Abstract
PIWI-interacting RNAs (piRNAs) are a type of endogenous noncoding RNAs with a length of 24-31 nucleotides, and they can specifically bind with PIWI proteins to form the piRNA/PIWI complexes for regulating multiple physiological and pathological processes. Herein, we develop a bidirectional polymerization-transcription amplification-encoded dual-color fluorescent biosensor for label-free and primer-free measurements of multiple piRNAs. The designed hairpin probe contains a palindromic tail, and it can serve as the target recognition unit, polymerization primer, and transcription template. In the presence of target piRNAs, the hairpin probes are opened to expose a palindromic sequence that can trigger bidirectional polymerization and transcription reaction with the assistance of KF polymerase and T7 RNA polymerase for the production of numerous RNA aptamers. The aptamers subsequently bind with the corresponding fluorophores (DFHBI-1T/MG) to form the RNA aptamer-fluorophore complexes for the generation of enhanced fluorescence signals. This biosensor can sensitively detect piR-36026 with a limit of detection (LOD) of 82.08 aM and piR-36743 with a LOD of 44.44 aM. Moreover, it can quantify cellular piRNAs with single-cell sensitivity and distinguish cancer cells from normal cells. Furthermore, it has the capability of distinguishing the expression of piRNAs in the tissues of breast cancer patients and healthy individuals. By simply altering the target recognition site of the hairpin probe, this biosensor can be extended to detect various piRNAs, offering a powerful platform for piRNA-related clinical diagnostics and therapeutics.

Abstract
DNAzymes, a class of single-stranded catalytic DNA with good stability, high catalytic activity, and easy synthesis, functionalization and modification properties, have garnered significant interest in the realm of biosensing and bioimaging. Their integration with fluorescent dyes or chemiluminescent moieties has led to remarkable bioimaging outcomes, while DNAzyme-based biosensors have demonstrated robust sensitivity and selectivity in detecting metal ions, nucleic acids, proteins, enzyme activities, exosomes, bacteria and microorganisms. In addition, by delivering DNAzymes into tumor cells, the mRNA therein can be cleaved to regulate the expression of corresponding proteins, which has further propelled the application of DNAzymes in cancer gene therapy and synergistic therapy. This paper reviews the strategies for screening attractive DNAzymes such as SELEX and high-throughput sequencing, and briefly describes the amplification strategies of DNAzymes, which mainly include catalytic hairpin assembly (CHA), DNA walker, hybridization chain reaction (HCR), DNA origami, CRISPR-Cas12a, rolling circle amplification (RCA), and aptamers. In addition, applications of DNAzymes in bioimaging, biosensing, and cancer therapy are also highlighted. Subsequently, the possible challenges of these DNAzymes in practical applications are further pointed out, and future research directions are suggested.

Abstract
Cascade isothermal nucleic acid amplification, which integrates several different amplification protocols to enhance the assay performance, is widely utilized in biosensing, particularly for detecting microRNAs (miRNAs), crucial biomarkers associated with tumor initiation and progression. However, striking a balance between a high amplification efficiency and simplicity in design remains a challenge. Therefore, methods achieving high amplification efficiency without significantly increasing complexity are highly favored. In this study, we propose a novel approach for miRNA detection, employing cross-priming-linked hierarchical isothermal amplification (CP-HIA) to progressively activate the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system. The CP-HIA method strategically combines nicking-rolling circle amplification (n-RCA) and palindrome-aided circular strand displacement amplification (p-CSDA) for miRNA detection. Remarkably, this method utilizes only two main probes. Its key innovation lies in the interactive cross-priming strategy, wherein the amplification product from n-RCA is recycled to further drive p-CSDA, and vice versa. This interactive process establishes a hierarchical amplification, significantly enriching the activation probes for progressive CRISPR/Cas12a activation and subsequent target signal amplification. Consequently, the method exhibits greatly enhanced analytical performance, including high sensitivity and specificity in detecting low concentrations of miRNA. As low as 1.06 fM miRNA can thus be quantitatively detected, and the linear response of the miRNA is from 10 fM to 10 nM. These features demonstrate its potential for early disease diagnosis and monitoring. We anticipate that the CP-HIA method will serve as a promising platform for developing advanced molecular diagnostic tools for biomedical research.

Abstract
Herein, we demonstrate a simple, homogenous and label-free electrochemical biosensing system for sensitive nucleic acid detection based on target-responsive porous materials and nuclease-triggered target recycling amplification. The Fe(CN)63- reporter was firstly sealed into the pores of Fe3O4 nanoparticles by probe DNA. Target DNA recognition triggered the controllable release of Fe(CN)63- for the redox reaction with the electron mediator of methylene blue enriched in the dodecanethiol assembled electrode and thereby generating electrochemical signal. The exonuclease III (Exo III)-assisted target recycling and the catalytic redox recycling between Fe(CN)63- and methylene blue contributed for the enhanced signal response toward target recognition. The low detection limit toward target was obtained as 478 fM and 1.6 pM, respectively, by square wave voltammetry and cyclic voltammetry methods. It also possessed a well-discrimination ability toward mismatched strands and high tolerance to complex sample matrix. The coupling of bio-gated porous nanoparticles, nuclease-assisted target amplification and catalytic redox recycling afforded the sensing system with well-controllable signal responses, sensitive and selective DNA detection, and good stability, reusability and reproducibility. It thus opens a new avenue toward the development of simple but sensitive electrochemical biosensing platform.

Abstract
A major impediment to the clinical translation of DNA tiling nanostructures is a technical bottleneck for the programmable assembly of DNA architectures with well-defined local geometry due to the inability to achieve both sufficient structural rigidity and a large framework. In this work, a Y-backbone was inserted into each face to construct a superlarge, sufficiently rigidified tetrahedral DNA nanostructure (called RDT) with extremely high efficiency. In RDT, the spatial size increased by 6.86-fold, and the structural rigidity was enhanced at least 4-fold, contributing to an ∼350-fold improvement in the resistance to nucleolytic degradation even without a protective coating. RDT can be mounted onto an artificial lipid-bilayer membrane with molecular-level precision and well-defined spatial orientation that can be validated using the fluorescence resonance energy transfer (FRET) assay. The spatial orientation of Y-shaped backbone-rigidified RDT is unachievable for conventional DNA polyhedrons and ensures a high level of precision in the geometric positioning of diverse biomolecules with an approximately homogeneous environment. In tests of RDT, surface-confined horseradish peroxidase (HRP) exhibited nearly 100% catalytic activity and targeting aptamer-immobilized gold nanoparticles showed 5.3-fold enhanced cellular internalization. Significantly, RDT exhibited a 27.5-fold enhanced structural stability in a bodily environment and did not induce detectable systemic toxicity.

Abstract
A separation platform has been developed mediated by a combination of magnetic beads and the CRISPR/Cas12a system to achieve ultrasensitive and rapid detection of miRNA-21 at a low level. In this system, with the assistance of an auxiliary probe, the target miRNA-21 can be specifically combined with three-stranded probes to initiate the SDR reaction. Abundant aptamer A3 was added to the solution that can activate the CRISPR/Cas12a system and initiate the trans-cleavage reaction to recover the fluorescence signal. Using magnetic beads to mediate the separation considerably greatly improves the signal conversion efficiency and detection sensitivity. At the 492 nm excitation wavelength, and 502-650 nm scan range, through analyzing the fluorescence peak intensity at 520 nm, the biosensor's determination range and limit of detection is 8 fM-250 nM and 2.42 fM, respectively, and the RSD is 19.03-37.80. Compared with other biosensors, the biosensor developed exhibited superior performance and the signal recovered excellently in 1% human serum and the LOD is 12.12 fM. This method provides a novel highly sensitive scheme for detecting miRNA .

Abstract
Membrane protein dimerization regulates numerous cellular biological processes; therefore, highly sensitive and facile detection of membrane protein dimerization are very crucial for clinical diagnosis and biomedical research. Herein, a colorimetric detection of Met dimerization on live cells via smartphone for high-sensitivity sensing of the HGF/Met signaling pathway was developed for the first time. The Met monomers on live cells were recognized by specific ligands (aptamers) first, and the Met dimerizations triggered the proximity-ligation-assisted catalytic hairpin assembly (CHA) reaction to generate large amounts of G-quadruplex (G4) fragments which can further combine hemin to form G4/hemin DNAzymes possessing the horseradish-peroxidase-like catalytic activity for catalyzing the oxidation of ABTS by H2O2 and producing the colorimetric signal (i.e., color change). The colorimetric detection of Met on live cells was then achieved by image acquisition and processing via a smartphone. As a proof-of-principle, the HGF/Met signaling pathway based on Met-Met dimerization was facile monitored, and the human gastric cancer cells MKN-45 with natural Met-Met dimers were sensitively tested and a wide linear working range from 2 to 1000 cells with a low detection limit of 1 cell was obtained. The colorimetric assay possesses a good specificity and high recovery rate of MKN-45 cells spiked in peripheral blood, which indicates that the proposed colorimetric detection of Met dimerization can be used for convenient observation of the HGF/Met signaling pathway and has extensive application prospects in point-of-care testing (POCT) of Met-dimerization-related tumor cells.

Abstract
As an important tumor suppressor gene, the p53 gene is considered to be a typical biomarker for the early diagnosis and prognosis evaluation of severe cancer. Herein, an electrochemical biosensor was proposed for the ultrasensitive detection of the p53 gene based on molecular beacon-mediated circular strand displacement polymerization combined with terminal deoxynucleotide transferase-mediated template-free DNA extension. Firstly, the p53 gene opened the hairpin structure of the molecular beacon, thereby exposing the binding sequence region of the primer DNA. The circular strand displacement polymerization occurred in the presence of the primer DNA and phi29 DNA polymerase, subsequently resulting in the circulation of the p53 gene. With the catalysis of the terminal deoxynucleotide transferase, the 3'-OH terminal sequence of the molecular beacon elongated to produce long single-stranded DNA under the template-free DNA extension. Methylene blue bound with such DNA strands generated a strong differential pulse voltammetry (DPV) signal with a peak potential of -0.28 V. Under the optimal detection conditions, the DPV signal of methylene blue showed good linear relationships with the logarithm value of the p53 gene in two concentration ranges of 0.05 fM to 3 pM and 5 fM to 100 fM, and the detection limit of the p53 gene was as low as 0.018 fM. This electrochemical biosensor possessed high recognition ability for the p53 gene in its analogues and was successfully applied for p53 gene analysis in human serum samples.

Abstract
Sensitive and reliable detection of the p53 gene plays a significant role in precise cancer targeting and in fundamental research. However, the sensitivity of existing p53 gene detection approaches remains to be improved. Herein, we develop a target recognition assisted-primer exchange reaction (Ta-PER) for sensitive analysis of the p53 gene. Ta-PER was initiated by the recognition of a designed dumbbell structure probe by the p53 gene. In Ta-PER, the primer exchange reaction (PER) was combined with molecular beacon-based chain recycling to construct the signal amplification process. Through integrating target recognition with PER-based signal amplification, Ta-PER was established and exhibited a high detection sensitivity, with a limit of detection as low as 56 fM. In addition, the approach was also used to detect the p53 gene in normal HeLa cells and amatoxin-treated HeLa cells. The high level of the p53 gene in amatoxin-treated HeLa cells, which was approximately 1.67 times higher than that in HeLa cell extract, indicated the apoptosis of cells and suggested the promising prospect of the approach.

Abstract
It remains technically challenging to develop a sensitive assay system to isothermally amplify the signal for miRNA detection because of its low abundance in tested sample, sequence similarities and existence in complex biological environments. In this study, using miRNA-21 as target model, a hairpin-inserted cross-shaped DNA nanoprobe (CP) with four functional arms is constructed for the ultrasensitive detection of miRNA via one-step built-in target analogue (BTA) cycle-mediated signal amplification. BTA is pre-locked in one arm of CP probe and inactive. In the presence of target miRNA, BTA can be unlocked and initiate an isothermal amplification process. Utilizing as-designed CP probe, miRNA-21 can be detected to down to 500 fM, and the linear response range spans over five orders of magnitude. The nonspecific signal is less than 1% upon nontarget miRNAs. CP probe exhibits ∼six times enhancement in resistance to nuclease degradation and no obvious degradation-induced fluorescence change is detected during the assay period. The recovery yield ranges from 98.2~105.5% in FBS solution. Because of the high sensitivity, desirable specificity, strong anti-interference ability and substantial increase in nuclease resistance, CP probe is a promising tool for the detection of miRNAs in a complex biological milieu.

Abstract
Design of oligonucleotide probe-based isothermal amplification with the ability to identify miRNA biomarkers is crucial for molecular diagnostics. In this work, we engineered a miRNA-21-responsive G-quadruplex-embedded self-quenching probe (GE-SQP) that can regulate single probe-based multiplex amplifications. The free GE-SQP is tightly locked in a quenching state with no active G-quadruplexes. Introduction of target miRNA to hybridize with GE-SQP would induce a multiplex isothermal amplification to significantly build a lot of one-bulb-contained road lamp probe (OC-RLP) and two-bulb-contained road lamp probe (TC-RLP) using G-quadruplex as the lamp bulb. When lightened by thioflavin T (ThT), beams of fluorescence were emitted to show the presented miRNA-21. Specially, the whole amplification is only a one probe-involved one-step reaction without any wasted species. The mix-to-detection and all-in amplification behavior allows the sensing system a maximally maintained operation simplicity and high assay performance. In such a way, the detection range of miRNA-21 is from 1 fM to 1 nM with a limit of detection of 0.86 fM. The practicability was demonstrated by determining miRNA-21 from serum samples with acceptable results. We expect that this method can open a new avenue for exploring advanced biosensors with improved analytical performances.

Abstract
The sensing of intracellular microRNAs (miRNAs) is of significance for early-stage disease diagnosis and therapeutic monitoring. DNA is an interesting building material that can be programed into assemblies with rigid and branched structures, especially suitable for imaging intracellular biomolecules or therapeutic drug delivery. Here, by introducing the palindromic sequences into the programmable DNA hairpins, we describe an endogenous target-responsive three-way branched and palindrome-assisted catalytic hairpin assembly (3W-pCHA) approach for imaging miRNA-155 of living tumor cells with high sensitivity. The miRNA-155 triggers autonomous assembly of the fluorescently quenched signal hairpin and two hairpin dimers formed via hybridization of their respective palindromic sequences to yield branched DNA junctions, which carry the unopened hairpins and thus provide addressable substrates for continuous assembly formation of DNA nanostructures. During the formation of the DNA nanostructures, the miRNA-155 is cyclically reused and many signal probes are unfolded to show highly intensified fluorescence for detecting miRNA-155 down to 6.9 pM in vitro with high selectivity. More importantly, these probes can be transfected into live cancer cells to initiate the assembly process triggered by intracellular miRNA-155, which provides a new way for imaging highly under-expressed miRNAs in cells. Besides, this approach can also be employed to differentiate miRNA-155 expression variations in different cells, indicating its promising potentials for early-stage disease diagnosis and biological studies in cells.

Abstract
Nuclease-resistant assay probes are of significant importance for biochemical analysis and disease diagnosis. In this contribution, a reconfigurable lipidic moiety-attached DNA nanoparticle (LDN) is constructed from a cholesterol-conjugated multifunctional hairpin-type DNA probe (Chol-DP) by hydrophobicity-mediated self-assembly. The LDN holds high serum stability and displays a low false-positive signal even in a complex biological milieu. The hydrophobic cholesterol moiety enables the hydrophobicity-mediated assembly, while hydrophilic DNA sequence serves as a recognition element and a polymerization template. The initiator-activated strand displacement amplification (SDA) reaction can convert the hairpin-shaped probe into rigid double-stranded DNA (dsDNA), causing the conformational rearrangement-based LDN swelling that can be used to reliably and fluorescently signal the cancer-related p53 gene. The size increase and structural reconfiguration are confirmed by dynamic light scattering (DLS) analysis and confocal microscopy imaging, respectively. Target p53 is specifically detected down to 10 pM. The whole assay process involved only several simple mixing steps. Recovery test and blind test further confirm the feasibility of the use of the LDN for the detection of target DNA in a complex biological milieu, indicating a promising nanotool for biomedical applications.

Abstract
DNA nanotechnology is often used to build various nano-structures for signaling and/or drug delivery, but it essentially suffers from several major limitations, such as a large number of DNA strands and limited targeting ligands. Moreover, there is no report on in vivo two-dimensional DNA arrays because of various technical challenges. By cross-catenating two palindromic DNA rings, herein, we demonstrate a catenane-based grid-patterned periodic DNA monolayer array ([2]GDA) capable of preferentially accumulating in tumor tissues without any targeting ligands, with a thickness equal to the double-helical DNA monolayer (nearly 2 nm). The structural flexibility of [2]GDA enabled it to fold into a spherical object in solution, favoring cellular uptake. Thus, its cellular internalization activity was comparable with that of the commercial lipofectamine 3000. Moreover, [2]GDA retained the structural integrity over 24 h incubation in biological solutions, achieving a 360-fold improvement in in vivo stability. Significantly, anticancer drug-loaded [2]GDA exhibits desirable therapeutic efficacy in tumor-bearing animals without detectable side effects.

Abstract
Sensitive and selective detection of proto-oncogenes, especially recognition of point mutation, is of great importance in cancer diagnosis. Here, a ligation-mediated technique is demonstrated for the construction of an intertwined three-dimensional DNA nanosheet (3D SDN) on an electrode surface from only two palindromic hairpin probes (HP1 and HP2), creating a powerful electrochemical biosensor (E-biosensor) for the detection of the p53 gene. First, a capturing probe (CP) is immobilized on an electrode surface via Au-S chemistry, forming an electrochemical sensing interface. In the presence of the target p53 (T), the triggering probe is covalently linked to CP by a ligase. Moreover, target hybridization/ligation/dehybridization process is repeated, amplifying the target hybridization event and increasing the content of surface-confined triggering fragments. As a result, HP1 is opened and in turn interacts with HP2, forming intertwined 3D SDN where HP1 and HP2 are alternately arranged in parallel. Common hybridization and interaction between palindromic fragments are responsible for the assembly in the horizontal and vertical directions, respectively. An electrochemical indicator, methylene blue (MB), can be inserted into 3D SDN, generating a strong electrochemical signal. Utilizing the 3D SDN-based E-biosensor, the target DNA is detected down to 3 fM with a linear response range from 10 fM to 10 nM. Single point mutations are reliably identified even in fetal bovine serum and cellular homogenate. Because of the several advantages of simple design, good universality, inexpensive instrumentation, high assay specificity, and sensitivity, the 3D SDN-based E-biosensor is expected to provide a potential platform for screening point mutation required by early clinical diagnostics and medical research.

Abstract
A versatile organic room-temperature phosphorescence (RTP)-based "turn on" biosensor platform has been devised with high sensitivity by combining oxygen-sensitive lipid-polymer hybrid RTP nanoparticles with a signal-amplifying enzymatic oxygen scavenging reaction in aqueous solutions. When integrated with a sandwich-DNA hybridization assay on 96-well plates, our phosphorimetric sensor demonstrates sequence-specific detection of a cell-free cancer biomarker, a TP53 gene fragment, with a sub-picomolar (0.5 p.m.) detection limit. This assay is compatible with detecting cell-free nucleic acids in human urine samples. Simply by re-programming the detection probe, our unique methodology can be adapted to a broad range of biosensor applications for biomarkers of great clinical importance but difficult to detect due to their low abundance in vivo.

Abstract
As a kind of cell-free DNA in the bloodstream liberated from tumor cells, circulating tumor DNAs (ctDNAs) have been recognized as promising biomarkers in the field of early cancer diagnosis. However, robust, sensitive, and accurate detection of ctDNA in serum remains extremely challenging, especially toward the mutant KRAS gene, one of the most frequently mutated genes. Although DNA oligonucleotides as emerging practical signaling materials have been developed as sensitive and accurate tools, some intrinsic defects need to be overcome, such as fragility in complex biological environments. In this work, on the basis of the hydrophilicity-promoted assembly, a core/shell DNA nanostructure (DNS-MB) probe is constructed from only one hairpin-shaped probe (cholesterol-modified palindromic molecular beacon, Chol-PMB) for the amplification detection of KRAS mutation in serum without the need for any auxiliary probe. Chol-PMB is designed to recognize target DNA and serve as a polymerization primer and template, and thus target species can initiate polymerization-based strand displacement amplification (SDA). Moreover, target DNA is able to induce further aggregation of DNS-MB particles due to the enzymatic cross-linking effect, leading to a structural upgrade. The DNS-MB probe exhibits a detection limit of 50 fM and a wide quantitative range (from 50 fM to 160 nM). In addition, single nucleotide polymorphisms can be discriminated, such as mutant KRAS G12D (KRAS-M), providing a desirable platform for screening ctDNAs. More excitingly, because the termini of DNA components are hidden inward from nuclease attack, DNS-MB circumvents a false-positive signal even in freshly sampled serum and is suitable for application in the complex biological milieu. As a proof of concept, the DNS-MB probe is expected to provide useful insight into the development of simple and degradation-resistant DNA probes for substantially amplified detection of ctDNAs in complex serum, showing potential applications in the field of early tumor diagnosis.

Molecules 2021; 26:molecules26216432. [PMID: 34770841 PMCID: PMC8588017 DOI: 10.3390/molecules26216432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 10/20/2021] [Accepted: 10/23/2021] [Indexed: 11/16/2022] Open
Abstract
MicroRNA160 plays a crucial role in plant development by negatively regulating the auxin response factors (ARFs). In this manuscript, we design an automatic molecule machine (AMM) based on the dual catalytic hairpin assembly (D-CHA) strategy for the signal amplification detection of miRNA160. The detection system contains four hairpin-shaped DNA probes (HP1, HP2, HP3, and HP4). For HP1, the loop is designed to be complementary to miRNA160. A fragment of DNA with the same sequences as miRNA160 is separated into two pieces that are connected at the 3′ end of HP2 and 5′ end of HP3, respectively. In the presence of the target, four HPs are successively dissolved by the first catalytic hairpin assembly (CHA1), forming a four-way DNA junction (F-DJ) that enables the rearrangement of separated DNA fragments at the end of HP2 and HP3 and serving as an integrated target analogue for initiating the second CHA reaction, generating an enhanced fluorescence signal. Assay experiments demonstrate that D-CHA has a better performance compared with traditional CHA, achieving the detection limit as low as 10 pM for miRNA160 as deduced from its corresponding DNA surrogates. Moreover, non-target miRNAs, as well as single-base mutation targets, can be detected. Overall, the D-CHA strategy provides a competitive method for plant miRNAs detection.

Abstract
In this work, a simple and ultrasensitive colorimetric biosensor for detection of SURF1 gene fragments (Leigh syndrome) has been developed based on a dual DNA-induced cascade hybridization reaction. Firstly, a biotin labeled capture probe was immobilized on a streptavidin labeled 96-well transparent plate surface. Then the target SURF1 fragment and auxiliary probe S1 were added into the reaction system to form a "Y" structure with the capture probe. Furthermore, to achieve a highly efficient signal amplification strategy, digoxin labeled P1, P2, P3 and P4 probes were used to cause a dual DNA-induced cascade hybridization reaction on the "Y" structure of the 96-well plate surface. As a detection probe, the HRP anti-digoxin antibody was combined on the surface to produce a colorimetric response to the SURF1 fragment in the presence of TMB. Under the optimal conditions, the established method exhibited a wide linear range from 1.0 × 10-13 M to 1.0 × 10-8 M and a detection limit to SURF1 as low as 1.73 × 10-14 M. In addition, the strategy has been successfully applied to the detection of SURF1 in spiked human serum samples. Therefore, the established biosensor has potential application prospects in gene fragment analysis and early diagnosis of clinical diseases.

Abstract
DNA-based amplifiers with high programmability and accurate molecular recognition ability have become a versatile platform for target amplification. However, the random diffusion of capture probes (CPs) in most DNA amplifiers limits the target recognition efficiency, affecting the limit of detection. Herein, a high-efficient DNA amplifier was developed by localizing the CPs consisted of the unique palindromic tails and target recognition sequences on Au nanoparticle modified magnetic beads (Au@MBs). In the presence of target K-ras gene, the CPs with high local concentration and orientation could capture the target efficiently to expose their palindromic tails, which could act as primers to trigger the polymerization for target recycling. More importantly, the polymerization products could involve in the next recycle and produce abundant mimic targets (MTs) continuously, thereby achieving the detection of trace K-ras gene. Meanwhile, a novel electrochemiluminescence (ECL) indicator of a thin-layer of perylene (Pe) molecules decorated Ag microflowers (Pe@Ag MFs) was obtained based on the reaction between the perylene cation radical (Pe•+) and Ag atoms. The obtained Pe@Ag MFs exhibited desirable ECL performance because (i) a thin-layer of Pe molecules could reduce the inner filter effect and inactive emitters, (ii) the Ag MFs as coreaction accelerator could react with S2O82- to produce more SO4•- and shorten the distance between Pe•- and SO4•- to significantly enhance the ECL intensity of Pe with less energy loss. This work paves the way for the development of efficient amplification strategy and offers a paradigm for the preparation of high-efficiency ECL indicators.

Abstract
Biochemical properties and flexibility of nitrogenous bases allow DNA to fold into higher-order structures. Among different DNA secondary structure, G-quadruplexes (tetrapelexes-G4) - which are formed in guanine rich sequences - have gained more attention because of their biological significance, therapeutic intervention, and application in molecular device and biosensor. G4-quadruplex studies categorize into three main fields, in vivo, in vitro, and in silico. The in vitro field includes G4 synthetic oligonucleotides. This review focuses on the G-quadruplex synthetic aptamers structure features and considers the applicability of G4-aptamers for cancer biomarkers detection. Various biosensing methods will be reviewed based on G-quadruplex aptamers for cancer detection.

Abstract
In view of the high sensitivity and good selectivity, chemical vapor generation atomic spectrometry (CVG-AS) and inductively coupled plasma mass spectrometer (ICP-MS), especially low-cost atomic fluorescence spectrometry (AFS) have been widely used in bioassay. However, the existing AS method is mostly based on heterogeneous strategies, and can't detect multiple targets in one system. In this study, we present the discovery and mechanism study of a phenomenon of Hg2+ pre-reduction that the concentration of Hg2+ decreased when it was mixed with the reductants (ascorbic acid (AA), SnCl2, or NaBH4/KBH4) over long-time reaction (hours) by CVG-AFS and ICP-MS. A homogeneous Cu2+ assay method was developed based on the competition reaction of Cu2+ and Hg2+ for consuming AA, and its application in the detection of pyrophosphate (PPi) and alkaline phosphatase (ALP) was investigated based on the PPi complexation with Cu2+, and ALP hydrolyzation of PPi using CVG-AFS as a representative detector. Subsequently, in order to further verify the applicability of the system, cation exchange reaction (CER) was utilized here based on the selectively recognize Ag+ and C-Ag+-C by CuS nanoparticles (NPs). As the exchanged Cu2+ from CuS NPs can be sensitively and selectively detected via above-mentioned Cu2+ assay method, this strategy can be extended for the Ag+, DNA and prostate specific antigen (PSA) detection based on base complementary pairing and the specific recognition of aptamer. Under the optimal experimental conditions, the system showed high sensitivity for the detection of Cu2+, PPi, ALP, Ag+, DNA, and PSA, with limit of detections (LODs) of 0.12 nmol L-1, 25 μmol L-1, 0.025 U/L, 0.2 nmol L-1, 0.05 nmol L-1, and 0.03 ng/mL, respectively. The method was successfully used to determination Cu2+, ALP, and PSA in human serums, showing similar results with those of ICP-MS and kits methods.

Abstract
In this work, a simple but sensitive electrochemical DNA biosensor for nucleic acid detection was developed by taking advantage of exonuclease (Exo) I-assisted cleavage for background reduction and zirconia-reduced graphene oxide-thionine (ZrO2-rGO-Thi) nanocomposite for integral DNA recognition, signal amplification, and reporting. The ZrO2-rGO nanocomposite was obtained by a one-step hydrothermal synthesis method. Then, thionine was adsorbed onto the rGO surface, via π-π stacking, as an excellent electrochemical probe. The biosensor fabrication is very simple, with probe DNA immobilization and hybridization recognition with the target nucleic acid. Then, the ZrO2-rGO-Thi nanocomposite was captured onto an electrode via the multicoordinative interaction of ZrO2 with the phosphate group on the DNA skeleton. The adsorbed abundant thionine molecules onto the ZrO2-rGO nanocomposite facilitated an amplified electrochemical response related with the target DNA. Since upon the interaction of the ZrO2-rGO-Thi nanocomposite with the probe DNA an immobilized electrode may also occur, an Exo I-assisted cleavage was combined to remove the unhybridized probe DNA for background reduction. With the current proposed strategy, the target DNA related with P53 gene could be sensitively assayed, with a wide linear detection range from 100 fM to 10 nM and an attractive low detection limit of 24 fM. Also, the developed DNA biosensor could differentiate the mismatched targets from complementary target DNA. Therefore, it offers a simple but effective biosensor fabrication strategy and is anticipated to show potential for applications in bioanalysis and medical diagnosis.

Abstract
A novel fluorescence sensing strategy for ultrasensitive and highly specific detection of adenosine triphosphate (ATP) has been developed by the combination of the proximity ligation assay with bidirectional enzymatic repairing amplification (BERA). The strategy relies on proximity binding-triggered the release of palindromic tail that initiates bidirectional cyclic enzymatic repairing amplification reaction with the aid of polymerase and two DNA repairing enzymes, uracil-DNA glycosylase (UDG) and endonuclease IV (Endo IV). A fluorescence-quenched hairpin probe with a palindromic tail at the 3' end is skillfully designed that functions as not only the recognition element, primer, and polymerization template for BERA but also the indicator for fluorescence signal output. On the basis of the amplification strategy, this biosensor displays excellent sensitivity and selectivity for ATP detection with an outstanding detection limit of 0.81 pM. Through simultaneously enhancing the target response signal value and reducing nonspecific background, this work deducted the background effect, and showed high sensitivity and reproducibility. Moreover, our biosensor also shows promising potential in real sample analysis. Therefore, the proximity-enabled BERA strategy indeed creates a simple and valuable fluorescence sensing platform for ATP identification and related disease diagnosis and biomedical research.

Abstract
Gold nanoparticle-core spherical nucleic acids (AuNP core-SNAs), by virtue of the programmable nature of oligonucleotides, have yielded access to the innovative strategies for targeted biodiagnostics. Here, DNA-directed self-assembly of AuNP core-SNAs has been used to design a colorimetric method to sense HIV-1 viral nucleic acid. This strategy utilizes an oligonucleotide with sequence of 5'-untranslated region (5' UTR) of the HIV-1 RNA genome anchored on the surface of AuNPs and a complementary linker strand with a palindromic sequence tail. In the absence of HIV-1 target nucleic acid the complementary linker induces self-assembly of SNAs based on sequence symmetry in the free palindromic tail which can bridge two DNA double helices. While in the presence of the target DNA, due to linker-target duplex formation, the colloidal stability and the red color of the SNAs solution are preserved. Picomole amounts of target DNA can easily be detected with the naked eyes. A 95-mer synthetic DNA strand with the same sequence of HIV-1 viral RNA was utilized for positive control of HIV-1 RNA. The selectivity of the selected linker was satisfactory up to 90% match.

Abstract
Epigenetic inheritance is a heritable change in gene function independent of alterations in nucleotide sequence. It regulates the normal cellular activities of the organisms by affecting gene expression and transcription, and its abnormal expression may lead to the developmental disorder, senile dementia, and carcinogenesis progression. Thus, epigenetic inheritance is recognized as an important biomarker, and the accurate quantification of epigenetic inheritance is crucial to clinical diagnosis, drug development and cancer treatment. Noncoding RNA, DNA methylation and histone modification are the most common epigenetic biomarkers. The conventional biosensors (e.g., northern blotting, radiometric, mass spectrometry and immunosorbent biosensors) for epigenetic biomarkers assay usually suffer from hazardous radiation, complicated manipulation, and time-consuming procedures. To facilitate the practical applications, some new biosensors including colorimetric, luminescent, Raman scattering spectroscopy, electrochemical and fluorescent biosensors have been developed for the detection of epigenetic biomarkers with simplicity, rapidity, high throughput and high sensitivity. In this review, we summarize the recent advances in epigenetic biomarkers assay. We classify the biosensors into the direct amplification-free and the nucleotide amplification-assisted ones, and describe the principles of various biosensors, and further compare their performance for epigenetic biomarkers detection. Moreover, we discuss the emerging trends and challenges in the future development of epigenetic biomarkers biosensors.

Abstract
DNA tetrahedron-modified silver nanoparticles (AgNPs) were achieved via amino-silver chemistry for the first time and were applied as a colorimetric biosensor for detecting HIV-related DNA. Target DNA initiated strand displacement polymerization and nicking endonuclease-aided cycles were involved to link DNA tetrahedron-modified AgNPs, reporting colorimetric responses. This developed method showed excellent specificity and sensitivity. A wide linear range from 1 to 15 000 nM was achieved with a limit of detection of 0.84 nM. Moreover, it was successfully applied to determine DNA in blood serum samples.

Abstract
This work presented an innovative and rationally engineered palindromic molecular beacon (PMB) based "Z-scheme" photoelectrochemical (PEC) biosensing protocol for the selective screening of kanamycin (Kana) through DNA hybridization-induced conformational conversion. Interestingly, the ingeniously designed PMB integrated the multifunctional elements including recognition region, primer-like palindromic fragment, and polymerization-nicking template. The cosensitized structures consisted of CdS quantum dot functionalized hairpin DNA2 (QD-HP2) and region-selectively deposited gold nanoparticles onto {001} facets of bismuth oxychloride (BiOCl-Au). Compared with BiOCl-Au alone, the attachment of CdS QDs onto BiOCl-Au (i.e., BiOCl-Au-CdS QDs) exhibited evidently enhanced photocurrent intensity thanks to the synergistic effect of Z-scheme BiOCl-Au-CdS QDs. After incubation with target Kana, Kana-aptamer binding could induce the exposure of PMB region for hairpin DNA1 (HP1). The exposed palindromic tails hybridized with each other (like a molecular machine) to consume the substrates (dNTPs) and fuels (enzyme) for the releasing of numerous nick fragments (Nick). The as-generated nick fragments could specifically hybridize with the complementary region of QD-HP2, thus resulting in decreasing photocurrent because of the increasing spatial distance for electron transfer between two-type photosensitizers. Under optimum conditions, the PMB-based sensing system exhibited satisfying photocurrent responses toward target Kana within the working range from 50 to 5000 fM at a low detection limit of 29 fM. Impressively, the concept of a palindromic fragment-mediated primer-free biosensing strategy offers a new avenue for advanced development of efficient and convenient biodetection systems.

Abstract
Mutation of p53 tumor suppressor gene represents one of the early molecular events in tumor initiation and progression. Although molecular computing holds tremendous potential with important applications in diagnosis, prognosis and treatment of human diseases at the molecular level, designing molecular logic gates to implement cascade amplification via operating autonomously for the detection of point mutations still remains challenging. In this contribution, we developed a three concatenated logic gates (TCLG) to perform multiple strand displacement amplification (m-SDA) for screening the cancer-related point mutations only via designing an innovative molecular beacon (MB). Specifically, using p53 gene as model target, extending the two ends of a MB via adding two fragments with the same sequence achieves two unique terminal single-stranded (ss) overhangs. After self-folding of MB into hairpin structure, the two overhangs exhibit a near inverted mirror image (IM) relationship if taking the base nature and direction into account. For this, the probe is called IM-MB. Because cascade SDAs can occur on IM-MB and promote each other, the target gene can be detected down to 10 pM. Along this line, the TCLG circuit was proposed, and two primers and target gene serve as the indispensable input signals. Utilizing this logic circuit, the point mutation or absence of target gene can be sensitively screened. Moreover, its potential application in the recognition of point mutations in complex biomatrix has been demonstrated via blind test. The proof-of-concept scheme is expected to provide new insight into the development of DNA-based molecular logic gates and their applications in basic research, medical diagnosis and precise treatment and treatment of genetic diseases.

Abstract
In this study, a biosensing system based on nicking-enhanced rolling circle amplification (N-RCA) was proposed for the highly sensitive detection of cancer-related let-7a microRNA (miRNA). The sensing system consists of a padlock probe (PP), which contains a target recognition sequence and two binding sites for nicking endonuclease (NEase), and molecular beacon (MB) as reporting molecule. Upon hybridization with let-7a, the PP can be circularized by ligase. Then, the miRNA acted as polymerization primer to initiate rolling circle amplification (RCA). With the assistance of NEase, RCA products can be nicked on the cyclized PP and are displaced during the subsequent duplication process, generating numerous nicked fragments (NFs). These NFs not only induce another RCA reaction but also open the molecular beacons (MBs) via hybridization, leading to significantly amplified fluorescence signal. Under the optimized conditions, this method exhibits high sensitivity toward target miRNA let-7a with a detection limit of as low as 10 pM, a dynamic range of three orders of magnitude is achieved, and its family member is easily distinguished even with only one mismatched base. Meanwhile, it displays good recovery and satisfactory reproducibility in fetal bovine serum (FBS). Therefore, these merits endow the newly proposed N-RCA strategy with powerful implications for miRNA detection.

Abstract
Taking advantage of the homogeneous and heterogeneous electrochemical biosensors, a simple, sensitive, and selective electrochemical biosensor is constructed by combining entropy-driven amplification (EDA) with DNA walker. This electrochemical biosensor realizes the biorecognition and EDA operation in homogeneous solution, which is beneficial to improve the recognition and amplification efficiency. A two-leg DNA walker generated by EDA can walk on the surface of gold electrode for cleaving the immobilized substrate DNA and releasing the electroactive labels, giving rise to a significant decrease of the electrochemical signal. The immobilization of the electroactive labels ensures the reproducibility and reliability of the biosensor. The present cascade amplification assay can be applied to detect target DNA with a detection limit of 0.29 fM, and base mutations can be easily distinguished. Moreover, the proposed electrochemical biosensor shows a satisfactory performance for the detection of target DNA in human serum. Thus, the novel electrochemical biosensor holds promising potential for a future application in disease diagnosis.
