DNA walker is driven via an Mg2+-dependent DNAzyme, and the binding-induced DNA walker will continuously clamp the MB, resulting in the proliferation of Fc confined near the GE surface. The linear range and limit of detection were 1 fg/mL to 10 pg/mL and 0.57 fg/mL, respectively. The proposed signal-on electrochemical sensing strategy is more selective. It will play a significant role in the sensitive and precise electrochemical analysis of other proteins.

Abstract
Exosomal microRNAs (exomiRNAs) have emerged as promising biomarkers for the early clinical diagnosis of osteoporosis. However, their limited abundance and short length in peripheral blood present significant challenges for the accurate detection of exomiRNAs. Herein, we have designed and implemented an efficacious fluorescence-based biosensor for the highly sensitive detection of exomiRNA associated with osteoporosis, leveraging the enhancing 3D DNA walker-induced CRISPR/Cas12a technology. The engineered DNA walker is capable of efficiently transforming target exomiRNA into amplifying DNA strands, thereby enhancing the sensitivity of the developed biosensor. Concurrently, the liberated DNA strands serve as activators to trigger Cas12a trans-cleavage activity, culminating in a significantly amplified fluorescent signal for the highly sensitive detection of exomiRNA-214. Under optimal conditions, the devised technology demonstrated the capacity to detect target exomiRNA-214 at concentrations as low as 20.42 fM, encompassing a wide linear range extending from 50.0 fM to 10.0 nM. Moreover, the fluorescence-based biosensor could accurately differentiate between healthy individuals and osteoporosis patients via the detection of exomiRNA-214, which was in agreement with RT-qPCR results. As such, this biosensing technology offers promise as a valuable tool for the early diagnosis of osteoporosis.

Abstract
Circulating tumor DNA (ctDNA) is a highly promising biomarker for the early diagnosis and treatment of gastric cancer (GC). However, there is still a lack of effective and practical ctDNA detection methods. In this work, a simple and economical capillary non-gel sieving electrophoresis-LED induced fluorescence detection (NGCE-LEDIF) platform coupled with catalytic hairpin assembly (CHA) as the signal amplification strategy is proposed for quantitative detection of PIK3CA E542K and TP53 (two types of ctDNA associated with GC). We have reasonably designed two pairs of programmable oligonucleotide hairpin probes for PIK3CA E542K and TP53. Using a one-pot reaction, the presence of ctDNA triggers the cyclic amplification of CHA, forming numerous thermodynamically stable H1/H2 double-strands. The H1/H2 double-stranded DNA catalyzed by PIK3CA E542K and TP53 can be easily separated by NGCE due to their different lengths, enabling simultaneous detection of both ctDNAs. Under optimal experimental conditions, the detection limits of this strategy for detecting GC-related biomarkers PIK3CA E542K and TP53 are 20.35 pM and 19.61 pM, respectively, and can achieve 730-fold signal amplification. This strategy has a good recovery in the serum matrix. The results of this study show that this strategy has significant advantages such as high selectivity, a simple process, no special instruments and equipment, no need for fluorescence modification of hairpin probes in advance, high automation, low cost, and minimal sample consumption. This provides a powerful method for the detection of trace cancer biomarkers in the serum matrix with good application prospects.

Abstract
To detect a range of trace biomarkers associated with human diseases, researchers have been focusing on developing biosensors that possess high sensitivity and specificity. Electrochemiluminescence (ECL) biosensors have emerged as a prominent research tool in recent years, owing to their potential superiority in low background signal, high sensitivity, straightforward instrumentation, and ease of operation. Functional nanomaterials (FNMs) exhibit distinct advantages in optimizing electrical conductivity, increasing reaction rate, and expanding specific surface area due to their small size effect, quantum size effect, and surface and interface effects, which can significantly improve the stability, reproducibility, and sensitivity of the biosensors. Thereby, various nanomaterials (NMs) with excellent properties have been developed to construct efficient ECL biosensors. This review provides a detailed summary and discussion of FNMs-based ECL biosensors and their applications in cancer biomarkers detection.

Abstract
Salivary miRNA-31 is a reliable diagnostic marker for early-stage oral squamous cell carcinoma (OSCC), but accurate detection of miRNA-31 in saliva samples is a challenge because of its low level and high sequence homology. The CRISPR/Cas12a system has the exceptional potential to enable simple nucleic acid analysis but suffers from low speed and sensitivity. To achieve rapid and high-sensitive detection of miRNA-31 using the CRISPR/Cas12a system, a Cas12a-based nano-harvester activated by a polymerase-driven DNA walker, named as dual 3D nanorobots, was developed. The target walked rapidly on the surface of DNA hairpin-modified magnetic nanoparticles driven by DNA polymerase, generating numerous double-strand DNA (dsDNA). Then, the Cas12a bound to the generated dsDNA for activating its trans-cleavage activity, forming 3D nano-harvester. Subsequently, the harvester cut and released methylene blue-labeled DNA hairpins immobilized on the sensing interface, leading to the change in electrochemical signal. We found that the trans-cleavage activity of the harvester was higher than the conventional CRISPR/Cas12a system. The developed dual 3D nanorobots could enable rapid (detection time within 60 min), high-sensitive (detection limit of femtomolar), and specific analysis of miRNA-31 in saliva samples. Thus, our established electrochemical biosensing strategy has great potential for early diagnosis of OSCC.

Abstract
With the annual increases in the morbidity and mortality rates of tumors, the use of biomarkers for early diagnosis and real-time monitoring of tumor cells is of great importance. Biomarkers used for tumor cell detection in body fluids include circulating tumor cells, nucleic acids, protein markers, and extracellular vesicles. Among them, circulating tumor cells, circulating tumor DNA, and exosomes have high potential for the prediction, diagnosis, and prognosis of tumor diseases due to the large amount of valuable information on tumor characteristics and evolution; in addition, in situ monitoring of telomerase and miRNA in living cells has been the topic of extensive research to understand tumor development in real time. Various techniques, such as enzyme-linked immunosorbent assays, immunoblotting, and mass spectrometry, have been widely used for the detection of these markers. Among them, the detection of tumor cell markers in body fluids based on electrochemical biosensors and fluorescence signal analysis is highly preferred because of its high sensitivity, rapid detection and portable operation. Herein, we summarize recent research progress in the detection of tumor cell biomarkers in body fluids using electrochemical and fluorescence biosensors, outline the current research status of in situ fluorescence monitoring and the analysis of tumor markers in living cells, and discuss the technical challenges for their practical clinical application to provide a reference for the development of new tumor marker detection methods.

Abstract
Tetrahedral DNA nanostructure (TDN), as a classical bionanomaterial, which not only has excellent structural stability and rigidity, but also possesses high programmability due to strict base-pairs complementation, is widely used in various biosensing and bioanalysis fields. In this study, we first constructed a novel biosensor based on Uracil DNA glycosylase (UDG) -triggered collapse of TDN and terminal deoxynucleotidyl transferase (TDT)-induced insertion of copper nanoparticles (CuNPs) for fluorescence and visual analysis of UDG activity. In the presence of the target enzyme UDG, the uracil base modified on the TDN were specifically identified and removed to produce an abasic site (AP site). Endonuclease IV (Endo.IV) could cleave the AP site, making the TDN collapse and generating 3'-hydroxy (3'-OH), which were then elongated under the assistance of TDT to produce poly (T) sequences. Finally, Copper (II) sulfate (Cu2+) and l-Ascorbic acid (AA) were added to form CuNPs using poly (T) sequences as templates (T-CuNPs), resulting in a strong fluorescence signal. This method exhibited good selectivity and high sensitivity with a detection limit of 8.6 × 10-5 U/mL. Moreover, the strategy has been successfully applied to the screening of UDG inhibitors and the detection of UDG activity in complex cell lysates, which means that it has promising applications in clinical diagnosis and biomedical research.

Abstract
Doxorubicin (DOX) is widely used in chemotherapy as an anti-tumor drug. However, DOX is highly cardio-, neuro- and cytotoxic. For this reason, the continuous monitoring of DOX concentrations in biofluids and tissues is important. Most methods for the determination of DOX concentrations are complex and costly, and are designed to determine pure DOX. The purpose of this work is to demonstrate the capabilities of analytical nanosensors based on the quenching of the fluorescence of alloyed CdZnSeS/ZnS quantum dots (QDs) for operative DOX detection. To maximize the nanosensor quenching efficiency, the spectral features of QDs and DOX were carefully studied, and the complex nature of QD fluorescence quenching in the presence of DOX was shown. Using optimized conditions, turn-off fluorescence nanosensors for direct DOX determination in undiluted human plasma were developed. A DOX concentration of 0.5 µM in plasma was reflected in a decrease in the fluorescence intensity of QDs, stabilized with thioglycolic and 3-mercaptopropionic acids, for 5.8 and 4.4 %, respectively. The calculated Limit of Detection values were 0.08 and 0.03 μg/mL using QDs, stabilized with thioglycolic and 3-mercaptopropionic acids, respectively.

Abstract
Circulating tumor DNA (ctDNA) is regarded as an ideal candidate biomarker for the non-invasive diagnosis of cancer. However, the lack of convenient and reliable detection methods for ctDNA restricts its clinical application. Herein, we developed a dual signal amplification strategy for sensitive detection of ctDNA based on hybridization chain reaction (HCR) and proximity hybridization-regulated CRISPR/Cas12a. The ctDNA initiates HCR through the continuous hybridization of two hairpin probes (H1 and H2), yielding long nicked double-stranded DNA nanowires composed of numerous split segments, which are successively connected to activate the trans-cleavage activity of CRISPR/Cas12a. In this case, the doubly labeled single-stranded DNA reporter can be cleaved to produce a strong fluorescent signal. Owing to the dual amplification of HCR and CRISPR/Cas12a, this strategy exhibits high sensitivity toward ctDNA with a low detection limit of 5.43 fM. Moreover, the proposed method was successfully applied for ctDNA detection in serum samples with satisfactory results, which has great potential in the clinical diagnosis of cancer.

Single-stranded DNA binding protein coupled aptasensor with carbon-gold nanoparticle amplification for marine toxins detection assisted by a miniaturized absorbance reader. JOURNAL OF HAZARDOUS MATERIALS 2023; 450:131023. [PMID: 36857823 DOI: 10.1016/j.jhazmat.2023.131023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 02/10/2023] [Accepted: 02/15/2023] [Indexed: 06/18/2023]
Abstract
Okadaic acid (OA), one of the most widely distributed marine toxins worldwide poses a severe threat to human health. Previous sensing methods for OA detection are usually based on antigen-antibody binding mechanism. However, the drawbacks of antibodies especially the enzyme-labeled antibodies, such as the harsh storage condition and high cost, lead to significant challenges to OA detection in biological samples. To overcome these limitations, a single-stranded DNA binding protein (SSB) coupled aptasensor was developed for OA detection. SSB was incubated on the microplate as a substitute for conventional OA-protein conjugations. Carbon-gold nanoparticles were synthesized and labeled with horseradish peroxidase and thiol-modified aptamers to obtain a capture probe (CGNs@HRP-Apt) instead of the enzyme-labeled antibody for signal amplification. OA and SSB competed to bind with limited aptamers on CGNs@HRP-Apt probes followed by colorimetric assay to obtain the optical signals correlated to OA concentration. To achieve on-site detection, a miniaturized and multichannel absorbance reader (Smart-plate reader) was self-designed with full automation for OA detection. Utilizing the SSB coupled aptasensor and the Smart-plate reader, our approach enables cost-effective and on-site OA sensing with a detection range of 2.5-80 ppb and an ultra-low limit of detection of 0.68 ppb. Moreover, novel OA detection kits based on the SSB coupled aptasensor were prepared which can effectively reduce the cost by 15 times lower than that of commercial ELISA kits. Therefore, the developed platform provides a favorable and promising avenue for marine toxin detection in aquaculture and food safety.

DNAzyme-driven bipedal DNA walker triggered to hybridize silver nanoparticle probes for electrochemical detection of amyloid-β oligomer. Anal Chim Acta 2023; 1246:340889.

Abstract
Amyloid-β oligomer has been considered as a promising molecular biomarker for the diagnosis of Alzheimer's disease due to their significant neural synapse toxicity. Therefore, it is essential to create an easy approach for the selective detection of Amyloid-β oligomer that has high sensitivity and cheap cost. In this work, we developed an innovative enzyme-free electrochemical aptasensor based on the DNAzyme-driven DNA bipedal walker tactics for sensing Amyloid-β oligomer. Bipedal DNA walkers demonstrate a wider walking region, better walking kinetics, and higher amplification effectiveness than typical DNA walkers. The Mg2+-dependent DNAzyme drove the DNA walker, and the binding-induced DNA walker can sequentially shear MBs and form MB fragment structure. Finally, the detection probes modified AgNPs hybridized with the MB fragment structure, resulting in the multiplication of AgNPs on the electrode surface. Electrochemical stripping of AgNPs was used to test the performance of the obtained electrochemical sensor. In particular, a low detection limit of 5.94 fM and a wide linear range of 0.01 pM-0.1 nM were attained. The detection of Amyloid-β oligomer in human serum was then carried out using this bipedal DNA walker biosensor, which shown good selectivity and outstanding reproducibility, indicating its usefulness in bioanalysis.

Abstract
A dual-mode biosensor constructed based on photoelectrochemical (PEC) and electrochemical (EC) property was developed for assaying circulating tumor DNA (ctDNA), which is commonly used for triple-negative breast cancer diagnosis. Ionic liquid functionalized two-dimensional Nd-MOF nanosheets were successfully synthesized through a template-assisted reagent substituting reaction. Nd-MOF nanosheets integrated with gold nanoparticles (AuNPs) were able to improve photocurrent response and supply active sites for assembling sensing elements. To achieve selective detection of ctDNA, thiol-functionalized capture probes (CPs) were immobilized on the Nd-MOF@AuNPs modified glassy carbon electrode surface, thereby generating a "signal-off" photoelectrochemical biosensor for ctDNA under visible light irradiation. After the recognition of ctDNA, ferrocene-labeled signaling probes (Fc-SPs) were introduced into the biosensing interface. After hybridization between ctDNA and Fc-SPs, the oxidation peak current of Fc-SPs generated from square wave voltammetry can be employed as a "signal-on" electrochemical signal for ctDNA quantification. Under the optimized conditions, a linear relationship was obtained to the logarithm of ctDNA concentration in between 1.0 fmol L-1 to 10 nmol L-1 for the PEC model and 1.0 fmol L-1 to 1.0 nmol L-1 for the EC model. The dual-mode biosensor can provide accurate results for ctDNA assays, effectively eliminating the probable occurrence of false-positive or false-negative results in single-model assays. By switching DNA probe sequences, the proposed dual-mode biosensing platform can serve as a strategy for detecting other DNAs and possesses broad applications in bioassay and early disease diagnosis.

Abstract
Technologies for quantifying circulating tumour DNA (ctDNA) in liquid biopsies could enable real-time measurements of cancer progression, profoundly impacting patient care. Sequencing methods can be too complex and time-consuming for regular point-of-care monitoring, but nanotechnology offers an alternative, harnessing the unique properties of objects tens to hundreds of nanometres in size. This systematic review was performed to identify all examples of nanotechnology-based ctDNA detection and assess their potential for clinical use. Google Scholar, PubMed, Web of Science, Google Patents, Espacenet and Embase/MEDLINE were searched up to 23rd March 2021. The review identified nanotechnology-based methods for ctDNA detection for which quantitative measures (e.g., limit of detection, LOD) were reported and biologically relevant samples were used. The pre-defined inclusion criteria were met by 66 records. LODs ranged from 10 zM to 50nM. 25 records presented an LOD of 10fM or below. Nanotechnology-based approaches could provide the basis for the next wave of advances in ctDNA diagnostics, enabling analysis at the point-of-care, but none are currently used clinically. Further work is needed in development and validation; trade-offs are expected between different performance measures e.g., number of sequences detected and time to result.

Abstract
An electrochemical-DNA (E-DNA) sensor was constructed by using DNA metallization to produce an electrochemical signal reporter in situ and hybridization chain reaction (HCR) as signal amplification strategy. The cyclic voltammetry (CV) technique was used to characterize the electrochemical solid-state Ag/AgCl process. Moreover, the enzyme cleavage technique was introduced to reduce background signals and further improve recognition accuracy. On the basis of these techniques, the as-prepared E-DNA sensor exhibited superior sensing performance for trace ctDNA analysis with a detection range of 0.5 fM to 10 pM and a detection limit of 7 aM. The proposed E-DNA sensor also displayed excellent selectivity, satisfied repeatability and stability, and had good recovery, all of which supports its potential applications for future clinical sample analysis.

Abstract
DNA walker machines, as one of the dynamic DNA nanodevices, have attracted extensive interest in the field of analysis due to their inherent superiority. Herein, we reported a split aptamer remodeling-initiated target-self-service 3D-DNA walker for ultrasensitive, specific, and high-signal-background ratio determination of 17β-estradiol (E2) in food samples. Two split probes (STWS-a and STWS-b) were rationally designed that can undergo structural reassembled to serve as walking strands (STWS) under the induction of the target. Meanwhile, an intact E6-DNAzyme region was formed and activated at the tail of STWS. The activated E6-DNAzyme then continuously drives the 3D-DNA walker for signal amplification and specific detection of E2. Under optimal conditions, the proposed DNA walker-based biosensor exhibited excellent linearity in the range of 1 pM to 50 nM with a low limit of detection (LOD) of 0.28 pM, and good precision (2.7%) for 11 replicate determinations of 1 nM of E2. Furthermore, the developed DNA walker-based biosensor achieved excellent sensitive analysis of E2 in the complex food matrix with recoveries of 95.6-106.5%. This newly proposed split aptamer-based strategy has the advantages of ultrasensitive, high signal-to-background ratio, and high stability. Noteworthy, the successful operation of the DNA walker initiated by the split aptamer expands the principles of DNA walker design and provides a universal signal amplification platform for trace analysis.

Abstract
An ultrasensitive electrochemical biosensor was designed for the rapid label-free detection of circulating tumor DNA (ctDNA, EGFR 19 Dels for non-small cell lung cancer, NSCLC). We linked the highly conjugated tricatecholate, 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) with Ni(II) ions into the two-dimensional porous conductive metal-organic frameworks (MOFs), which is termed Ni-catecholates (Ni-CAT). Then, the AuNPs/Ni-catecholates/carbon black/polarized pencil graphite electrode (AuNPs/Ni-CAT/CB/PPGE) was obtained by electrodeposition of AuNPs on the surface of PPGE modified with Ni-CAT/CB composite materials. The AuNPs/Ni-CAT/CB/PPGE were used for label-less detection of ctDNA, with a total detection time of only 30 min. Under optimal detection conditions, the AuNPs/Ni-CAT/CB/PPGE sensor exhibited excellent detection performance with good linear response to ctDNA over a wide concentration range and the detection limit down to the femtomolar level. The sensor was applied to the determination of ctDNA in serum samples with high sensitivity. This simple, efficient, and expeditious method has practical value in liquid biopsy of ctDNA and has potential for development in early detection, treatment, and prognosis of tumors. Herein, an ultrasensitive electrochemical biosensor was designed for the rapid label-free detection of ctDNA (EGFR 19 Dels for non-small cell lung cancer, NSCLC). We linked the highly conjugated tricatecholate, 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) with Ni(II) ions into the two-dimensional porous conductive metal-organic frameworks (MOFs), which is termed as Ni-catecholates (Ni-CAT). Then, the AuNPs/Ni-catecholates/carbon black/polarized pencil graphite electrode (AuNPs/Ni-CAT/CB/PPGE) was obtained by electrodeposition of AuNPs on the surface of PPGE modified with Ni-CAT/CB composite materials. The AuNPs/Ni-CAT/CB/PPGEs were used for label-less detection of ctDNA, with a total detection time of only 30 min. Under optimal detection conditions, the AuNPs/Ni-CAT/CB/PPGE sensor exhibited excellent detection performance with good linear response to ctDNA in the concentration range of 1 × 10-15 M to 1 × 10-6 M and with a detection limit as low as 0.32 fM. The sensor was applied for determination of ctDNA in serum samples and gave high sensitivity. This simple, efficient and expeditious method has practical value in liquid biopsy of ctDNA and has potential for development in early detection, treatment and prognosis of tumors.

Abstract
Early and accurate diagnosis of SARS-CoV-2 was crucial for COVID-19 control and urgently required ultra-sensitive and rapid detection methods. CRISPR-based detection systems have great potential for rapid SARS-CoV-2 detection, but detecting ultra-low viral loads remains technically challenging. Here, we report an ultrasensitive CRISPR/Cas12a-based electrochemical detection system with an electrochemical biosensor, dubbed CRISPR-SPCE, in which the CRISPR ssDNA reporter was immobilized onto a screen-printed carbon electrode. Electrochemical signals are detected due to CRISPR cleavage, giving enhanced detection sensitivity. CRISPR-SPCE enables ultrasensitive SARS-CoV-2 detection, reaching as few as 0.27 copies μL-1. Moreover, CRISPR-SPCE is also highly specific and inexpensive, providing a fast and simple SARS-CoV-2 assay.

Abstract
Electrochemical methodology has probably been the most used sensing platform in the past few years as they provide superior advantages. In particular, screen-printed electrode (SPE)-based sensing applications stand out as they provide extraordinary miniaturized but robust and user-friendly detection system. In this context, we are focusing on the modification of SPE with functional nucleic acid probes and nanostructures to improve the electrochemical detection performance in versatile sensing applications, particularly in the fight against the COVID-19 pandemic. Aptamers are immobilized on the electrode surface to detect non-nucleic acid targets and complementary probes to recognize and capture nucleic acid targets. In a step further, SPE-based biosensors with the modification of self-assembled DNA nanostructures are emphasized as they offer great potential for the interface engineering of the electrode surface and promote the excellent performance of various interface reactions. By equipping with a portable potentiostat and a smartphone monitoring device, the realization of this SPE-based miniaturized diagnostic system for the further requirement of fast and POC detection is revealed. Finally, more novel and excellent works are previewed and future perspectives in this field are mentioned.

Abstract
Considerable advances have been made in the design, modularization, functionalization, and regulation of DNA nanostructures over the past 40 years. These advances have accelerated the development of DNA nanomachines such as DNA walkers, dynamic nanomachines with walking feet, tracks, and driven forces, which have highly sensitive detection and signal amplification abilities that can be applied to various bioanalytical contexts and therapeutic strategies. Here, we describe a rational design of the nano-bio interface, the kinetics of DNA walkers and the strategies for improving their efficiency and sensitivity. We also outline the various bioanalytic and imaging applications to which DNA walkers have been applied, such as electrochemical and optical measurements, when integrated with other simulation and activation tools. Finally, we compare the performances of novel DNA walker-based strategies for bioanalysis and propose a method to improve DNA walker design.

Abstract
A flap endonuclease 1 (FEN 1)-assisted swing arm DNA walker was constructed to achieve the signal amplification detection of ctDNA. The MB-labeled hairpin DNA was designed as the track and a long swing-arm DNA strand as the capture probe. The introduction of ctDNA unlocked a helper hairpin DNA, which could be captured to form the DNA duplex walker with the capture probe, and also activated the catalyst hairpin assembly. The DNA duplex walker opened the hairpin track and formed a three-base overlapping DNA structure, which was recognized and cleaved by FEN 1. Driven by the FEN 1 and the high reaction temperature, the DNA walker was initiated to hybridize with the track DNA and release multiple MB-labeled flaps for signal amplification. Owing to the excellent amplification capacity of the target recycling-induced DNA walker and programmed catalysis hairpin assembly, the one-step biosensor showed a linear detection range from 1 fM to 100 pM with a detection limit of 0.33 fM. Moreover, the sensitive detection of ctDNA in serum samples was verified, suggesting its potential application in liquid biopsy for clinical diagnosis.

Abstract
Adopting carbon nanotube (CNT) transistors as biosensors has been developed as a promising method for cancer biomarker detection, which has shown superior sensitivity and selectivity. However, the detection of circulating tumor DNA (ctDNA) by the CNT transistor based biosensors is still a challenge and no work has been reported. Here, direct label-free DNA detection of AKT2 gene related to triple-negative breast cancer by all-CNT thin-film transistor (TFT) biosensors incorporated with tetrahedral DNA nanostructures (TDNs) is proposed and achieved for the first time. The adoption of TDNs enables improved biosensor response for at least 35% and even as high as 98% as compared with single-stranded DNA (ssDNA) probes owing to the enhanced DNA hybridization efficiency. Influence of the TDNs' linker length on the biosensor performance is important and has been investigated. Concentration-dependent DNA detection is achieved by the all-CNT TFT biosensors with a broad linear detection range of six orders of magnitude and a theoretical limit of detection (LOD) of 2 fM. In addition, the all-CNT TFT biosensors exhibit favorable selectivity and repeatability. The platform of all-CNT TFT biosensors incorporated with TDNs has great potential for multiplexed detection of various cancer biomarkers, providing a simple yet high performance universal strategy for low-cost clinical applications.

Abstract
Diseases caused by bacteria pose great challenges to human health. The key to reduce disease transmission and mortality is to develop accurate and rapid methods for the detection and identification of bacteria. Herein, a rapid bacteria 16S rDNA electrochemical sensor based on target-triggered hairpin self-assembly and tripedal DNA walker (TD walker) amplification strategy was constructed. Specific variable region of 16S rDNA fragment of bacteria was used as biomarker. The target-triggered hairpin self-assembly strategy was used to prepare a TD walker. The hairpin DNA probes labeled with ferrocene (Fc) were designed and modified on surface of electrode. The "legs" of TD walker hybridized with three hairpin probes and opened their hairpin structures. Exo III enzyme recognised hybrid duplexes and selectively digest hairpin probes. The "legs" of TD walker was released and hybridized with the other three hairpin probes. In this way, the enzyme drived the walkers to walk along electrode interface, until hairpin DNA probes were all removed from the electrode, the Fc was far away from electrode interface. A significantly current reduction signal was obtained and bacteria were detected by recording this response. This strategy was low-cost and scalable, it could continuously recycle low-concentration targets, thus enhanced the detection sensitivity. As the proof-of-concept work, the electrochemical sensor was utilized as detector. The limit of detection (LOD) of detecting Staphylococcus aureus (S. aureus) was 20 CFU mL-1 and detection time was less than 3 h. It was expected to be widely used in clinical early diagnosis.

Abstract
The binding between anticancer drugs and double-stranded DNA (dsDNA) is a key issue to understand their mechanism of action, and many chemical methods have been explored on this task. Molecular docking techniques successfully predict the affinity of small molecules into the DNA binding sites. In turn, various DNA-targeted drugs are electroactive; in this regard, their electrochemical behavior may change according to the nature and strength of interaction with DNA. A carbon paste electrode (CPE) modified with calf thymus ds-DNA (CPDE) and computational methods were used to evaluate the drug–DNA intercalation of doxorubicin (DOX), daunorubicin (DAU), idarubicin (IDA), dacarbazine (DAR), mitoxantrone (MIT), and methotrexate (MTX), aiming to evaluate eventual correlations. CPE and CPDE were immersed in pH 7 0.1 mM solutions of each drug with different incubation times. As expected, the CPDE response for all DNA-targeted drugs was higher than that of CPE, evidencing the drug–DNA interaction. A peak current increase of up to 10-fold was observed; the lowest increase was seen for MTX, and the highest increase for MIT. Although this increase in the sensitivity is certainly tied to preconcentration effects of DNA, the data did not agree entirely with docking studies, evidencing the participation of other factors, such as viscosity, interfacial electrostatic interactions, and coefficient of diffusion.

Abstract
The accurate assay of cardiac troponin I (cTnI) is very important for acute myocardial infarction (AMI), it also can be employed as an effective index for screening serious patients in COVID-19 pandemic before fatal heart injury to reduce the mortality. A ratiometric sensing strategy was proposed based on electrochemiluminescent (ECL) signal of doxorubicin (Dox)-luminol or the electrochemical (EC) signal of methylene blue (MB) vs. referable EC signal of Dox. The bio-recognitive Tro4-aptamer ensures the high specificity of the sensor by affinity binding to catch cTnI, and the tetrahedral DNA (TDs) on Au/Ti3C2-MXene built an excellent sensing matrix. An in situ hybrid chain reaction (HCR) amplification greatly improved the sensitivity. The ratiometric sensing responses ECLDox-luminol/CurrentDox or CurrentMB/CurrentDox linearly regressed to cTnI concentration in the range of 0.1 fM-1 pM or 0.1 fM-500 fM with the limit of detection (LOD) as 0.04 fM or 0.1 fM, respectively. Served as the reference signal, CurrentDox reflected the variation of sensor, it is very effective to ensure the accuracy of detection to obviate the false results. The proposed biosensors show good specificity, sensitivity, reproducibility and stability, have been applied to determine cTnI in real samples with satisfactory results. They are worth looking forward to be used for screening serious patient of COVID-19 to reduce the mortality, especially in mobile cabin hospital.

Abstract
In this work, a DNA three-way junction (TWJ) with multiple recognition regions was intelligently engineered, which could be applied as an unconfined DNA walker with a rapid walking speed and high sensitivity for electrochemical detection of microRNA (miRNA-182-5p). Once the target miRNA was presented, the hairpins on TWJ could be successively opened to form an annular DNA walker, which could walk on the entire scope of the electrode surface without the confine for the length of DNA walker legs compared with the traditional DNA walker, greatly improving the walking efficiency. In addition, this DNA walker with multirecognition segments could obviously increase the local concentration of recognition sites, which significantly enhanced the detection speed and sensitivity. As a result, this proposed biosensor with annular DNA as a walker could dexterously achieve the ultrasensitive and fast detection of miRNA-182-5p from 0.1 fM to 1 nM with a detection limit of 31.13 aM. Meaningfully, this strategy explored an innovative path in the design of a new DNA walker nanostructure for accomplishing speedy and sensitive detection of biomarkers.

Yang X, Liao M, Zhang H, Gong J, Yang F, Xu M, Tremblay PL, Zhang T. An electrochemiluminescence resonance energy transfer biosensor for the detection of circulating tumor DNA from blood plasma. iScience 2021; 24:103019. [PMID: 34522862 PMCID: PMC8426273 DOI: 10.1016/j.isci.2021.103019] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 08/02/2021] [Accepted: 08/18/2021] [Indexed: 01/14/2023] Open
Abstract
A liquid biopsy is a noninvasive approach for detecting double-stranded circulating tumor DNA (ctDNA) of 90-320 nucleotides in blood plasma from patients with cancer. Most techniques employed for ctDNA detection are time consuming and require expensive DNA purification kits. Electrochemiluminescence resonance energy transfer (ECL-RET) biosensors exhibit high sensitivity, a wide response range, and are promising for straightforward sensing applications. Until now, ECL-RET biosensors have been designed for sensing short single-stranded oligonucleotides of less than 45 nucleotides. In this work, an ECL-RET biosensor comprising graphitic carbon nitride quantum dots was assessed for the amplification-free detection in the blood plasma of DNA molecules coding for the EGFR L858R mutation, which is associated with non-small-cell lung cancer. Following a low-cost pre-treatment, the highly specific ECL-RET biosensor quantified double-stranded EGFR L858R DNA of 159 nucleotides diluted into the blood within a linear range of 0.01 fM to 1 pM, demonstrating its potential for noninvasive biopsies.

Abstract
In view of the urgent need to determine polychlorinated biphenyls (PCBs) in the environment, we report a simple and sensitive electrochemical aptasensor to detect 3,3',4,4'-tetrachlorobiphenyl (PCB77) based on Exonuclease III-powered Deoxyribonucleic Acid (DNA) walking machine using poly (diallyldimethylammonium chloride) (PDDA), which was functionalized hollow porous graphitic carbon nitride/ Ni-Co hollow nanoboxes/ Au-Pd-Pt nanoflowers composite material. Upon the addition of PCB77, the specific binding between PCB77 and the aptamer (Apt) could trigger the Exo III-assisted cyclic amplification process and release unlocking probes to deblock the Swing arm/Blocker duplex. Finally, the hybridized hairpin 3 (HP3), a short oligonucleotide, was left on the electrode via Exo III digestion of hybridized HP2, and thus a strong methylene blue (MB) signal was obtained. As expected, the proposed aptasensor exhibits exceptional PCB77 detection performances with a very low detection limit of 5.13 pg/L and a wide linear range of 0.01-100 ng/L based on the calibration curve. Moreover, the aptasensor presents a high level of selectivity and stability, with an acceptable degree of reproducibility. The results of this study have indicated that the proposed aptasensor has great potential application prospects, as demonstrated by its successful use in real environmental water samples.

Abstract
Nucleic acids, including DNA and RNA, have received prodigious attention as potential biomarkers for precise and early diagnosis of cancers. However, due to their small quantity and instability in body fluids, precise and sensitive detection is highly important. Taking advantage of the ease-to-functionality and plasmonic effect of nanomaterials, fluorescence resonance energy transfer (FRET) and metal-enhanced fluorescence (MEF)-based biosensors have been developed for accurate and sensitive quantitation of cancer-related nucleic acids. This review summarizes the recent strategies and advances in recently developed nanomaterial-based FRET and MEF for biosensors for the detection of nucleic acids in cancer diagnosis. Challenges and opportunities in this field are also discussed. We anticipate that the FRET and MEF-based biosensors discussed in this review will provide valuable information for the sensitive detection of nucleic acids and early diagnosis of cancers.

An "off-on" electrochemiluminescence biosensor coupled with strand displacement-powered 3D micromolecule walking nanomachine for ultrasensitive detection of adenosine triphosphate.

Abstract
A three-dimensional (3D) micromolecule walking nanomachine propelled by strand displacement was developed to establish a novel switching electrochemiluminescence (ECL) biosensor for ultrasensitive detection of adenosine triphosphate (ATP). Generally, walking nanomachines reported previously were limited to DNA walkers, while the proposed 3D walking nanomachine focused on the micromolecule walker. Firstly, TiO2 and silver nanoparticles (Ag NPs) functionalized N-(4-aminobutyl)-N-(ethylisoluminol) (Ag-ABEI) were deposited onto the electrode surface to offer an enhanced ECL signal, resulting from the double catalytic effect of TiO2 and Ag NPs for H2O2. Following, dopamine (DA)-labeled DNA duplex probes (S1/S2-DA) immobilized onto the modified electrode cut down the original ECL signal due to the quenching of DA toward ABEI (signal-off). Target ATP walker moved along the 3D DNA track, simultaneously releasing numerous DNA3, which was applied to displace S2-DA, resulting in the quenched ECL intensity recovery (signal-on). As a result, the biosensor showed a low limit of detection down to 0.5 nM (S/N = 3) and was successfully employed to determine ATP in human serum samples. Thus, the established biosensing strategy holds great potential for biochemical studies and clinical diagnosis.

Abstract
In this study, a ternary electrochemiluminescence (ECL) sensing platform coupled with a multiple signal amplification strategy was proposed for ultrasensitive detection of miRNA-141. The initial signal amplification was achieved via three-dimensional reduced graphene oxide (3D-rGO)@Au nanoparticles (NPs) to form an excellent conductive layer. Then, AuPd NPs as a coreaction accelerator was introduced into the N-(4-aminobutyl)-N-(ethylisoluminol) (ABEI)-H2O2 system to facilitate the transformation from H2O2 to excess superoxide anion radicals (O2•-), which further amplified the ECL emission of ABEI, leading to a significant increase of the ECL signal. Meanwhile, in the presence of miRNA-141 and T7 Exonuclease (T7 Exo), the self-assembled DNA swing arm can be driven to walk autonomously. The DNA walker reaction could result in the release of numerous labeled luminophores, which could react to achieve an extremely weak ECL signal. Surprisingly, the established ECL sensor platform for the detection of miRNA-141 demonstrated excellent sensitivity with a low detection limit of 31.9 aM in the concentration range from 100 aM to 1 nM. Consequently, the designed strategy greatly improves the luminous efficiency of the ternary ECL system and provides a special approach for the detection of nucleic acids and biomarkers in clinical and biochemical analysis.

Abstract
MicroRNAs (miRNAs) have been accepted as promising non-invasive biomarkers for cancer early diagnosis. Developing amplified sensing strategies for detecting ultralow concentration of miRNAs in clinical samples still requires much effort. Herein, an integrated fluorescence biosensor using nicking enzyme-powered numerous-feet DNA walking machine was developed for ultrasensitive detection of miRNA. A long numerous-feet walker produced by target-triggered rolling circle amplification autonomously moves along the defined DNA tracks on gold nanorods (AuNRs) with the help of nicking enzyme, leading to the recovery of fluorescence. This results in an amplified fluorescence signal, typically measured at 518 nm emission wavelength. Benefiting from the long walker that dramatically improves movement range, the homogenous and one-step strategy realizes ultrahigh sensitivity with a limit of detection of 0.8 fM. Furthermore, this walking machine has been successfully used to quantification of miRNA in clinical serum samples. The consistency of the gained results between of the developed strategy and reverse transcription quantitative polymerase chain reaction (RT-qPCR) shows that the sensing method has great promise for tumor diagnostics based on nucleic acid. Schematic representation of the fluorescent biosensing strategy, numerous-legged DNA walker prepared by rolling circle amplification on gold nanorods (AuNRs) for microRNA analysis, which can be applied in real samples with good results.

Abstract
The detection of circulating tumor DNA (ctDNA) has increasingly received a great deal of attention considering its significance in cancer diagnosis. And the signal amplification plays an important role in the development of sensitive ctDNA biosensors. Herein, the nanocomposites (denoted as HAC-AuPt), integrating from high-active carbon (HAC) and AuPt alloy nanoparticles, were synthesized and subsequently used as a signal amplification label to fabricate a sandwich-type ctDNA electrochemical biosensor. Characterizations demonstrated that HAC presents uniform size distribution and AuPt alloy nanoparticles were successfully loaded on HAC. The current response could be amplified to a great extent by the resultant HAC-AuPt due to its excellent electrochemical property. The nanocomposites were further bounded with DNA signal probes (SPs) via Au-S or Pt-S assembly to form SPs-label. After the capture probes (CPs) were immobilized on the electrode surface, the target DNA (tDNA) and SPs-label were stepwise incubated on the CPs-modified electrode, thus forming a sandwich-type structure. By monitoring the catalytic signal of HAC-AuPt towards the reduction process of H2O2, this biosensor provided a wide linear range of 10-8 mol/L - 10-16 mol/L with a low detection limit of 3.6 × 10-17 mol/L (S/N = 3) for the detection of the tDNA. Furthermore, obvious differences in response signals among different DNAs were observed benefitting from the excellent selectivity of the biosensor. Besides, the long-term stability, reproducibility, and recovery rate were proved to be outstanding. These results indicate that the established biosensor holds a potential application in the clinical diagnosis of ctDNA.

Abstract
Low abundance gene-PIK3CAH1047R mutation detection is crucial for the clinical diagnosis and treatment of breast cancer. Here, a fluorescent biosensor which combines cascaded strand displacement amplification (C-SDA) and trans-cleavage ability of CRISPR/Cas12a was established to ultra-sensitively detect gene-PIK3CAH1047R mutation. The mutated gene-PIK3CAH1047R can combine with complementary sequence to form an intact recognition site for endonuclease FspI. Mediated by FspI, it breaks at the mutation site to produce DNA fragment to trigger SDA or C-SDA. Then, the fluorescent biosensors based on SDA-CRISPR/Cas12a or C-SDA-CRISPR/Cas12a were constructed. Compared with biosensor based on SDA-CRISPR/Cas12a (5 pM), the minimum detection of the biosensor based on C-SDA-CRISPR/Cas12a is reduced two orders of magnitude (50 fM). In range of 0.001%-50%, we achieved the ultrasensitive detection of gene-PIK3CAH1047R mutation low to 0.001%. Besides, the proposed biosensor works well in human serum samples, showing its application potential in low-abundance gene-PIK3CAH1047R mutation detection.

Liquid biopsy genotyping by a simple lateral flow strip assay with visual detection. Anal Chim Acta 2021; 1163:338470.

Abstract
Liquid biopsy, as a minimally invasive method that allows real-time monitoring of the tumor genome, represents a competing approach for cancer diagnosis, prognosis and therapy decision making. Liquid biopsy in cancer patients mainly includes analysis of circulating tumor cells (CTC) and cell-free circulating tumor DNA (ctDNA). ctDNA is the tumor-derived fraction of the cell-free DNA present in the blood. ctDNA is detected based on cancer-specific genomic aberrations (mainly mutations) and represents a challenging analyte due to high fragmentation and low concentration. Several methodologies have been developed for ctDNA analysis in cancer patients but many of these technologies are too time-intensive, complicated and expensive for implementation in diagnostic testing. Herein, we developed a novel lateral flow strip assay for mutational analysis of ctDNA in blood samples and visual detection that is based on gold nanoparticles as reporters. As a model, common single-point mutations of the KRAS gene, related to colorectal cancer (CRC), have been selected for method development. The proposed DNA biosensor has been successfully applied for the detection of three KRAS mutations (KRAS G12D/A/V), along with the wild-type KRAS gene in synthetic DNA targets, cancer cell lines and cfDNA from blood samples of healthy individuals and CRC patients. The main advantages of the proposed lateral flow assay are simplicity, rapid analysis time (∼10 min) and visual detection without the requirement of special instrumentation. The assay is also cost-effective with high detectability, specificity and reproducibility and has the potential to be used as a portable and universal device. In conclusion, the proposed assay offers a rapid diagnostic strip test for visual genotyping, as an alternative approach for liquid biopsy applications.

Abstract
An accurate and robust method for quantifying the levels of circulating tumor DNA (ctDNA) is vital if this potential biomarker is to be used for the early diagnosis of cancer. The analysis of ctDNA presents unique challenges because of its short half-life and ultralow abundance in early stage cancers. Here we develop an ultrasensitive electrochemical biosensor for rapid detection of ctDNA in whole blood. The sensing of ctDNA is based on hybridization on a network of probe DNA modified gold-coated magnetic nanoparticles (DNA-Au@MNPs). This DNA-Au@MNPs biosensor can selectively detect short- and long-strand DNA targets. It has a broad dynamic range (2 aM to 20 nM) for 22 nucleotide DNA target with an ultralow detection limit of 3.3 aM. For 101 nucleotide ctDNA target, a dynamic range from 200 aM to 20 nM was achieved with a detection limit of 5 fM. This DNA-Au@MNPs based sensor provides a promising method to achieve 20 min response time and minimally invasive cancer early diagnosis.

Abstract
Tumor is a kind of abnormal organism generated by the proliferation and differentiation of cells in the body under the action of various initiating and promoting factors, which seriously threatens human life and health. Tumorigenesis is a gradual process that involves multistage reactions and the accumulation of mutations. Gene mutation usually occurs during tumorigenesis, and can be used for tumor diagnosis. Early diagnosis is the most effective way to improve the cure rate and reduce the mortality rate. Among the peripheral blood circulating tumor DNA (ctDNA), gene mutation in keeping with tumor cells can be detected, which can potentially replace tumor tissue section for early diagnosis. It has been considered as a liquid biopsy marker with good clinical application prospect. However, the high fragmentation and low concentration of ctDNA in blood result in the difficulty of tumor stage determination. Therefore, high sensitive and specific mutation detection methods have been developed to detect trace mutant ctDNA. At present, the approaches include digital PCR (dPCR), Bead, Emulsion, Amplification and Magnetic (BEAMing), Next Generation Sequencing (NGS), Amplification Refractory Mutation System (ARMS), etc. In this paper, the principle, characteristics, latest progress and application prospects of these methods are reviewed, which will facilitate researchers to choose appropriate ctDNA detection approaches.

Abstract
In contrast to common DNA walkers, multipedal DNA walkers exhibit larger walking area and faster walking kinetics and provide increased amplification efficiency. Consequently, they have received a considerable amount of attention in biosensing. However, most of them are synthesized by immobilizing multiple DNA walking strands on the surface of Au nanoparticles, which is tedious and time-consuming. Simple preparation of multipedal DNA walkers remains a challenge. Herein, we adopted a simple enzyme-free target-triggered catalytic hairpin assembly (CHA) circuit to synthesize a tripedal DNA walker. By walking on a DNA track-functionalized electrode, a sensitive electrochemiluminescence DNA nanomachine biosensor was constructed for sensing miRNA-21. The DNA walker was powered by toehold-mediated strand displacement; the whole process did not need the assistance of enzymes, thus avoiding tedious procedures and enzyme degradation under unfavorable environmental conditions. Specifically, a superior detection limit of 4 aM and a broad linear range of 10 aM to 1 pM were achieved. This CHA-tripedal DNA walker biosensor was then applied for the detection of miRNA-21 in human serum and showed high selectivity and excellent reproducibility, demonstrating its practical application in bioanalysis. In particular, the Y-shaped tripedal DNA walker comes from the DNA circuit, which makes the approach ideally suited for biosensing of small nucleic acid targets.

Abstract
DNA walkers, as intelligent artificial DNA nanomachines, have been widely used as efficient nucleic acid amplification tools that the detection sensitivity can be improved by incorporating DNA walkers into DNA biosensors. Nevertheless, since the premature release or flameout in a region of locally exhausted substrate, the walking efficiency of DNA walkers remains unsatisfactory. In this work, we design a smart tripedal DNA walker that is formed by target-initiated catalyzed hairpin assembly (CHA), which can move along the DNA duplex tracks on electrode driven by toehold-mediated DNA strand displacement (TMSD) for transduction and amplification of electrochemical signals. Emphatically, this flexible tripedal DNA walker is capable of walking freely along the tracks with unconstrained walking range. Moreover, the design of multi-legged walker can weaken the derailment of leg DNA and shorten the moving time on electrode, ensuring the processive walking with high efficiency. Additionally, the persistent walking of tripedal walker is driven by cascading TMSD, which eliminates the defects of high cost and instability of enzyme-assisted amplification technology. Therefore, the tripedal DNA walker-based electrochemical biosensor has enormous potential for the applications of OTA detection, and reveals a new avenue for food safety analysis and clinical diagnosis.
