Abstract
Aptamers are promising biorecognition elements for sensors. However, aptamer-based assays often lack the requisite levels of sensitivity and/or selectivity because they typically employ structure-switching aptamers with attenuated affinity and/or utilize reporters that require aptamer labeling or which are susceptible to false positives. Dye-displacement assays offer a label-free, sensitive means for overcoming these issues, wherein target binding liberates a dye that is complexed with the aptamer, producing an optical readout. However, broad utilization of these assays has been limited. Here, we demonstrate a rational approach to develop colorimetric cyanine dye-displacement assays that can be broadly applied to DNA aptamers regardless of their structure, sequence, affinity, or the physicochemical properties of their targets. Our approach should accelerate the development of mix-and-measure assays that could be applied for diverse analytical applications.

Abstract
Transient, dissipative, aggregation and deaggregation of Au nanoparticles (NPs) or semiconductor quantum dots (QDs) leading to control over their transient optical properties are introduced. The systems consist of nucleic acid-modified pairs of Au NPs or pairs of CdSe/ZnS QDs, an auxiliary duplex L1/T1, and the nicking enzyme Nt.BbvCI as functional modules yielding transient aggregation/deaggregation of the NPs and dynamically controlling over their optical properties. In the presence of a fuel strand L1', the duplex L1/T1 is separated, leading to the release of T1 and the formation of duplex L1/L1'. The released T1 leads to aggregation of the Au NPs or to the T1-induced G-quadruplex bridged aggregated CdSe/ZnS QDs. Biocatalytic nicking of the L1/L1' duplex fragments L1' and the released L1 displaces T1 bridging the aggregated NPs or QDs, resulting in the dynamic recovery of the original NPs or QDs modules. The dynamic aggregation/deaggregation of the Au NPs is followed by the transient interparticle plasmon coupling spectral changes. The dynamic aggregation/deaggregation of the CdSe/ZnS QDs is probed by following the transient chemiluminescence generated by the hemin/G-quadruplexes bridging the QDs and by the accompanying transient chemiluminescence resonance energy transfer proceeding in the dynamically formed QDs aggregates. A third system demonstrating transient, dissipative, luminescence properties of a reaction module consisting of nucleic acid-stabilized Ag nanoclusters (NCs) is introduced. Transient dynamic formation and depletion of the supramolecular luminescent Ag NCs system via strand displacement accompanied by a nicking process are demonstrated.

Abstract
In the past few decades, biosensors have been gradually developed for the rapid detection and monitoring of human diseases. Recently, functional nucleic-acid (FNA) biosensors have attracted the attention of scholars due to a series of advantages such as high stability and strong specificity, as well as the significant progress they have made in terms of biomedical applications. However, there are few reports that systematically and comprehensively summarize its working principles, classification and application. In this review, we primarily introduce functional modes of biosensors that combine functional nucleic acids with different signal output modes. In addition, the mechanisms of action of several media of the FNA biosensor are introduced. Finally, the practical application and existing problems of FNA sensors are discussed, and the future development directions and application prospects of functional nucleic acid sensors are prospected.

Abstract
Engineering of the cell plasma membrane using functional DNA is important for studying and controlling cellular behaviors. However, most efforts to apply artificial DNA interactions on cells are limited to external membrane surface due to the lack of suitable synthetic tools to engineer the intracellular side, which impedes many applications in cell biology. Inspired by the natural extracellular vesicle-cell fusion process, we have developed a fusogenic spherical nucleic acid construct to realize robust DNA functionalization on both external and internal cell surfaces via liposome fusion-based transport (LiFT) strategy, which enables applications including the construction of heterotypic cell assembly for programmed signaling pathway and detection of intracellular metabolites. This approach can engineer cell membranes in a highly efficient and spatially controlled manner, allowing one to build anisotropic membrane structures with two orthogonal DNA functionalities.

Rapid heavy metal sensing platform: A case of triple signal amplification strategy for the sensitive detection of serum copper. Anal Chim Acta 2021; 1181:338908.

Abstract
Heavy metals are considered as hazardous substances to human because of their toxicity, persistence and bioaccumulation, and the level in serum is an important factor to evaluate the caused health risk, which depends on efficient and sensitive analytical methods. Here, a triple signal-amplified electrochemical sensing platform based on metal-dependent DNAzymes was fabricated for sensitive determination of heavy metals in serum (copper as a model target). Under the optimized conditions, the proposed method showed good sensitivity (limit of detection, 0.33 fM for Cu2+) with excellent selectivity and stability, which is ascribed to: (i) tetrahedral DNA nanostructures (TDNs) that was used as a promising scaffold to adjust the selective transformation between heterogeneous and homogeneous reactions, preventing the nonspecific binding of electrodes surface and DNA probes; (ii) the magnetic beads (MBs) used which led to signal amplification and decreased background owing to its excellent properties of extracting equivalent targets from the complex samples; (iii) two signal amplification strategy of catalytic hairpin assembly (CHA) and hybridization chain reaction (HCR). In addition, the proposed sensing platform displayed satisfactory accuracy through the validation with inductively coupled plasma-mass spectrometry (ICP-MS) and a spike-recovery analysis (recoveries, 87.92-111.61%; RSD, 4.89-8.85%), indicating the great potential for rapid and sensitive detection of Cu2+ or other metal ions.

Abstract
Aim. The purpose of the review was to analyze the use of DNAzyme biosensors for the detection of pathogens. In the recent years, deoxyribozymes (DNAzymes) have a significant impact as biosensors in diverse fields, from detection of metal ions in the environment to theranostic applications and detection of microorganisms. Although routinely used sophisticated instrumental methods are available to detect pathogenic bacterial contamination, they involve time-consuming, complicated sample pre-treatment and expensive instruments. As an alternative, pathogen-specific DNAzymes have demonstrated a series of advantages: a non-destructive rapid analysis technique with in situ and real-time detection of bacteria with high sensitivity and selectivity. A wide range of pathogen-specific DNAzymes has been developed using colorimetric and fluorescence-based detections for pathogenic bacterial contamination in various samples. The current review summarizes the in vitro selection of pathogen-specific DNAzymes, various strategies utilized in the sensor designs, and their potential use in theranostic applications.

Development of a DNAzyme-based colorimetric biosensor assay for dual detection of Cd 2+ and Hg 2. Anal Bioanal Chem 2021; 413:7081-7091. [PMID: 34585255 DOI: 10.1007/s00216-021-03677-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 09/15/2021] [Accepted: 09/17/2021] [Indexed: 10/20/2022]
Abstract
A colorimetric biosensor assay has been developed for Cd2+ and Hg2+ detection based on Cd2+-dependent DNAzyme cleavage and Hg2+-binding-induced conformational switching of the G-quadruplex fragment. Two types of multifunctional magnetic beads (Cd-MBs and Hg-MBs) were synthesized by immobilizing two functionalized DNA sequences on magnetic beads via avidin-biotin chemistry. For Cd2+ detection, Cd-MBs are used as recognition probes, which are modified with a single phosphorothioate ribonucleobase (rA) substrate (PS substrate) and a Cd2+-specific DNAzyme (Cdzyme). In the presence of Cd2+, the PS substrate is cleaved by Cdzyme, and single-stranded DNA is released as the signal transduction sequence. After molecular assembly with the other two oligonucleotides, duplex DNA is produced, and it can be recognized and cleaved by FokI endonuclease. Thus, a signal output component consisting of a G-quadruplex fragment is released, which catalyzes the oxidation of ABTS with the addition of hemin and H2O2, inducing a remarkably amplified colorimetric signal. To rule out false-positive results and reduce interference signals, Hg-MBs modified with poly-T fragments were used as Hg2+ accumulation probes during the course of Cd2+ detection. On the other hand, Hg-MBs can perform their second function in Hg2+ detection by changing the catalytic activity of the G-quadruplex/hemin DNAzyme. In the presence of Hg2+, the G-quadruplex structure in Hg-MBs is disrupted upon Hg2+ binding. In the absence of Hg2+, an intensified color change can be observed by the naked eye for the formation of intact G-quadruplex/hemin DNAzymes. The biosensor assay exhibits excellent selectivity and high sensitivity. The detection limits for Cd2+ and Hg2+ are 1.9 nM and 19.5 nM, respectively. Moreover, the constructed sensors were used to detect environmental water samples, and the results indicate that the detection system is reliable and could be further used in environmental monitoring. The design strategy reported in this study could broadly extend the application of metal ion-specific DNAzyme-based biosensors.

Abstract
Adenosine 5'-triphosphate (ATP) is a central extracellular signaling agent involved in various physiological and pathological processes. However, precise measurements of the temporal and spatial components of ATP dynamics are lacking due primarily to the limitations of available methods for ATP detection. Here, we report on the first effort to design a self-phosphorylating DNAzyme (SPDz) sensor for fluorescence imaging of ATP. In response to ATP, SPDz sensors exhibit subsecond response kinetics, extremely high specificity, and micromolar affinities. In particular, we demonstrate cell-surface-anchored SPDz sensors for fluorescence imaging of both stress-induced endogenous ATP release in astrocytes and mechanical stimulation-evoked ATP release at the single-cell level. We also validated their utility for visualizing the rapid dynamic properties of ATP signaling upon electrical stimulation in astrocytes. Thus, SPDz sensors are robust tools for monitoring ATP signaling underlying diverse cellular processes.

Abstract
Pyrethroid pesticides residues will not only pollute the environment, but also cause high toxicity to the human body. It is significant to establish an efficient and accurate method for pyrethroid detection in food. Considering that the common biomolecules like antibody is complicated and easy to inactivate, it is urgent to find a new type of biomolecule to specifically recognize pyrethroid pesticides. This study proposed the Capture-SELEX strategy to firstly select λ-cyhalothrin aptamer by immobilizing random ssDNA library. High-throughput sequencing was performed on the enriched ssDNA library through multiple Capture-SELEX rounds. Comprehensively inspecting structural similarity and homology, six sequences were chosen from five families for further analysis. The results showed that the aptamer (named LCT-1) could specifically recognize λ-cyhalothrin with the strongest affinity (Kd = 50.64 ± 4.33 nmol L-1). Molecular docking results revealed that the binding sites between λ-cyhalothrin and LCT-1 aptamer are mainly related to the bases A-5, C-6, C-28, A-29, C-30, G-31 and G-32. The LCT-1 aptamer was truncated to a shorter sequence (named as LCT-1-39) by removing other irrelevant bases, and its Kd value was determined as (10.27 ± 1.33) nmol·L-1 by Microscale Thermophoresis (MST). Both LCT-1 and LCT-1-39 aptamers were employed as recognition molecules to establish the colorimetric aptasensors for λ-cyhalothrin detection, which displayed good repeatability and reproducibility. The detection limit of the aptasensors were individually calculated as 0.0197 μg ml-1 and 0.0186 μg ml-1, and their recovery rate of λ-cyhalothrin in pear and cucumber samples was in the range of 82.93-95.50%. This article provides a promising application for the detection of λ-cyhalothrin.

Abstract
Molecular probe that enables in vivo imaging is the cornerstone of accurate disease diagnosis, prognostic estimation, and therapies. Although several nucleic acid-based probes have been reported for tumor detection, it is still a challenge to develop programmable methodology for accurately identifying tumors in vivo. Herein, a reconfigurable DNA hybridization-based reaction was constructed to assemble DNAzyme computing that contains an intracellular miRNA-unlocked entropy-driven catalysis module and an endogenous metal ion-responsive DNAzyme module for specific in vivo imaging. By reasonable design, the programmable DNAzyme computing can not only successfully distinguish tumor cells from normal cells but also enable tumor imaging in living mice. Due to its excellent operation with high specificity and sensitivity, this design may be broadly applied in the biological study and personalized medicine.

Abstract
Functionalized hyperpolarized xenon "cage" molecules have often been used for ultrasensitive detection of biomolecules and microenvironment properties. However, the rapid and accurate measurement of molecule concentration is still a challenge. Here, we report a molecule concentration measurement method using long-interval chemical exchange inversion transfer (CEIT) NMR spectroscopy. The molecule concentration can be quantitatively measured with only 2 scans, which shortens the acquisition time by about 10 times compared to conventional Hyper-CEST (chemical exchange saturation transfer) z-spectrum method. Moreover, we found that the accuracy of concentration determination would be the best when the CEIT effect is 1-1/e or close to it, and a relative deviation of CrA-(COOH)6 less than ±1% has been achieved by only a one-step optimization of the number of cycles. The proposed method enables efficient and accurate determination of molecule concentration, which provides a potential way for rapid quantitative molecular imaging applications.

Abstract
![]()
An undecamer oligonucleotide probe
based on a pair of deoxythymidines
flanked by several modified nucleotides is a specific and highly efficient
biosensor for micrococcal nuclease (MNase), an endonuclease produced
by Staphylococcus aureus. Herein, the
interaction mode and cleavage process on such oligonucleotide probes
are identified and described for the first time. Also, we designed
truncated pentamer probes as the minimum-length substrates required
for specific and efficient biosensing. By means of computational (virtual
docking) and experimental (ultra-performance liquid chromatography–mass
spectrometry and matrix-assisted laser desorption ionization time-of-flight)
techniques, we perform a sequence/structure–activity relationship
analysis, propose a catalytically active substrate–enzyme complex,
and elucidate a novel two-step phosphodiester bond hydrolysis mechanism,
identifying the cleavage sites and detecting and quantifying the resulting
probe fragments. Our results unravel a picture of both the enzyme–biosensor
complex and a two-step cleavage/biosensing mechanism, key to the rational
oligonucleotide design process.

Abstract
Developing spherical nucleic acids with new structures holds great promise for nanomedicine and bioanalytical fields. Covalent organic frameworks (COFs) are emerging promising materials with unique properties for a wide range of applications. However, devising COF-based spherical nucleic acid is challenging because methods for the preparation of functionalized COFs are still limited. We report here a bonding defect-amplified modification (BDAM) strategy for the facile preparation of functionalized COFs. Poly(acrylic acid) was employed as the defect amplifier to modify the surface of COF nanoparticles by the formation of amide bonds with amino residues, which successfully converted and amplified the residues into abundant reactive carboxyl groups. Then, amino terminal-decorated hairpin DNA was densely grafted onto the surface of COF nanoparticles (NPs) to give rise to a spherical nucleic acid probe (SNAP). A series of experiments and characterizations proved the successful preparation of the COF-based SNAP, and its application in specifically lighting up RNA biomarkers in living cells for cancer diagnostic imaging was demonstrated. Therefore, the COF-based SNAP is a promising candidate for biomedical applications and the proposed BDAM represents a useful strategy for the preparation of functionalized COFs for diverse fields.

Abstract
Synthetic molecular robots can execute sophisticated molecular tasks at nanometer resolution. However, a molecular robot capable of controlling cellular behavior remains unexplored. Herein, we report a self-propelled DNA robot operating on the cell membrane to control the migration of a cell. Driven by DNAzyme catalytic activity, the DNA robot could autonomously and stepwise move on the membrane-floating cell-surface receptors in a stochastic manner and simultaneously trigger the receptor-dimerization to activate downstream signaling for cell motility. The cell membrane-associated continuous motion and operation of a DNA robot allowed for the ultrasensitive regulation of MET/AKT signaling and cytoskeleton remodeling to enhance cell migration. Finally, we designed distinct conditional DNA robots to orthogonally manipulate the cell migration in a coculture of mixed cell populations. We have developed a novel strategy to engineer a cell-driving molecular robot, representing a promising avenue for precise cell manipulation with nanoscale resolution.

Abstract
Excessive mercury ions (Hg2+) cause great pollution to soil/water and pose a major threat to human health. The high sensitivity and high selectivity in the Hg2+ detection demonstrated herein are significant for the research areas of analytical chemistry, chemical biology, physical chemistry, drug discovery, and clinical diagnosis. In this study, a series of simple, low-cost, and highly sensitive biochips based on a graphene oxide (GO)/DNA hybrid was developed. Hg2+ is detected with high sensitivity and selectivity by GO/DNA hybrid biochips immobilized on glass slides. The performance of the biosensors can be improved by introducing more phosphorothioate sites and complementary bases. The best limit of detection of the biochips is 0.38 nM with selectivity of over 10:1. This sensor was also used for Hg2+ detection in Dendrobium. The results show this biochip is promising for Hg2+ detection.

Abstract
Protease-triggered control of functional DNA has remained unachieved, leaving a significant gap in activatable DNA biotechnology. Here we disclose the design of a protease-activatable aptamer technology that can perform molecular sensing and imaging function in a tumor-specific manner. The system is constructed by locking structure-switching activity of aptamer using a rationally designed PNA-peptide-PNA triblock copolymer. Highly selective cleavage of the peptide substrate is achieved by protease-mediated enzymatic reaction that result in reduced binding affinity of PNA to the aptamer module, with the subsequently recovering its biosensing function. We demonstrated that the DNA/peptide/PNA hybrid system not only allows for tumor cell-selective ATP imaging in vitro , but it also produce a fluorescent signal in vivo with improved tumor specificity. This work illustrates the potential of bridging the gap between functional DNA field and peptide area for precise biomedical applications.

Abstract
Accurate diagnosis and targeted therapy are essential to precision theranostics. However, nonspecific response of theranostic agents in healthy tissues impedes their practical applications. Here, we design an activatable DNA nanosphere for specifically in situ sensing of cancer biomarker flap endonuclease 1 (FEN1) and spatiotemporally modulating drug release. The gold nanostar-conjugated FEN1 substrate acts as spherical nucleic acid and induces a fluorescence signal upon a FEN1 stimulus for diagnosis. Guided by the nanoflare, external NIR light then triggers a controlled release of carried drugs at desired sites. This DNA nanosphere not only exhibits good stability, sensitivity, and specificity toward FEN1 assay but also serves as a precision theranostic agent for targeted and controlled drug delivery. Our study provides a reliable method for FEN1 imaging in vitro and in vivo and suggests a powerful strategy for precision medicine.

Abstract
Ligand-oligonucleotide transduction provides the critical pathway to integrate non-nucleic acid molecules into nucleic acid circuits and nanomachines for a variety of strand-displacement related applications. Herein, a general platform is constructed to convert the signals of ligands into desired oligonucleotides through a precise kinetic control. In this design, the ligand-aptamer binding sequence with an engineered duplex stem is introduced between the toehold and displacement domains of the invading strand to regulate the strand-displacement reaction. Employing this platform, we achieve efficient transduction of both small molecules and proteins orthogonally, and more importantly, establish logical and cascading operations between different ligands for versatile transduction. Besides, this platform is capable of being directly coupled with the signal amplification systems to further enhance the transduction performance. This kinetically controlled platform presents unique features with designing simplicity and flexibility, expandable complexity and system compatibility, which may pave a broad road towards nucleic acid-based developments of sophisticated transduction networks.

Abstract
A gold nanoparticle-based label-free colorimetric assay was developed to detect the shrimp allergenic protein tropomyosin (TM), an important biomarker responsible for severe clinical reactivity to shellfish. In a gold nanoparticles (AuNPs)-tropomyosin-binding aptamer (TMBA) complex, the aptamer adsorbs onto the surface of AuNPs and dissociates in the presence of TM. In addition, AuNPs tend to aggregate in the presence of ionic salt, revealing a color change (i.e., wine-red to purple/blue) with a shift in the maximum absorption peak from 520 nm. In the presence of specific binding TM, the aptamer folds into a tertiary structure where it more efficiently stabilizes AuNPs toward the salt-induced aggregation with a hypsochromic shift in the absorption spectra compared to the stabilized AuNPs by aptamer alone. Based on the aggregation and sensitive spectral transformation principle, the AuNPs-based colorimetric aptasensor was successfully applied to detect TM with a range of 10-200 nmol/L and a low detection limit of 40 nmol/L in water samples. The reliability, selectivity, and sensitivity of the aptasensor was then tested with food samples spiked with TM. The observed detection limit was as low as 70 nmol/L in shrimp, 90 nmol/L in tofu, and 80 nmol/L in eggs, respectively. We anticipate the proposed AuNPs-based colorimetric aptasensor assay possesses a high potential for the easy and efficient visual colorimetric detection of TM.

Abstract
Dynamic nanoassembly-based drug delivery system (DNDDS) has evolved from being a mere curiosity to emerging as a promising strategy for high-performance diagnosis and/or therapy of various diseases. However, dynamic nano-bio interaction between DNDDS and biological systems remains poorly understood, which can be critical for precise spatiotemporal and functional control of DNDDS in vivo. To deepen the understanding for fine control over DNDDS, we aim to explore natural systems as the root of inspiration for researchers from various fields. This review highlights ingenious designs, nano-bio interactions, and controllable functionalities of state-of-the-art DNDDS under endogenous or exogenous stimuli, by learning from nature at the molecular, subcellular, and cellular levels. Furthermore, the assembly strategies and response mechanisms of tailor-made DNDDS based on the characteristics of various diseased microenvironments are intensively discussed. Finally, the current challenges and future perspectives of DNDDS are briefly commented.

Abstract
Direct measurement of DNA repair is critical for the annotation of their clinical relevance and the discovery of drugs for cancer therapy. Here we reported a "repaired and activated" DNAzyme (RADzyme) by incorporating a single methyl lesion (O6 MeG, 3MeC, or 1MeA) at designated positions through systematic screening. We found that the catalytic activity of the RADzyme was remarkably suppressed and could be restored via enzyme-mediated DNA repair. Benefit from these findings, a fluorogenic RADzyme sensor was developed for the monitoring of MGMT-mediated repair of O6 MeG lesion. Importantly, the sensor allowed the evaluation of MGMT repair activity in different cells and under drugs treatment. Furthermore, another RADzyme sensor was engineered for the monitoring of ALKBH2-mediated repair of 3MeC lesion. This strategy provides a simple and versatile tool for the study of the basic biology of DNA repair, clinical diagnosis and therapeutic assessment.

Abstract
The synthesis of light-responsive nanocarriers (LRNs) with a variety of surface functional groups and/or ligands has been intensively explored for space-temporal controlled cargo release. LRNs have been designed on demand for photodynamic-, photothermal-, chemo-, and radiotherapy, protected delivery of bioactive molecules, such as smart drug delivery systems and for theranostic duties. LRNs trigger the release of cargo by a light stimulus. The idea of modifying LRNs with different moieties and ligands search for site-specific cargo delivery imparting stealth effects and/or eliciting specific cellular interactions to improve the nanosystems’ safety and efficacy. This work reviews photoresponsive polymeric nanocarriers and photo-stimulation mechanisms, surface chemistry to link ligands and characterization of the resultant nanosystems. It summarizes the interesting biomedical applications of functionalized photo-controlled nanocarriers, highlighting the current challenges and opportunities of such high-performance photo-triggered delivery systems.

Abstract
Aptamers are short oligonucleotides isolated in vitro from randomized libraries that can bind to specific molecules with high affinity, and offer a number of advantages relative to antibodies as biorecognition elements in biosensors. However, it remains difficult and labor-intensive to develop aptamer-based sensors for small-molecule detection. Here, we review the challenges and advances in the isolation and characterization of small-molecule-binding DNA aptamers and their use in sensors. First, we discuss in vitro methodologies for the isolation of aptamers, and provide guidance on selecting the appropriate strategy for generating aptamers with optimal binding properties for a given application. We next examine techniques for characterizing aptamer-target binding and structure. Afterwards, we discuss various small-molecule sensing platforms based on original or engineered aptamers, and their detection applications. Finally, we conclude with a general workflow to develop aptamer-based small-molecule sensors for real-world applications.

Gold-Oligonucleotide Nanoconstructs Engineered to Detect Conserved Enteroviral Nucleic Acid Sequences. BIOSENSORS-BASEL 2021; 11:bios11070238.

Abstract
Enteroviruses are ubiquitous mammalian pathogens that can produce mild to life-threatening disease. We developed a multimodal, rapid, accurate and economical point-of-care biosensor that can detect nucleic acid sequences conserved amongst 96% of all known enteroviruses. The biosensor harnesses the physicochemical properties of gold nanoparticles and oligonucleotides to provide colourimetric, spectroscopic and lateral flow-based identification of an exclusive enteroviral nucleic acid sequence (23 bases), which was identified through in silico screening. Oligonucleotides were designed to demonstrate specific complementarity towards the target enteroviral nucleic acid to produce aggregated gold–oligonucleotide nanoconstructs. The conserved target enteroviral nucleic acid sequence (≥1 × 10−7 M, ≥1.4 × 10−14 g/mL) initiates gold–oligonucleotide nanoconstruct disaggregation and a signal transduction mechanism, producing a colourimetric and spectroscopic blueshift (544 nm (purple) > 524 nm (red)). Furthermore, lateral-flow assays that utilise gold–oligonucleotide nanoconstructs were unaffected by contaminating human genomic DNA, demonstrated rapid detection of conserved target enteroviral nucleic acid sequence (<60 s), and could be interpreted with a bespoke software and hardware electronic interface. We anticipate that our methodology will translate in silico screening of nucleic acid databases to a tangible enteroviral desktop detector, which could be readily translated to related organisms. This will pave the way forward in the clinical evaluation of disease and complement existing strategies to overcome antimicrobial resistance.

Abstract
The biological olfactory system is the sensory system responsible for the detection of the chemical composition of the environment. Several attempts to mimic biological olfactory systems have led to various artificial olfactory systems using different technical approaches. Here we provide a parallel description of biological olfactory systems and their technical counterparts. We start with a presentation of the input to the systems, the stimuli, and treat the interface between the external world and the environment where receptor neurons or artificial chemosensors reside. We then delineate the functions of receptor neurons and chemosensors as well as their overall I-O relationships. Up to this point, our account of the systems goes along similar lines. The next processing steps differ considerably: while in biology the processing step following the receptor neurons is the "integration" and "processing" of receptor neuron outputs in the olfactory bulb, this step has various realizations in electronic noses. For a long period of time, the signal processing stages beyond the olfactory bulb, i.e., the higher olfactory centers were little studied. Only recently there has been a marked growth of studies tackling the information processing in these centers. In electronic noses, a third stage of processing has virtually never been considered. In this review, we provide an up-to-date overview of the current knowledge of both fields and, for the first time, attempt to tie them together. We hope it will be a breeding ground for better information, communication, and data exchange between very related but so far little connected fields.

Abstract
Nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are natural biopolymers composed of nucleotides that store, transmit, and express genetic information. Overexpressed or underexpressed as well as mutated nucleic acids have been implicated in many diseases. Therefore, nucleic acid tests (NATs) are extremely important. Inspired by intracellular DNA replication and RNA transcription, in vitro NATs have been extensively developed to improve the detection specificity, sensitivity, and simplicity. The principles of NATs can be in general classified into three categories: nucleic acid hybridization, thermal-cycle or isothermal amplification, and signal amplification. Driven by pressing needs in clinical diagnosis and prevention of infectious diseases, NATs have evolved to be a rapidly advancing field. During the past ten years, an explosive increase of research interest in both basic research and clinical translation has been witnessed. In this review, we aim to provide comprehensive coverage of the progress to analyze nucleic acids, use nucleic acids as recognition probes, construct detection devices based on nucleic acids, and utilize nucleic acids in clinical diagnosis and other important fields. We also discuss the new frontiers in the field and the challenges to be addressed.

Abstract
Food safety monitoring assays based on synthetic recognition structures such as aptamers are receiving considerable attention due to their remarkable advantages in terms of their ability to bind to a wide range of target analytes, strong binding affinity, facile manufacturing, and cost-effectiveness. Although aptasensors for food monitoring are still in the development stage, the use of an electrochemical detection route, combined with the wide range of materials available as transducers and the proper immobilization strategy of the aptamer at the transducer surface, can lead to powerful analytical tools. In such a context, employing aryldiazonium salts for the surface derivatization of transducer electrodes serves as a simple, versatile and robust strategy to fine-tune the interface properties and to facilitate the convenient anchoring and stability of the aptamer. By summarizing the most important results disclosed in the last years, this article provides a comprehensive review that emphasizes the contribution of aryldiazonium chemistry in developing electrochemical aptasensors for food safety monitoring.

Abstract
DNAzymes have been widely used in many sensing and imaging applications but have rarely been used for genetic engineering since their discovery in 1994, because their substrate scope is mostly limited to single-stranded DNA or RNA, whereas genetic information is stored mostly in double-stranded DNA (dsDNA). To overcome this major limitation, we herein report peptide nucleic acid (PNA)-assisted double-stranded DNA nicking by DNAzymes (PANDA) as the first example to expand DNAzyme activity toward dsDNA. We show that PANDA is programmable in efficiently nicking or causing double strand breaks on target dsDNA, which mimics protein nucleases and can act as restriction enzymes in molecular cloning. In addition to being much smaller than protein enzymes, PANDA has a higher sequence fidelity compared with CRISPR/Cas under the condition we tested, demonstrating its potential as a novel alternative tool for genetic engineering and other biochemical applications.

Abstract
The COVID-19 pandemic revealed during the first global wave of this infectious disease that mass diagnostic testing was necessary to more rapidly detect infection in patients and control the pandemic. Therefore, extra research efforts to develop reliable and more accessible techniques for disease diagnosis are of supreme importance. Here, a target-responsive assembly of gold nanoparticle-core hairpin-spherical nucleic acids (AuNP-core H-SNAs) was implemented to modify the conventional polymerase chain reaction (PCR) assay for the "naked-eye" colorimetric detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA. Two hairpin DNA ligands are designed based on the two highly conserved regions within N and E genes of SARS-CoV-2 RNA by positioning two short palindromic arms (stem) on either side of a recognition sequence (loop). In the presence of a sequence-specific probe (activator), hairpin DNAs anchored to the surface of AuNPs unfold and expose the palindromic ends to the DNA-directed assembly of AuNPs. The sequence of the activator probes was chosen to be identical to the TaqMan probe in a real-time reverse transcription PCR (RT-PCR) assay for specifically targeting the N and E genes of SARS-CoV-2 RNA. They may either be degraded by the 5'-exonuclease activity of DNA polymerase during PCR cycles or stay intact depending on the presence or absence of the target template in the sample, respectively. Post-addition of H-SNA solutions to the final PCR products of some preconfirmed clinical samples for COVID-19 generated naked-eye-observable red and blue colors for positive and negative cases, respectively, with similar sensitivity to that of the real-time RT-PCR method.

Abstract
Of the multiple areas of applications of DNA nanotechnology, stimuli-responsive nanodevices have emerged as an elite branch of research owing to the advantages of molecular programmability of DNA structures and stimuli-responsiveness of motifs and DNA itself. These classes of devices present multiples areas to explore for basic and applied science using dynamic DNA nanotechnology. Herein, we take the stake in the recent progress of this fast-growing sub-area of DNA nanotechnology. We discuss different stimuli, motifs, scaffolds, and mechanisms of stimuli-responsive behaviours of DNA nanodevices with appropriate examples. Similarly, we present a multitude of biological applications that have been explored using DNA nanodevices, such as biosensing, in vivo pH-mapping, drug delivery, and therapy. We conclude by discussing the challenges and opportunities as well as future prospects of this emerging research area within DNA nanotechnology.

Abstract
The RNA-cleaving 17E DNAzyme exhibits different levels of cleavage activity in the presence of various divalent metal ions, with Pb2+ giving the fastest cleavage. In this study, the metal-phosphate interaction is probed to understand the trend of activity with different metal ions. For the first-row transition metals, the lowest activity shown by Ni2+ correlates with the inhibition by the inorganic phosphate and its water ligand exchange rate, suggesting inner-sphere metal coordination. Cleavage activity with the two stereoisomers of the phosphorothioate-modified substrates, Rp and Sp, indicated that Mg2+, Mn2+, Fe2+, and Co2+ had the highest Sp:Rp activity ratio of >900. Comparatively, the activity was much less affected using the thiophilic metals, including Pb2+, suggesting inner-sphere coordination. The pH-rate profiles showed that Pb2+ was different than the rest of the metal ions in having a smaller slope and a similar fitted apparent pKa and the pKa of metal-bound water. Combining previous reports and our current results, we propose that Pb2+ most likely plays the role of a general acid while the other metal ions are Lewis acid catalysts interacting with the scissile phosphate.

Abstract
During its development in recent decades, DNAzyme has become a promising candidate for application in biosensor field. However, it still suffers from the problem of thermodynamic and biological instability such as nuclease digestion, which limits its applications in complex samples. Here we have presented a simple and common strategy to resolve this problem by engineering the linear DNAzyme into a circular shape DNAzyme based on the integration of substrate and enzyme parts into one single-stranded sequence. This circular DNAzyme system is indeed endowed with excellent stability due to the stable intramolecular double-stranded formation and extraordinary resistance to nuclease digestion due to the closed structure. We demonstrated that this circular DNAzyme system gained excellent stability and could active under conditions across a broader range of temperature, salt concentrations, and pH. Depending on this circular DNAzyme, combing with Terminal deoxynucleotidyl transferase (TdT)-generated G-quadruplexes, a label free colorimetric sensing platform for Pb2+ quantitation was developed, and a detection limit of 0.085 nM was achieved. Then the enzyme digestion cycle amplification was introduced to further improve the sensitivity of the sensing system, an ultralow detection limit of 0.0015 nM for this fluorescence method was achieved. Based on the two sensing platforms, ultrasensitive analysis of Pb2+ in environmental water and food samples was successfully realized. It is anticipated that this stable circular DNAzyme design will be helpful for trace detection in complex samples.

Abstract
Using the principle of binding-induced DNA strand displacement (BINSD), a DNAzyme-powered nanomachine biosensor for multiple biomarkers via magnetic beads-based signal conversion was designed. This sensor can convert multiple biomarker recognition into release of predesigned output nucleic acids tagged with streptavidin proteins (SA-DNA) for activation of DNA nanomachines. In general, we adopted complementary base pairing rules and affinity ligand specific recognition, and three types of signal conversion systems were constructed that realized universal, sensitive, accurate, and specific detection of multiple biomarkers. Taking the advantage of the strong anti-interference capability of magnetic separation, this strategy could be used for detection of various biomarkers in clinical practice.

Abstract
The construction of a novel class of indazolo[2,1-a]cinnolin-7-ium and diazabenzofluoranthenium salts was developed by using Rh(iii)-catalyzed C-H activation/annulation reactions with 2-phenyl-2H-indazole, and internal alkynes, which resulted in structurally important polycyclic heteroaromatic compounds (PHAs). This reaction uses mild reaction conditions and has a high efficiency, low catalyst loading, and wide substrate scope. The overall catalytic process involves C-H activation followed by C-C/C-N bond formation. Furthermore, the synthesised cinnolinium/fluoranthenium salts exhibit potential fluorescence properties and 5i was targeted in particular for specific mitochondrial staining in order to investigate cancer cell lines.

Abstract
RNA-cleaving DNAzymes are widely applied as sensors for detecting metal ions in environmental samples owing to their high sensitivity and selectivity, but their use for sensing biological metal ions in live cells is challenging because constitutive sensors fail to report the spatiotemporal heterogeneity of biological processes. Photocaged DNAzymes can be activated by light for sensing purposes that need spatial and temporal resolution. Studying complex biological processes requires logic photocontrol, but unfortunately all the literature-reported photocaged DNAzymes working in live cells cannot be selectively controlled by light irradiation at different wavelengths. In this work, we developed photocaged DNAzymes responsive to UV and visible light using a general synthetic method based on phosphorothioate chemistry. Taking the Zn2+-dependent DNAzyme sensor as a model, we achieved wavelength-selective activation of photocaged DNAzymes in live human cells by UV and visible light, laying the groundwork for the logic activation of DNAzyme-based sensors in biological systems.

Abstract
Lead poisoning endangers soil, plants and human health due to its toxic effect. It is urgent to develop ideal tool for the in vivo detection of Pb2+.In this study, tetrahedron-based Pb2+-sensitive DNAzyme sensor (TPS) is constructed by taking advantages of a classic Pb2+-dependent GR-5 DNAzyme and DNA tetrahedral structure, where the cleavage substrate and DNAzyme are modified with fluorophore FAM and quencher BHQ-1, respectively. DNA tetrahedron is arranged at the terminus of substrate/DNAzyme duplex to offer the protective shield against the nuclease attack. In the absence of Pb2+, FAM and BHQ-1 are kept close and FAM fluorescence is efficiently quenched. However, in the presence of Pb2+ cofactor, the DNAzyme exhibits the catalytic activity and cleaves the substrate strands, spatially separating the FAM away from BHQ-1 and releasing fluorescence. Utilizing the sensing probe, the Pb2+ can be quantitatively detected down to 1 nM without the interference from nontarget metal ions. Even if incubating in the human serum solution for 12 h, no substantial nuclease degradation is detected. In different complex biological milieu, the TPS can preserve the 85% of fluorescence signal, indicating that the developed TPS is a promising tool for the future application in the in vivo detection of Pb2+.

Abstract
Functional nucleic acids (FNAs), including naturally occurring ribozymes and riboswitches as well as artificially created DNAzymes and aptamers, have been popular molecular toolboxes for diverse applications. Given the high chemical stability of nucleic acids and their ability to fold into diverse sequence-dependent structures, FNAs are suggested to be highly functional under unusual reaction conditions. This review will examine the progress of research on FNAs under conditions of low pH, high temperature, freezing conditions, and the inclusion of organic solvents and denaturants that are known to disrupt nucleic acid structures. The FNA species to be discussed include ribozymes, riboswitches, G-quadruplex-based peroxidase mimicking DNAzymes, RNA-cleaving DNAzymes, and aptamers. Research within this space has not only revealed the hidden talents of FNAs but has also laid important groundwork for pursuing these intriguing functional macromolecules for unique applications.

Abstract
Despite the great efforts of using DNAzyme for gene therapy, its clinical success is limited by the lack of simple delivery systems and limited anticancer efficacy. Here, we develop a simple approach for the synthesis of hybrid nanostructures that exclusively consist of DNAzyme and Cu2+ with ultra-high loading capacity. The Cu-DNAzyme nanohybrids allow to effectively co-deliver DNAzyme and Cu2+ into cancer cells for combinational catalytic therapy. The released Cu2+ can be reduced to Cu+ by glutathione and then catalyze endogenous H2 O2 to form cytotoxic hydroxyl radicals for chemodynamic therapy (CDT), while the 10-23 DNAzyme enables the catalytic cleavage of VEGFR2 mRNA and activates gene silencing for gene therapy. We demonstrate that the system can efficiently accumulate in the tumor and exhibit amplified cascade antitumor effects with negligible systemic toxicity. Our work paves an extremely simple way to integrate DNAzyme with CDT for the dual-catalytic tumor treatment.

Abstract
The sensitive and quantitative analysis of mucin 1 (MUC1) is very important for the prevention and early diagnosis of cancers. In the present work, based on the mechanism of the four-way DNA branch migration cascades, we constructed a simple and effective signal amplification strategy for aptamer-based sensitive detection of MUC1. The specific binding of MUC1 to the aptamer sequence in the hairpin probe unfolds and switches its structure, triggering the formation of the DNA Holliday junction structure for cascaded branch migrations with the assistance of two fuel DNA duplexes. Importantly, a target analogue DNA complex can be generated in such processes for recycling the branch migration reactions for the production of substantial amounts of G-quadruplexes, which can bind the thioflavin T dye to show significantly intensified fluorescence for detecting MUC1 with a low detection limit of 2.8 nM without the involvement of any labels or enzymes. In addition, this detection strategy could be successfully applied to monitor the target MUC1 in diluted human serums with a high selectivity and acceptable accuracy to demonstrate its potential application for real samples with the advantages of simplicity and signal amplification capability.

Abstract
Adenine is a key nucleobase, adenosine is an endogenous regulator of the immune system, while adenosine triphosphate (ATP) is the energy source of many biological reactions. Selective detection of these molecules is useful for understanding biological processes, biochemical reactions and signaling. Since 1993, various aptamers have been reported to bind to adenine and its derivatives. In addition, the adenine riboswitch was later discovered. This review summarizes the efforts for the selection of RNA and DNA aptamers for adenine derivatives, and we pay particular attention to the specificity of binding. In addition, other molecular recognition strategies based on rational sequence design are also introduced. Most of the work in the field was performed on the classic DNA aptamer for adenosine and ATP reported by the Szostak group. Based on this aptamer, some representative applications such as the design of fluorescent, colorimetric and electrochemical biosensors, intracellular imaging, and ATP-responsive materials are also described. In addition, we critically review the limit of the reported aptamers and also important problems in the field, which can give future research opportunities.
