Abstract
Biosensors have emerged as ideal analytical devices for various bio-applications owing to their low cost, convenience, and portability, which offer great potential for improving global healthcare. DNA self-assembly techniques have been enriched with the development of innovative amplification strategies, such as dispersion-to-localization of catalytic hairpin assembly, and dumbbell hybridization chain reaction, which hold great significance for building biosensors capable of realizing sensitive, rapid and multiplexed detection of pathogenic microorganisms. Here, focusing primarily on the signal amplification strategies based on DNA self-assembly, we concisely summarized the strengths and weaknesses of diverse isothermal nucleic acid amplification techniques. Subsequently, both single-layer and cascade amplification strategies based on traditional catalytic hairpin assembly and hybridization chain reaction were critically explored. Furthermore, a comprehensive overview of the recent advances in DNA self-assembled biosensors for the detection of pathogenic microorganisms is presented to summarize methods for biorecognition and signal amplification. Finally, a brief discussion is provided about the current challenges and future directions of DNA self-assembled biosensors.

Abstract
The working efficiency of traditional 3D DNA nanomachines is extremely restricted due to the complex DNA components modified on nanoparticles in the same spatial height. Herein, an ultrafast dual-layer 3D DNA nanomachine (UDDNM) based on catalytic hairpin assembly (CHA) was developed by assembling two different lengths of hairpin DNA on the surface of gold nanoparticles, the long hairpin 1 (H1), to capture the trigger, and the short hairpin 2 (H2), as the signal probe, to recycle the trigger. Compared to the traditional single-layer 3D DNA nanomachine, the dual-layer 3D DNA nanostructure greatly enhances the effective collision between trigger and targeted DNA probe, H1, since the H1 located in outer layer would react with the trigger, inhibiting the invalid collision between the trigger and residual DNA component, H2, and remarkably decreasing the steric hindrance associated with the nucleic acids layer around the nanoparticles. Especially, when the distance of two layers was fixed at 3 nm, the corresponding UDDNM could accomplish the overall reaction only in 3 min with a dramatically high initial rate of up to 5.93 × 10-7 M s-1, which was at least 5-fold beyond that of the typical single-layer 3D DNA nanomachines. As a proof of concept, the described UDDNM was successfully applied in ultrasensitive fluorescence detection and sensitive intracellular imaging of miRNA-21. Consequently, our strategy, based on the creation of dual-layer 3D DNA nanostructure, may create a new approach to designing the next generation of DNA nanomachine and has enormous potential for applications in bio-analysis, logic gate operations, and clinical diagnoses.

Abstract
The catalytic hairpin-rigidified Y-shaped DNA through layer-by-layer assembly has been fixed on the surface of copper sulfide nanoparticles for the detection of survivin mRNA. The distance between the CHA probes fixed on the Y-shaped DNA is significantly shortened. The results show that the fluorescence of this nanomachine reached the maximum value in 50 min (excitation wavelength at 488 nm and emission wavelength 526 nm), and its reaction rate is more than 5-fold faster than that of the free-CHA control system. In addition, the nanomachine showed high sensitivity (LOD of 3.5 pM) and high specificity for the survivin mRNA detection. Given its fast response time and excellent detection performance, we envision that the catalytic hairpin-rigidified Y-shaped DNA-functionalized nanomachine will offer potential applications in disease diagnostics and clinical applications.

Abstract
Extracellular vesicles (EVs) have emerged as a novel resource of biomarkers for cancer and certain other diseases. Probing EVs in body fluids has become of major interest in the past decade in the development of a new-generation liquid biopsy for cancer diagnosis and monitoring. However, sensitive and specific molecular detection and analysis are challenging, due to the small size of EVs, low amount of antigens on individual EVs, and the complex biofluid matrix. Nanomaterials have been widely used in the technological development of protein and nucleic acid-based EV detection and analysis, owing to the unique structure and functional properties of materials at the nanometer scale. In this review, we summarize various nanomaterial-based analytical technologies for molecular EV detection and analysis. We discuss these technologies based on the major types of nanomaterials, including plasmonic, fluorescent, magnetic, organic, carbon-based, and certain other nanostructures. For each type of nanomaterial, functional properties are briefly described, followed by the applications of the nanomaterials for EV biomarker detection, profiling, and analysis in terms of detection mechanisms.

Abstract
DNAzyme motor systems using gold nanoparticles (AuNPs) as scaffolds are useful for biosensing and in situ amplification because these systems are free of protein enzymes, isothermal, homogeneous, and sensitive. However, detecting different targets using the available DNAzyme motor techniques requires redesigns of the DNAzyme motor. We report here a toehold-exchange translator and the translator-mediated DNAzyme motor systems, which enable sensitive responses to various nucleic acid targets using the same DNAzyme motor without requiring redesign. The translator is able to efficiently convert different nucleic acid targets into a specific output DNA that further activates the pre-silenced DNAzyme motor and consequently initiates the autonomous walking of the DNAzyme motor. Simply adjusting the target-binding region of the translator enables the same DNAzyme motor system to respond to various nucleic acid targets. The translator-mediated DNAzyme motor system is able to detect as low as 2.5 pM microRNA-10b and microRNA-21 under room temperature without the need of separation or washing. We further demonstrate the versatility of the translator and the DNAzyme motor by successful construction and operation of four logic gates, including OR, AND, NOR, and NAND logic gates. These logic gates use two microRNA targets as inputs and generate amplified fluorescence signals from the operation of the same DNAzyme motor. Incorporation of the toehold-exchange translator into the DNAzyme motor technology improves the biosensing applications of DNA motors to diverse nucleic acid targets.

Abstract
In this work, an intelligent multiregion linear DNA walker (MLDW) with a high walking rate and a high amplification efficiency was explored for ultrasensitive detection of miRNA. Significantly, amounts of functional domain could be concentrated in a long linear DNA obtained by the target miRNA-mediated rolling-circle amplification to simultaneously increase the local concentration and collision probability, resulting in an obviously improved reaction rate. Impressively, the MLDW can accomplish the reaction within 30 min, which is at least 4 times beyond that of traditional single-leg and multiple-leg DNA walkers. As a proof of concept, the high-efficiency MLDW was used to develop an electrochemical biosensing platform for ultrasensitive detection of target miRNA-21 with a low detection limit down to 36 aM. Therefore, the MLDW we designed puts forward an innovative insight to construct a functional DNA nanodevice and promote the investigation of the inherent performance of nucleic acid signal amplification for ultimate application in the detection of biomolecules and clinical disease diagnosis.

Abstract
Enzyme-free DNA amplifiers can amplify the signal of nucleic acid molecules. They can be applied to DNA molecular operation and nucleic acid detection. The reaction speed is the core index to evaluate DNA amplifiers. In this study, we designed a DNA amplifier based on an enzyme-free chain reaction. This DNA amplifier can release one more signal molecule in each round of reaction and trigger the next round, which significantly improved reaction speed. Moreover, because the amplifier used a stable DNA structure, the reaction can occur at room temperature. To integrate the amplifier into other DNA molecular operations, we performed the amplification reaction in a microfluidic chip module. The results showed that the amplifier can realize real-time signal feedback at a proper input molecule concentration and reach the endpoint in 40 s, even at a low relative concentration. To apply the amplifier for nucleic acid detection, we also used a conventional fluorescent polymerase chain reaction instrument for the reaction. The results showed that the amplifier specifically detected trace DNA single-stranded molecules. To solve the leakage problem of existing amplifiers, we designed a DNA molecule as the chain reaction's inhibitor, which was crucial in controlling the reaction speed and preventing leakage. STATEMENT OF SIGNIFICANCE: Traditional amplifier strategies of enzyme-free DNA amplifiers relied on a constant number of cycling molecules to catalyze the amplifier molecules' changing structure and release fluorescent signals, which lead low reaction speed. Based on an enzyme-free chain reaction, we designed a DNA amplifier which can release one more cycling molecule in each loop and trigger the next loop and significantly improve reaction speed in this study. Our analysis on microfluidic chip module and PCR instrument verifies high sensitivity and selectivity. And this strategy of DNA amplifier realizes the control of reaction and prevents leakage. We believe that this automated amplification strategy could have great applications in vivo signal detection, imaging, and signal molecule translation.

Abstract
In the present review, numerous experimental and theoretical data describing the properties of non-canonical DNA structures (NSs) are analyzed. NSs (G-quadruplex, i-motif, hairpin, and triplex) play an important role in epigenetic processes (including the genetic variability of viruses), are prone to energetically low-cost conformational transformations and can very effectively be used in the design of nanoscale devices. Numerous experimental data have been analyzed in connection with the so-called oligonucleotides-transformers (nucleotide sequences that able to fold not only into one, but also into several NSs). These sequences were recently predicted by our calculations using automata and graph theories ("Dafna" algorithm). Possible applications of the oligonucleotides-transformers in nanoengineering and genetic editing of organisms are considered.

Abstract
Intensive applications of toxic malathion pesticides bring a vital threat to the environment and health. Hence, a credible and sensitive strategy is urgently needed for the respective detection of malathion. In this work, an aptamer-based nonenzymatic autonomous DNA walking machine was fabricated for monitoring trace malathion contamination in cells and foods. Along with the machine walking driven by malathion-triggered reaction entropy, multiple fluorescent signal outputs were thermodynamically generated for signal amplification. The proposed stable DNA nanomachine achieved satisfactory results with a detection limit of 81.9 pg L-1 for testing malathion, which could be applied to actual samples including apple juice, paddy water, and paddy soil. Furthermore, the high stability, sensitivity, and biocompatibility of the nanomachine enabled monitoring of the malathion contamination in living cells and bioaccumulation in lettuce without additional purification. Consequently, with these excellent performances, it is strongly anticipated that the DNA walking machine has tremendous potential to be extended to general platforms against pesticides to avoid malathion-contaminated agricultural production for environmental safety and human health.

Abstract
Herein, catalyzed hairpin assembly is implemented as an automated strategy, which can respond in living cells to detect specific target DNA. Using the principle of catalyzed hairpin assembly (CHA), the auxiliary chain connects the fuel and starting chain to form a triple-stranded DNA to complete such a single system. Hundreds of single systems are modified on gold nanoparticles as DNA orbitals. Through the specific recognition of base complementation, the target DNA can realize the automatic walking of the three-dimensional fluorescence machine. This is a novel walking nanomachine that has a simple structure and can independently exist in cells to achieve automatic operation.

Abstract
Herein, an amplified and renewable electrochemical biosensor was developed via bienzymatic cascade catalysis of glucose oxidase (GOx) and horseradish peroxidase (HRP), which were confined in a functional Y-shaped DNA nanostructure oriented by a dual-thiol-ended hairpin probe (dSH-HP) with a paired stem as a rigid scaffold and unpaired loop as enclosed binding platform. For proof-of-concept assay of sequence-specific biomarker DNA related to Alzheimer's disease (aDNA), GOx and redox ferrocene-modified HRP (Fc@HRP) were chemically conjugated in two enzyme strands (GOx-ES1 and Fc@HRP-ES2), respectively. The repeated recycling of aDNA was powered by the displacement of GOx-ES1 by aDNA and exonuclease III (ExoIII)-assisted cleavage reaction for amplified output of numerous GOx-ES1 as dependent transducers, together with Fc@HRP-ES2 which was simultaneously hybridized with dSH-HP to assemble this DNA structure. Rationally, the bienzymatic cascade catalysis was motivated through GOx-catalyzed glucose oxidization to in situ generate hydrogen peroxide (H2O2) and overlapped HRP-catalyzed H2O2 decomposition to promote the electron transfer, producing significantly enhanced electrochemical signal of Fc with an ultrahigh sensitivity down to 0.22 fM of aDNA. Benefited from the unique design of dSH-HP-oriented bienzymatic cascades, this one-step strategy without non-specific blockers passivation was simple and renewable, and would pave a promising avenue for sensitive electrochemical assay of biomolecules.

Abstract
DNA walkers have shown superior performance in biosensing due to their programmability to design molecular walking behaviors with specific responses to different biological targets. However, it is still challenging to make DNA walkers capable of distinguishing DNA targets with single-base differences, so that DNA walkers that can be used for circulating tumor DNA sensing are rarely reported. Herein, a flap endonuclease 1 (FEN 1)-assisted DNA walker has been proposed to achieve mutant biosensing. The target DNA is captured on a gold nanoparticle (AuNP) as a walking strand to walk by hybridizing to the track strands on the surface of the AuNP. FEN 1 is employed to report the walking events by cleaving the track strands that must form a three-base overlapping structure recognized by FEN 1 after hybridizing with the captured target DNA. Owing to the high specificity of FEN 1 for structure recognition, the one-base mutant DNA target can be discriminated from wild-type DNA. By constructing a sensitivity-enhanced DNA walker system, as low as 1 fM DNA targets and 0.1% mutation abundance can be sensed, and the theoretical detection limits for detecting the DNA target and mutation abundance achieve 0.22 fM and 0.01%, respectively. The results of epidermal growth factor receptor (EGFR) L858R mutation detection on cell-free DNA samples from 15 patients with nonsmall cell lung cancer were completely consistent with that of next-generation sequencing, indicating that our DNA walker has potential for liquid biopsy.

Abstract
Nucleic acid detection is of great importance in a variety of areas, from life science and clinical diagnosis to environmental monitoring and food safety. Unfortunately, nucleic acid targets are always found in trace amounts and their response signals are difficult to be detected. Amplification mechanisms are then practically needed to either duplicate nucleic acid targets or enhance the detection signals. Polymerase chain reaction (PCR) is one of the most popular and powerful techniques for nucleic acid analysis. But the requirement of costly devices for precise thermo-cycling procedures in PCR has severely hampered the wide applications of PCR. Fortunately, isothermal molecular reactions have emerged as promising alternatives. The past decade has witnessed significant progress in the research of isothermal molecular reactions utilizing hairpin DNA probes (HDPs). Based on the nucleic acid strand interaction mechanisms, the hairpin DNA-mediated isothermal amplification (HDMIA) techniques can be mainly divided into three categories: strand assembly reactions, strand decomposition reactions, and strand creation reactions. In this review, we introduce the basics of HDMIA methods, including the sensing principles, the basic and advanced designs, and their wide applications, especially those benefiting from the utilization of G-quadruplexes and nanomaterials during the past decade. We also discuss the current challenges encountered, highlight the potential solutions, and point out the possible future directions in this prosperous research area.

Abstract
Cancer antigen 125 (CA - 125) is an important biomarker for the diagnosis of ovarian cancer. In this paper, oligonucleotide 5'-GACAGGCCCGAAGGAATAGATAATACGACTCACTATAGGGAGACAAGAATAAACGCTCAA-3' (oligo 1) contains an aptamer of CA - 125, and was designed partly complementary to oligonucleotide 5'-CTCTCTCTCCACCTTCTTCTTTGAGCGTTTATTCTTGTCT-3' (oligo 2). Oligo 1 · oligo 2 was extended with the Klenow fragment (exo-) polymerase for further polymerase chain reaction (PCR) processes in the presence of two primers: deoxyribose nucleoside triphosphate and Taq polymerase. Single-stranded DNA was produced at two sides of the PCR product by introducing a C18 spacer into the two primers, which could hybridize with AuNPs-DNA probes, investigated by dynamic light scattering and fluorescence. The addition of CA - 125 can interrupt the hybridization between oligo 1 and oligo 2, causing the average diameter of AuNPs-DNA probes to decrease with the increase of CA-125 within the range of 5 fg mL-1 - 50 ng mL-1. The linear regression equation of this relationship was D = 430.48-49.60 log10C, with a detection limit of 1.1 fg mL-1. Fluorescein molecules were modified at the end of the forward primer. The fluorescence intensity of the PCR product can be measured simultaneously, with the fluorescence intensity increasing linearly with the logarithm of CA-125 concentration within a linear range from 10 fg mL-1 to 50 ng mL-1, with a detection limit of 1.5 fg mL-1.

Abstract
Molecular machines constructed by three-dimensional (3-D) DNA walker have emerged as a hot topic in applications such as novel biosensors, cargo delivery platforms and intracellular imaging. Herein, we first propose a lame DNA walker that can randomly and autonomously move on microsphere-based 3-D track. The stochastic lame walker has a long leg mainly responsible for persistent movement and a short leg cutting substrates rapidly. Its motion is propelled by a nicking endonuclease cleavage of hybridized DNA tracks. Kinetic and persistent study show that the lame DNA walker enables reaction equilibrium at 30 min, need a cleat domain of at least 14 nucleotides and can persistently move on 3-D tracks with an average rate of 6.467 × 10-11 M s-1. We also demonstrate that the lame walker can be used to detect target DNA in the detection range of 10 pM-5 nM with high specificity by toehold exchange mechanism. This work will further expand the performance of 3-D DNA walkers and substantially contributes to the improved understanding of DNA walking systems.

Abstract
Exosomes are a type of extracellular vesicle actively secreted by almost all eukaryotic cells. They are ideal candidates for reliable next-generation biomarkers in the early diagnosis and therapeutic response evaluation of cancer. Thus, the quantification of exosomes is crucial in facilitating clinical research and application. Compared with traditional materials, nanomaterials have better optical, magnetic, electrical, and catalytic properties due to their small size, high specific surface area, and variable structure. The incorporation of nanomaterials into sensing systems is an attractive approach towards improving sensitivity and can provide improved sensor selectivity and stability. In this paper, we summarize the progress in nanomaterial-based exosome detection methods, including electrochemical biosensors, photoelectrochemical biosensors, colorimetric biosensors, fluorescence biosensors, chemiluminescence biosensors, electrochemiluminescence biosensors, surface plasmon resonance biosensors, and surface-enhanced Raman spectroscopy biosensors. Moreover, future research directions and challenges in exosome detection methods are discussed. We hope that this article will offer an overview of nanomaterial-based exosome detection techniques and open new avenues in disease research.Graphical abstract.

Abstract
Stochastic DNA walkers capable of traversing on three-dimensional (3D) tracks have received great deal of attention. However, DNA walker-based biosensors exhibit limited amplification efficiency because of their slow walking kinetics and low processivity. Herein, by taking advantage of the high processivity of a DNA rolling machine, a sensitive ratiometric DNA nanomachine biosensor is designed. The biosensor is constructed with hairpin-loaded Au nanoparticles (NPs) (hpDNA@AuNPs) as a DNA walker and AgNCs-decorated magnetic NPs (AgNCs@MNPs) as a DNA rolling machine. In the presence of target DNA, exonuclease III (Exo III)-powered DNA walker is activated to accomplish first-stage amplification via a burnt-bridge mechanism, generating a great deal of toehold-loaded AuNPs (Toehold@AuNPs) to hybridize with magnetic nanoparticles loaded with silver-nanoclusters-labeled DNA (AgNCs@MNPs) with the assistance of Exo III. These trigger rapid rolling of AuNPs on the AgNCs@MNPs surface and release free AgNCs, converting the biological signal into a mass spectrometric signal ratio (107Ag/197Au) with detection by ICP-MS. A linear range of 0.5-500 fmol L-1 is achieved with a detection limit of 119 amol L-1 for the p53 gene. The practical applicability of the biosensor has been demonstrated in the accurate assay of the p53 gene in the human blood.

Abstract
Owing to their high programmability and modularity, autonomous enzyme-free nucleic acid circuits are attracting ever-growing interest as signal amplifiers with potential applications in developing highly sensitive biosensing techniques. Besides nucleic acid input, the biosensing scope of aptamer-integrated nucleic acids could be further expanded to non-nucleic targets by integrating nucleic acid circuits with aptamers-a class of functional oligonucleotides with binding capabilities toward specific targets. By coupling upstream target recognition with downstream signal amplification, aptamer-integrated nucleic acid circuits enable aptasensors with increased sensitivity and enhanced performances, which may act as powerful tools in various fields including environment monitoring, personal care, clinical diagnosis, etc. In designing aptamer-integrated nucleic acid circuits, smart integration between aptamer and nucleic acid circuits plays a crucial role in developing reliable circuits with good performances. To date, although there are plenty of published researches adopting aptamer-integrated nucleic acid circuits as amplifiers in biosensing systems, deep discussion or systematic review on rational design strategies for aptamer-integrated nucleic acid circuits is still lacking. To fill this gap, rational aptamer-nucleic acid circuits integration modes were classified and summarized for the first time based on reviewing the state of art of existing aptamer-integrated nucleic acid circuits. Moreover, theoretical updates in nucleic acid circuits designs and major challenges to be overcome in developing highly sensitive aptamer-integrated nucleic acids based biosensing systems are discussed in this review.

Abstract
DNA molecular machines are DNA self-assemblies that perform quasi-mechanical movement at the micro-nano scale, and have attracted increasing attention in the fields of biosensing, drug delivery and biocomputing. Herein, we report the concept and operation of an interparticle relatively motional DNA walker. The walker is composed of walking particles (WPs) and track particles (TPs). The WPs and TPs are obtained by respective functionalization of locked walking strands containing DNAzyme sequences and fluorophore-labelled track strands containing substrate sequences onto gold nanoparticles (AuNPs). Triggered by the target that specifically unlocks the walking strand, the liberated walking strands cooperatively hybridize with the track strands. The track strand gets cleaved by the DNAzyme, accompanied by the fluorophore release. The adjacent walking strand on the WP subsequently hybridizes to the next track strand, inducing the relative motion of the WP around the TP. After walking along the surface of one TP, the WP can continue to interact with another TP. As a result of the improved moving freedom and area, the interparticle motional mode induces high continuity and achieves large signal accumulation. Taking Zika virus RNA fragments (ZIKV-RNA) as a model target, the DNA walker shows a high sensitivity with a detection limit of 118 pM, and can reliably detect the target in biological fluids due to the stability of its components. The constructed DNA walker provides a new type of free and robust motion mode between particles and holds potential in clinical diagnosis.

Abstract
An electrochemical method is described for ultrasensitive determination of protein tyrosine kinase-7 (PTK7). It is based on (a) the use of positively charged gold nanoparticles (AuNPs) and negatively charged graphene oxide (GO), and (b) of toehold-mediated strand displacement amplification. A hairpin probe 2 (HP2) containing the sgc8 aptamer was used to modify a glassy carbon electrode (GCE). Its hairpin structure is opened in the presence of PTK7 to form the PTK7-HP2 complex. The exposed part of HP2 partly hybridizes with hairpin probe 1 (HP1) that was immobilizing on the AuNPs and GO modified GCE. On addition of the hairpin probe 3 that was labeled with the redox probe Methylene Blue (MB-HP3), toehold-mediated strand displacement occurs due to complementary hybridization of HP1 with MB-HP3. This causes the release of PTK7-HP2 into the solution and makes it available for the next reaction. Under optimal conditions, PTK7 can be quantified by voltammetry (typically performed at -0.18 V) with a detection limit of 1.8 fM. The assay possesses high selectivity for PTK7 due to the employment of the aptamer. It was successfully applied to the determination of PTK7 in the debris of malignant melanoma A375 cells. Graphical abstract Schematic representation of the enzyme-free electrochemical sensor for ultrasensitive determination of protein tyrosine kinase-7 (PTK7) based on the toehold-mediated strand displacement reaction amplification on gold nanoparticles and graphene oxide.

Abstract
A method is described for the determination of DNA via nucleic acid amplification by using nucleic acid concatemers that result from DNA supersandwich self-assemblies (SSAs). The method employs two auxiliary probes to form self-assembled biotin SSAs. These exhibit strong fluorescence if labeled with intercalator SYBR Green I. In the presence of the target (as exemplified for a 30-mer), streptavidin is released from the surface of the functionalized magnetic microparticles (FMMPs) by competitive hybridization on the surface. However, the SSA products do not conjugate to the FMMPs. This leads to a large amount of SYBR Green I intercalated into the concatemers and eventually results in amplified fluorescence in the supernate. The SSA products can be prepared beforehand, and amplification therefore can be completed within 50 min. The method is more efficient than any other conventional amplification. The detection limit for the 30-mer is 26.4 fM which is better by a factor of 10 compared to other amplification methods. Conceivably, the method can be further extended to the determination of a wide variety of targets simply by replacing the sequences of the probes. Finally, this rapid and highly sensitive method was employed for detection of Ebola virus gene (≈30-mer) and ATP in spiked serum with satisfactory results. Graphical abstract A high sensitivity and efficiency bioassay is described based on functionalized magnetic microparticles and DNA supersandwich self-assemblies.

Abstract
Nucleic acids are considered as perfect programmable materials for cascade signal amplification and not merely as genetic information carriers. Among them, catalytic hairpin assembly (CHA), an enzyme-free, high-efficiency, and isothermal amplification method, is a typical example. A typical CHA reaction is initiated by single-stranded analytes, and substrate hairpins are successively opened, resulting in thermodynamically stable duplexes. CHA circuits, which were first proposed in 2008, present dozens of systems today. Through in-depth research on mechanisms, the CHA circuits have been continuously enriched with diverse reaction systems and improved analytical performance. After a short time, the CHA reaction can realize exponential amplification under isothermal conditions. Under certain conditions, the CHA reaction can even achieve 600 000-fold signal amplification. Owing to its promising versatility, CHA is able to be applied for analysis of various markers in vitro and in living cells. Also, CHA is integrated with nanomaterials and other molecular biotechnologies to produce diverse readouts. Herein, the varied CHA mechanisms, hairpin designs, and reaction conditions are introduced in detail. Additionally, biosensors based on CHA are presented. Finally, challenges and the outlook of CHA development are considered.

Abstract
Three-dimensional (3D) DNA walking machines inspired by natural molecular machines have attracted significant attention due to their high walking efficiency and signal amplification capability. Herein, we report a 3D DNA walking machine for the dual-modal detection of miRNA using a fluorometer and personal glucose meter (PGM). The 3D DNA walking machine on magnetic beads (MBs) was coated with the BHQ-H1-FAM hairpin structures (DNA tracks), activated by target miRNA-21 (walking strand) and propelled by a strand displacement reaction. During these processes, the fluorescence of FAM on H1 was turned on (first signal), and the invertase on H2 was introduced into the surface of the MBs. After being separated by an external magnetic field, the invertase hydrolyzed sucrose into glucose to generate a second signal, which was quantified by the PGM. The developed 3D DNA walking machine showed high sensitivity and good specificity, and the detection limits of 98 pM and 60 pM were obtained for the fluorescence-based assay and PGM-based assay, respectively. Compared with the single-modal detection, the developed DNA walking machine can achieve a unique double signal readout and more reliable sensitive performance. In addition, the proposed 3D DNA walking machine was successfully applied to detect miRNA in real biological samples. The 3D DNA walking machine with dual-modal detection has potential applications in disease diagnostics and clinical applications and can satisfy different testing requirements both in the laboratory and field.

Abstract
Biosensors are analytical devices for biomolecule detection that compromise three essential components: recognition moiety, transducer, and signal processor. The sensor converts biomolecule recognition to detectable signals, which has been applied in diverse fields such as clinical monitoring, in vitro diagnostics, food industry etc. Based on signal transduction mechanisms, biosensors can be categorized into three major types: optical biosensors, electrochemical biosensors, and mass-based biosensors. Recently, the need for faster, more sensitive detection of biomolecules has compeled researchers to develop various sensing techniques. In this review, the basic structure and sensing principles of biosensors are introduced. Additionally, the review discusses multiple recent works about nucleic acid and exosome sensing.

Abstract
Here, we propose a new two-layer three-dimensional (3-D) DNA walker sensor with highly integrated entropy-driven and enzyme-powered reactions for the first time. The 3-D DNA walker sensor is constructed by assembling densely carboxyfluorescein-labeled single strand oligonucleotides (inner-layer tracks) and nucleic acid complex S (outer-layer tracks) on a microparticle. In the presence of the target, outer and inner tracks are activated in turn, thereby releasing a great deal of the signal reporters for signal reading. As a result, our 3-D DNA walker sensor can realize the target detection in the range from 2 pM to 5 nM within one hour. Besides, the specific walker sensor can clearly distinguish even one-base mismatched target analogue. More importantly, our walker sensor can also test the target in human serum samples in the concentrations as low as 0.1 nM, which provides a bridge between real sample detection and clinical application. Certainly, this smart strategy could also be generalized to any target of interest by proper design.

Abstract
HIV nucleic acids, one kind of significant biomarker, play an important role in fundamental studies and clinical diagnosis. Importantly, the early accurate diagnosis for HIV nucleic acids at ultralow concentrations can potentially extend the life of patients. In the current work, we developed a DNA nanomachine on gold nanoparticles (AuNPs) coupling rolling circle amplification and DNA walker cascade amplification for ultrasensitive detection of HIV nucleic acids. This DNA nanomachine sensing strategy exhibits a significantly low detection limit down to 1.46 fM. Furthermore, this DNA nanomachine biosensor is capable of detecting target DNA in real samples because of its high selectivity and sensitivity. Moreover, the DNA nanomachine biosensor is capable of discriminating single-base mismatch lower than 3.5 pM. The results showed that this DNA nanomachine biosensor has the potential for biomedical studies and clinical applications.

Abstract
A molecular beacon (MB) is an oligonucleotide hybridization probe with a hairpin-shaped structure that leads to specific and instantaneous nucleic acid hybridization, enabling a variety of applications. However, integration of additional module sequences interferes with the performance of MBs and increases the complexity of sequence design. Herein, we develop and characterize a toehold integrated molecular beacon (ToMB) strategy for nucleic acid hybridization, where the reaction rate can be flexibly regulated by a target-induced MB conformational switch. Using this basic mechanism, the ToMB is capable of identifying nucleic acids with high specificity and a wider linearity range compared with the conventional molecular beacon system. We further applied the ToMB to the construction of a hybridization chain reaction system and a basic OR logic gate VJHto explore its programmability and versatility. Our results strongly suggest that the novel ToMB can act as a powerful nano-module to construct universal and multifunctional biosensors or molecular computations. Graphical abstract Molecular beacon is employed as a flexible and switchable spacer to control the toehold-mediated strand displacement reaction.
