Abstract
We have developed a hook-equipped DNA nanomachine (HDNM) for the rapid detection of specific nucleic acid sequences without a preamplification step. HDNM efficiently unwinds RNA structures and improves the detection sensitivity. Compared to the hookless system, HDNM offers an 80-fold and 13-fold enhancement in DNA and RNA detection, respectively, reducing incubation time from 3 to 1 h.

Abstract
African swine fever (ASF) and postweaning multisystemic wasting syndrome (PMWS) are acute infectious diseases caused by the African swine fever virus (ASFV) and porcine circovirus type 2 (PCV2). At present, there are no effective vaccines for the prevention of ASFV. PMWS, which is harmful to the domestic and even the world pig industry, is difficult to cure and has a high mortality. So, developing simple, inexpensive, and accurate analytical methods to detect and effectively diagnose ASFV and PCV2 can be conducive to avoid ASFV and PCV2 infection. CRISPR has become a potentially rapid diagnostic tool due to recent discoveries of the trans-cleavage properties of CRISPR type V effectors. Herein, we report the visual detection based on CRISPR-Cas12a (cpf1), which is more convenient than fluorescence detection. Through in vitro cleavage target DNA activation, Cas12a can trans-cleavage ssDNA G-quadruplex. TMB/H2O2 and Hemin cannot be catalyzed by cleavaged G-DNA to produce green color products. This protocol is useful for the detection of ASFV and PCV2 with high sensitivity. This method can enable the development of visual and label-free ASFV and PCV2 detection and can be carried out in the field without relying on instruments or power. This method can complete nucleic acid detection at 37 °C without using other instruments or energy. Our research has expanded the application of Cas12a and laid the foundation for the field's rapid detection of viral nucleic acid in future.

Abstract
Nucleic acid-based detection of RNA viruses requires annealing procedure to obtain RNA/probe or RNA/primer complexes for unwinding stable structure of folded viral RNA. In this study, we designed a protein enzymes-free nano-construction, names four-armed DNA machine (4DNM), that requires neither amplification stage nor high temperature annealing step for SARS-CoV-2 detection. It uses binary deoxyribozyme (BiDz) sensor incorporated in a DNA nanostructure equipped with total of four RNA-binding arms. Additional arms improved limit of detection at least 10 times. The sensor distinguished SARS-CoV-2 from other respiratory viruses and correctly identified five positive and six negative clinical samples verified by quantitative polymerase chain reaction (RT-qPCR). The strategy reported here can be used for detection of long natural RNA and can become a basis for a point-of-care or home diagnostic test.

Abstract
DNA tiles form through self-assembly of a small number of DNA strands that interact through basic repeated interactions, allowing the growth of nanoscale structures seeded by molecular inputs. If an approach for catalytic signal amplification can be integrated into the resultant nanostructure, then one can anticipate biosensing or diagnostic applications mediated by DNA tile self-assembly. Here, two-dimensional DNA tiles with split quadruplexes were designed as diagnostic tools for nucleic acid sensing without the use of protein enzymes. The presence of a target sequence leads to formation of extended microscale structures with arrayed multiple G-quadruplexes across the tile plane, with catalytic activity coupled to a colorimetric reporter. Such a mechanism has potential for low-cost signal amplification using unmodified DNA without the use of protein enzymes for biosensing.

Abstract
Molecular circuits have been used in a wide range of diagnosis applications, from the detection of chemical molecules in solution to the complex processing of cell surface receptors. One of the most important challenges of these systems is the lack of distinguishability between different circuit states when each circuit state represents a specific disease. In this work, we designed a molecular amplification circuit with borderline Boolean states that each state can be distinguished with different color intensity. For this purpose, two DNA complexes and four DNA hairpin structures were designed to detect miR-218 and miR-215 biomarkers. One of the designed DNA complexes has two G-quadruplex structures and the other has only one G-quadruplex structure. In the absence of the inputs, all three G-quadruplex structures are active and produce a high-intensity signal, while in the other three states, including the presence of miR-218, the presence of miR-215, and the presence of both inputs, respectively, one, two, and zero G-quadruplex structures are active. Therefore, the designed system can identify two different biomarkers simultaneously with different signal ratios, which can easily distinguish the different states of the circuit. This strategy is very promising to identify diseases in which any combination of biomarkers leads to a particular disease.

Abstract
Visual detection of ssRNA and dsDNA amplicons was achieved at room temperature without the need for a probe-analyte annealing stage. This approach uses a DNA nanostructure equipped with two analyte-binding arms. Highly selective binding of the third arm leads to the formation of a G-quadruplex structure capable of changing the solution color.

Abstract
A DNA aptazyme consists of an aptamer domain and a DNAzyme module, in which the DNAzyme activity can be regulated by the aptamer-target interaction. The complex of G-quadruplex (GQ) and hemin is a peroxidase-mimicking DNAzyme and has become increasingly popular as a reporter system for biosensing applications. The development of GQ-based aptazymes is of high interest as they can be used as label-free biosensors for the real-time detection of pathogens. Herein, we rationally designed ca. 200 GQ-based aptazyme candidates and evaluated the suitability of 14 aptamers targeting quinine, Protein A, Staphylococcus enterotoxin B, and ATP for this detection concept. As a result, six novel aptazymes were developed for the specific detection of quinine based on two quinine-binding aptamers. The rest of designed probes, however, hardly showed significant functionality. To uncover the reasons, we performed enzyme-linked oligonucleotide assays to find how the affinity of aptamers is affected once conjugated to the DNAzyme sequence or upon integration into the aptazyme probe. Furthermore, we investigated the impact of the structure-switching functionality in the parent aptamer and the effect of the reaction matrix on the efficiency of probes.

Abstract
Engineered nanopipette tools have recently emerged as a powerful approach for electrochemical nanosensing, which has major implications in both fundamental biological research and biomedical applications. Herein, we describe a generic method of target-triggered assembly of aptamers in a nanopipette for nanosensing, which is exemplified by sensitive and rapid electrochemical single-cell analysis of adenosine triphosphate (ATP), a ubiquitous energy source in life and important signaling molecules in many physiological processes. Specifically, a layer of thiolated aptamers is immobilized onto a Au-coated interior wall of a nanopipette tip. With backfilled pairing aptamers, the engineered nanopipette is then used for probing intracellular ATP via the ATP-dependent linkage of the split aptamers. Due to the higher surface charge density from the aptamer assembly, the nanosensor would exhibit an enhanced rectification signal. Besides, this ATP-responsive nanopipette tool possesses excellent selectivity and stability as well as high recyclability. This work provides a practical single-cell nanosensor capable of intracellular ATP analysis. More generally, integrated with other split recognition elements, the proposed mechanism could serve as a viable basis for addressing many other important biological species.

Abstract
The contamination of heavy metals (e.g., Hg, Pb, Cd and As) poses great risks to the environment and human health. Rapid and simple detection of heavy metals of considerable toxicity in low concentration levels is an important task in biological and environmental analysis. Among the many convenient detection methods for heavy metals, DNA-inspired gold nanoparticles (DNA-AuNPs) have become a well-established approach, in which assembly/disassembly of AuNPs is used for colorimetric signaling of the recognition event between DNA and target heavy metals at the AuNP interface. This review focuses on the recent efforts of employing DNA to manipulate the interfacial properties of AuNPs, as well as the major advances in the colorimetric detection of heavy metals. Beginning with the introduction of the fundamental aspects of DNA and AuNPs, three main strategies of constructing DNA-AuNPs with DNA binding-responsive interface are discussed, namely, crosslinking, electrostatic interaction and base pair stacking. Then, recent achievements in colorimetric biosensing of heavy metals based on manipulation of the interface of DNA-AuNPs are surveyed and compared. Finally, perspectives on challenges and opportunities for future research in this field are provided.

Abstract
Peroxidase-like DNAzymes have been extensively used to replace horseradish peroxidase (HRP) for developing biosensors for signal amplification. However, the background activity from the cofactor (i.e., free hemin) has limited the sensitivity of such sensors. Herein, we aim to find an inhibitor for hemin to suppress the background signal, and a classic split DNAzyme-based sensor was used to detect a complementary DNA oligonucleotide. After screening a series of dyes, SYBR Green I (SG, one of the DNA stanning dyes) was selected for suppressing the background. Simply by adding 0.84 μM SG, the background from 50 nM hemin was suppressed over 30-fold. The suppression was caused by the interaction between SG and hemin. In the presence of the target DNA, the formed duplex region and G-quadruplex structure can better bind SG and hemin respectively, thus preventing the interaction between them and showing a high activity of the DNAzyme. The optimized sensor showed a detection limit of 3.8 pM for the target DNA (p53 gene). In addition, the backgrounds from chemiluminescence, colorimetric and fluorescence sensing modes can all be reduced by adding SG to the split DNAzyme system. The suppression of the background of peroxidase DNAzymes is a critical step towards practical use of related biosensors.

Abstract
It is generally acknowledged that G-quadruplexes (G4s) acquire peroxidase activity upon interaction with hemin. Hemin has been demonstrated to bind selectively to the 3′-terminal G-tetrad of parallel G4s via end-stacking; however, the relationships between different terminal G-tetrads and the catalytic functions of G4/hemin DNAzymes are not fully understood. Herein, the oligonucleotide d(AGGGGA) and its three analogues, d(AGBrGBrGGA), d(AGBrGGGBrA) and d(AGBrGGBrGA) (GBr indicates 8-bromo-2′-deoxyguanosine), were designed. These oligonucleotides form three parallel G4s and one antiparallel G4 without loop regions. The scaffolds had terminal G-tetrads that were either anti-deoxyguanosines (anti-dGs) or syn-deoxyguanosines (syn-dGs) at different proportions. The results showed that the parallel G4 DNAzymes exhibited 2 to 5-fold higher peroxidase activities than the antiparallel G4 DNAzyme, which is due to the absence of the 3′-terminal G-tetrad in the antiparallel G4. Furthermore, the 3′-terminal G-tetrad consisting of four anti-dGs in parallel G4s was more energetically favorable and thus more preferable for hemin stacking compared with that consisting of four syn-dGs. We further investigated the influence of 3′ and 5′ deoxyadenosine (dA) caps on the enzymatic performance by adding 3′-3′ or 5′-5′ phosphodiester bonds to AG4A. Our data demonstrated that 3′ dA caps are versatile residues in promoting the interaction of G4s with hemin. Thus, by increasing the number of 3′ dA caps, the DNAzyme of 3′A5′-5′GG3′-3′GG5′-5′A3′ with two 5′-terminal G-tetrads can exhibit significantly high catalytic activity, which is comparable to that of 5′A3′-3′GG5′-5′GG3′-3′A5′ with two 3′-terminal G-tetrads. This study may provide insights into the catalytic mechanism of G4-based DNAzymes and strategies for promoting their catalytic activities.

Abstract
Hybridization probes have become an indispensable tool for nucleic acid analysis. Systematic efforts in probe optimization resulted in their improved binding affinity, turn-on ratios, and ability to discriminate single nucleotide substitutions (SNSs). The use of split (or multicomponent) probes is a promising strategy to improve probe selectivity and enable an analysis of folded analytes. Here, we developed criteria for the rational design of a split G-quadruplex (G4) peroxidase-like deoxyribozyme (sPDz) probe that provides a visual output signal. The sPDz probe consists of two DNA strands that hybridize to the abutting positions of a DNA/RNA target and form a G4 structure catalyzing, in the presence of a hemin cofactor, H2O2-mediated oxidation of organic compounds into their colored oxidation products. We have demonstrated that probe design becomes complicated in the case of target sequences containing clusters (two or more) of cytosine residues and developed strategies to overcome the challenges to achieving high signal-to-noise and excellent SNS discrimination. Specifically, to improve selectivity, a conformational constraint that stabilizes the probe's dissociated state is beneficial. If the signal intensity is compromised, introduction of flexible non-nucleotide linkers between the G4-forming and target-recognizing elements of the probe helps to decrease the steric hindrance for G4 PDz formation observed as a signal increase. Varying the modes of G4 core splitting is another instrument for the optimal sPDz design. The suggested algorithm was successfully utilized for the design of the sPDz probe interrogating a fragment of the Influenza A virus genome (subtype H1N1), which can be of practical use for flu diagnostics and surveillance.

Abstract
Distinct from intermolecular split G-quadruplex (Inter-SG), intramolecular split G-quadruplex (Intra-SG) which could be generated in a DNA spacer-inserted G-quadruplex strand has not been systematically explored. Not only is it essential for the purpose of simplicity of DNA-based bioanalytical applications, but also it will give us hints how to design split G-quadruplex-based system. Herein, comprehensive information is provided about influences of spacer length and split mode on the formation of Intra-SG, how to adjust its thermodynamic stability, and selection of optimal Intra-SG for bioanalysis. For instances, non-classical Intra-SG (e.g. 2:10, 4:8 and 5:7) displays lower stability than classical split strands (3:9, 6:6 and 9:3), which is closely related to integrity of consecutive guanine tract; as compared to regular Intra-SG structures, single-thymine capped ones have reduced melting temperature, providing an effective approach to adjustment of stability. It is believed that the disclosed rules in this study will contribute to the effective application of split G-quadruplex in the field of DNA technology in the future.

Abstract
Nucleic acid-based techniques could achieve highly sensitive detection by amplifying template molecules to millions of folds. It has been one of the most valued analytical methods and is applied in many detection fields, such as diagnosis of infectious diseases, food safety assurance and so on. Nucleic acid-based techniques consist of three steps: nucleic acid extraction, amplification, and product detection. Among them, the detection step plays a vital role because it shows the results directly. As the trend of detection is simple, rapid and instrument-free, it is of necessity to carry out visual detection, where the result read-out could be visible and distinguished by the naked eye. In this critical review, advanced visual detection methods are summarized and discussed in detail, aiming to promote the potential application in on-site detection.

Abstract
Inspired by the increasing use of plasmonic gold and silver nanoplates as probes for diverse analytes, the research community often questions which metal nanoplates should be chosen for a given application. A comparative study was performed on the performance and physicochemical properties of three types of metal nanoplates for use in plasmonic detection of Hg(II) ion. Specifically, gold, silver and Ag@Au nanoplates were studied. The established amalgamation method integrated into a detection scheme using nanoplates affords a unique yet straightforward signaling and extraction route for selective recognition of Hg(II) ion. Upon transformation of Hg(II) ion to metallic mercury, nanoplate amalgamation takes place instantly. This reshapes both the morphology and the optical characteristics of nanoplates. It is found that gold and Ag@Au nanoplates enable highly selective quantitation of Hg(II) ion by using a DNA oligomer consisting of poly-deoxycytidine (poly(C)) as a masking agent against Ag(I) ion. The silver nanoplates, in turn, display the best sensitivity owing to the chemical instability. The induced surface plasmonic shifts (of up to 250 nm and color changes from red to green) allows for determination of Hg(II) over a wide range and with a limit of detection of ~10 nM. It is recommended that the gold and Ag@Au nanoplates are used in relatively complex systems, while silver nanoplates are suited for simple matrices. Graphic abstract The amalgamation process integrated with metal (e.g., Au, Ag and Ag@Au) nanoplates affords plasmonic detection of Hg(II) ion with the aid of a poly(c) DNA sequence as the masking agent for Ag(I) ion.

Abstract
Although DNA computing has exhibited a magical power across diverse areas, current DNA logic gates with different functions are always separately operated and can only produce hard-to-visualize output. The fussy/obligatory gates' redesign/reconstruction and the non-intuitive output cause the wastage of time and costs, low efficiency and practicality. Herein, inspired by the ancient Roman mythical God Janus, for the first time, we propose the concept of "DNA Janus Logic Pair" (DJLP) to classify the DNA logic gates with contrary functions into "Positive + Negative" gates (DJLP = Pos + Neg). Based on the biocatalytic property of G-quadruplex DNAzyme (G4zyme) and the luminescence quenching ability of oxidized 3,3',5,5'-tetramethylbenzidine (OxTMB) towards the upconversion (UC) particles, we fabricated a universal amphichromatic platform that kills two birds with one stone for operating a versatile DJLP library. Different from the previous DNA logic systems, the "Pos + Neg" gates of each DJLP in this study were concomitantly achieved via the same one-time DNA reaction, which avoided the gates' redesign/reoperation and reduced the operating costs/time of the DNA gates by at least half. Besides, both the amphichromatic outputs (Visual-blue and UC luminescent-green) can be visualized under harmless-NIR, thus bringing greatly enhanced practicality to the method. Moreover, we constructed various concatenated logic circuits via logically modulating the G4zyme's biocatalytic property with glutathione, thus enabling the largely improved computing complexity. Furthermore, taking the circuit "YES-INH-1-2 decoder" as the "computing core", we designed an "antioxidant indicator" with ratiometric logical responses that could recognize the presence of antioxidants smartly (output changed from "10" to "01"), which provided a typical prototype for potential intelligent bio-applications.

Abstract
Sensitive detection of nucleic acids and identification of single nucleotide polymorphism (SNP) is crucial in diagnosis of genetic diseases. Many strategies have been developed for detection and analysis of DNA, including fluorescence, electrical, optical, and mechanical methods. Recent advances in fluorescence resonance energy transfer (FRET)-based sensing have provided a new avenue for sensitive and quantitative detection of various types of biomolecules in simple, rapid, and recyclable platforms. Here, we report single-step FRET-based DNA sensors designed to work via a toehold-mediated strand displacement (TMSD) process, leading to a distinct change in the FRET efficiency upon target binding. Using single-molecule FRET (smFRET), we show that these sensors can be regenerated in situ, and they allow detection of femtomoles DNA without the need for target amplification while still using a dramatically small sample size (fewer than three orders of magnitude compared to the typical sample size of bulk fluorescence). In addition, these single-molecule sensors exhibit a dynamic range of approximately two orders of magnitude. Using one of the sensors, we demonstrate that the single-base mismatch sequence can be discriminated from a fully matched DNA target, showing a high specificity of the method. These sensors with simple and recyclable design, sensitive detection of DNA, and the ability to discriminate single-base mismatch sequences may find applications in quantitative analysis of nucleic acid biomarkers.

Novel strategy to improve the sensing performances of split ATP aptamer based fluorescent indicator displacement assay through enhanced molecular recognition. Biosens Bioelectron 2019; 134:36-41. [PMID: 30954924 DOI: 10.1016/j.bios.2019.03.047] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 03/19/2019] [Accepted: 03/22/2019] [Indexed: 12/24/2022]
Abstract
Split aptamer strategy was often used to improve the sensitivity of aptasensor. However, traditional split aptamer strategy can not be directly used to improve the label-free aptamer based Thioflavin T (ThT) displacement assay for ATP because the split ATP aptamer display much lower enhancement effects on the fluorescence of ThT than intact aptamer. In order to address this issue, this is the first report using G-rich DNA sequence to enhance the affinity of the two split ATP aptamer halves to ThT and offer lower limit of detection (LOD), wider linear range and higher selectivity through the enhanced molecular recognition. Compared to the intact aptamer/ThT complex, the ensemble of two G-rich split ATP aptamer fragments/ThT are higher fluorescent. Consequently, G-rich sequences would improve the fluorescent signal and thus the sensing performance of the proposed assay. In the optimized conditions, the LOD of the proposed fluorescent ATP aptasensor is 2 nM, which is lower than the reported ThT/ATP aptamer based methods. Additionally, our aptasensor has a wider dynamic linear range (0.1 μM - 120 μM) and higher selectivity. The proposed aptasensor has been successfully applied to detect ATP in 15% human serum. More importantly, the current study not only provides a novel method for ATP assay but also presents a way to construct a label-free split aptamer based fluorescent sensor for other species where aptamer can be generated.

Abstract
G-quadruplexes are made up of guanine-rich RNA and DNA sequences capable of forming noncanonical nucleic acid secondary structures. The base-specific sterical configuration of G-quadruplexes allows the stacked G-tetrads to bind certain planar molecules like hemin (iron (III)-protoporphyrin IX) to regulate enzymatic-like functions such as peroxidase-mimicking activity, hence the use of the term DNAzyme/RNAzyme. This ability has been widely touted as a suitable substitute to conventional enzymatic reporter systems in diagnostics. This review will provide a brief overview of the G-quadruplex architecture as well as the many forms of reporter systems ranging from absorbance to luminescence readouts in various platforms. Furthermore, some challenges and improvements that have been introduced to improve the application of G-quadruplex in diagnostics will be highlighted. As the field of diagnostics has evolved to apply different detection systems, the need for alternative reporter systems such as G-quadruplexes is also paramount.

Abstract
Due to structual polymorphism, excellent binding activity and functional significances in biological regulation, G-quadruplex has become the focus of research as an innovated module for analytical chemistry and biomedicine. Meanwhile, in the biosensor fields, new nanomaterial graphene oxide (GO) has also received extensive attention due to its brilliant physical and chemical properties. Herein, we propose a non-label and enzyme-free logic operation platform based on G-quadruplex structure and GO instead of any expensive modification. Taking advantage of the quenching ability of GO to AgNCs and the fluorescence enhancement of NMM (N-methylmesoporphyrin IX) mediated by the split G-quadruplex, a series of binary logic gates (AND, OR, INHIBIT, XOR) have been constructed and verified by biological experiments. Subsequently, two combinatorial logic gates were successfully realized conceptually on the basis of the same BGG platform, including half adder and half subtractor. Taken together, such a universal platform has great potential in applications, such as biocomputing, bio-imaging and disease diagnosis, which cultivate a new view for future biological research.

Abstract
Contamination of foods by aflatoxin B1 (AFB1) is a common serious problem. To improve the efficiency of AFB1 detection, this study aims to develop a sensitive aptasensor for detection of AFB1 in food samples based on the catalytic effect of aptamer/G-quadruplex DNAzyme probe. The resulting reassembly of this probe in the presence of hemin and K+ catalyzes the generation of fluorescent 2,3-diaminophenazine (DAP) from o-phenylenediamine (OPD). Interestingly, we first found that the high background induced by the superfluous hemin can be effectively suppressed with the aid of sequential adsorption and magnetic separation by magnetic oxidized multiwall carbon nanotubes (Fe3O4@oMWCNTs). This aptasensor exhibits a high sensitivity toward AFB1 with a detection limit of 0.02 ng/mL. The assay also shows higher selectivity for AFB1 compared to other reported agents and can be employed to detect AFB1 in foodstuffs, which might find broad practical applications in other food contaminants determination.

Abstract
Aptameric sensors can bind molecular targets and produce output signals, a phenomenon that is used in bioassays. In some cases, it is important to distinguish between monomeric and oligomeric forms of a target. Here, we propose a strategy to convert a monomer/oligomer-nonselective sensor into an oligomer-selective sensor. We designed an aptazyme that produced a high fluorescent output in the presence of oligomeric α-synuclein (a molecular marker of Parkinson's disease) but not its monomeric form. The strategy is potentially useful in the design of point-of-care tests for the diagnosis of neurodegenerative diseases.

Abstract
Nanomedicine is a discipline that applies nanoscience and nanotechnology principles to the prevention, diagnosis, and treatment of human diseases. Self-assembly of molecular components is becoming a common strategy in the design and syntheses of nanomaterials for biomedical applications. In both natural and synthetic self-assembled nanostructures, molecular cooperativity is emerging as an important hallmark. In many cases, interplay of many types of noncovalent interactions leads to dynamic nanosystems with emergent properties where the whole is bigger than the sum of the parts. In this review, we provide a comprehensive analysis of the cooperativity principles in multiple self-assembled nanostructures. We discuss the molecular origin and quantitative modeling of cooperative behaviors. In selected systems, we describe the examples on how to leverage molecular cooperativity to design nanomedicine with improved diagnostic precision and therapeutic efficacy in medicine.

Abstract
We report several DNA nanodevices monitored with fluorogenic looped-out 2-aminopurine. It is found that looped-out 2-AP, an analogue of adenine, in split parallel G-quadruplexes, triplexes and duplexes always shows much higher fluorescence intensity than that in single- or double-stranded DNAs, due to the weaker quenching effects derived from the reduced base stacking environments. Taking advantage of these traits, we introduce a new strategy to monitor the behaviours of DNA nanodevices via the fluorescence signal output by utilizing changes in the base stacking environment of 2-AP. As proof-of-principle experiments, two nanoplatforms for detecting disease genes, as well as a triplex nanoswitch, are constructed and monitored by fluorogenic looped-out 2-AP, illustrating that fluorogenic looped-out 2-AP holds great promise for reading the behaviours of diverse DNA nanodevices. Compared with conventional fluorescence labelling, looped-out 2-AP as a reporter shows good photostability and can be quenched by base-pairing, thereby providing an efficient quencher-free methodology for monitoring DNA nanodevices.

Abstract
G-quadruplex has been developed as an innovator for analytical chemistry and biomedicine due to its vibrant binding activity, structural polymorphism, and critical roles in biological regulation. Herein, a simple but versatile platform was obtained by integrating split G-quadruplex and fluorophore into a molecular beacon, where the photoinduced electron transfer could occur when the fluorophore approached the preformed G-quadruplex/hemin complexes. Such design subtly combined the G4 disruption-induced fluorescent turn-on strategy and the photoinduced electron transfer property into one platform for constructing the logic circuits. On the basis of such a universal platform, a series of binary logic gates (OR, INHIBIT, AND, and XOR), a combinatorial gate (INHIBIT-OR), and even a complex logic operation for discrimination of multiples of three from natural numbers less than ten have been successfully achieved only by employing such platform as work unit and single-strand DNAs as inputs. The set-reset function of this platform could be realized by alternatively introducing blocking and releasing strands. In addition, this platform could operate in a biological matrix stably and precisely. Therefore, such a universal platform lays the foundation for complicating the logic systems, realizing the biocomputing and also points out a new direction for target detection.

Molecular diagnostics of drug-resistant pathogens require the analysis of point mutations in bacterial or viral genomes, which is usually performed by trained professionals and/or by sophisticated computer algorithms. We have developed a DNA-based logic system that autonomously analyzes mutations found in the genome of Mycobacterium tuberculosis complex (MTC) bacteria and communicates the output to a human user as alphanumeric characters read by the naked eye. The five-gate system displays "O" ("no infection") for the absence of MTC infection and "P" or "F" for passing or failing a drug-susceptibility test, respectively.

Abstract
A cascade nucleic acid amplification strategy is presented for fluorometric aptamer based determination of the model protein carcinoembryonic antigen (CEA). Amplification is accomplished by combining catalytic hairpin assembly (CHA) and hybridization chain reaction (HCR). In this assay, a specially designed single-stranded DNA containing the aptamer sequence (AS) specific for CEA is hybridized with an inhibitor strand (IS) to form a double-stranded DNA (IS@AS). In the presence of CEA, it will recognize and bind to the AS strand which causes the release of IS. By introducing two DNA hairpins (H1 and H2; these containing complementary sequences) CHA will be activated via the hybridization reactions of H1 and H2. This is accompanying by the formation of a double-stranded DNA (H1-H2) and the release of CEA@AS. The liberated CEA@AS further drives successive recycling of the CHA, thereby generating further copies of H1-H2. The resultant H1-H2 hybrids act as primers and trigger HCR with the help of other two DNA hairpins (H3 and H4) containing G-rich toehold at the 5'-terminus and 3'-terminus of H3 and H4, respectively. The fluorescent probe N-methyl mesoporphyrin IX (NMM) is finally intercalated into the G-rich domains of the long DNA nanostructures due to formation of G-quadruplex structures. This generates a fluorescent signal (best measured at excitation/emission wavelengths of 399/610 nm) that increases with the concentration of target (CEA). This aptamer-based fluorescence assay is highly sensitive and has a linear range that covers the 1 pg·mL-1 to 2 ng·mL-1 CEA concentration range, with a 0.3 pg·mL-1 detection limit. Graphical abstract By integrating catalytic hairpin assembly (CHA) and hybridization chain reaction (HCR) for effective signal enhancement, a novel cascade amplification strategy is presented to develop a sensitive and selective fluorescent method for the assay of the model protein carcinoembryonic antigen (CEA).

Abstract
So far all visual and instrument-free methods have been based on a color change. However, colorimetric assays cannot be used by blind or color-blind people. Here we introduce a liquid-to-gel transition as a general output platform. The signal output (a piece of gel) can be unambiguously distinguished from liquid both visually and by touch. This approach promises to contribute to the development of an accessible environment for visually impaired persons.

Abstract
Genetic mutations are important biomarkers for cancer diagnostics and surveillance. Preferably, the methods for mutation detection should be straightforward, highly specific and sensitive to low-level mutations within various sequence contexts, fast and applicable at room-temperature. Though some of the currently available methods have shown very encouraging results, their discrimination efficiency is still very low. Herein, we demonstrate a branch-migration based fluorescent probe (BM probe) which is able to identify the presence of known or unknown single-base variations at abundances down to 0.3%-1% within 5 min, even in highly GC-rich sequence regions. The discrimination factors between the perfect-match target and single-base mismatched target are determined to be 89-311 by measurement of their respective branch-migration products via polymerase elongation reactions. The BM probe not only enabled sensitive detection of two types of EGFR-associated point mutations located in GC-rich regions, but also successfully identified the BRAF V600E mutation in the serum from a thyroid cancer patient which could not be detected by the conventional sequencing method. The new method would be an ideal choice for high-throughput in vitro diagnostics and precise clinical treatment.

Abstract
Hybridization probes have been intensively used for nucleic acid analysis in medicine, forensics and fundamental research. Instantaneous hybridization probes (IHPs) enable signalling immediately after binding to a targeted DNA or RNA sequences without the need to isolate the probe-target complex (e. g. by gel electrophoresis). The two most common strategies for IHP design are conformational switches and split approach. A conformational switch changes its conformation and produces signal upon hybridization to a target. Split approach uses two (or more) strands that independently or semi independently bind the target and produce an output signal only if all components associate. Here, we compared the performance of split vs switch designs for deoxyribozyme (Dz) hybridization probes under optimal conditions for each of them. The split design was represented by binary Dz (BiDz) probes; while catalytic molecular beacon (CMB) probes represented the switch design. It was found that BiDz were significantly more selective than CMBs in recognition of single base substitution. CMBs produced high background signal when operated at 55°C. An important advantage of BiDz over CMB is more straightforward design and simplicity of assay optimization.

Abstract
The split G-quadruplex DNAzyme has emerged as a valuable tool for visual DNA detection. Here, we successfully integrated colorimetric split G-quadruplex DNAzyme assay with nucleic acid sequence-based amplification to generate a novel detection approach, allowing visual and rapid detection for the RNA of Shimen and HCLV strains of Classic Swine Fever Virus (CSFV). CSFV is a RNA virus that causes a highly contagious disease in domestic pigs and wild boar. With this method, we were able to detect as little as 10 copies/ml of CSF viral RNA within 3 h in serum samples taken from the field. No interference was encountered in the amplification and detection of Classic Swine Fever Virus in the presence of non-target RNA or DNA. Moreover, Shimen and HCLV strains of Classic Swine Fever Virus could be easily differentiated using the NASBA-DNAzyme system. These findings indicate the NASBA-DNAzyme system is a rapid and practical technique for detecting and discriminating CSFV strains and may be applied to the detection of other RNA viruses.

Abstract
White-light scanning interferometry (WLSI) is often used to study the surface profiles and properties of thin films because the strength of the technique lies in its ability to provide fast and high resolution measurements. An innovative attempt is made in this paper to apply WLSI as a time-domain spectroscopic system for localized surface plasmon resonance (LSPR) sensing. A WLSI-based spectrometer is constructed with a breadboard of WLSI in combination with a spectral centroid algorithm for noise reduction and performance improvement. Experimentally, the WLSI-based spectrometer exhibits a limit of detection (LOD) of 1.2 × 10-3 refractive index units (RIU), which is better than that obtained with a conventional UV-Vis spectrometer, by resolving the LSPR peak shift. Finally, the bio-applicability of the proposed spectrometer was investigated using the rs242557 tau gene, an Alzheimer's and Parkinson's disease biomarker. The LOD was calculated as 15 pM. These results demonstrate that the proposed WLSI-based spectrometer could become a sensitive time-domain spectroscopic biosensing platform.

Abstract
During any type of binary data transmission, the occurrence of bit errors is an inevitable and frequent problem suffered. These errors, which have fatal effects on the correct logic computation, especially in sophisticated logic circuits, can be checked through insertion of a parity generator (pG) at the transmitting end and a parity checker (pC) at the receiving end. Herein, taking even pG/pC as a model device, we constructed the first DNA-based molecular parity generator/checker (pG/pC) for error detection through data transmission, on a universal single-strand platform according to solely DNA hybridization. Compared with previous pG/pC systems, the distinct advantage of this one is that it can present not only fluorescence signals but also visual outputs, which can be directly recognized by the naked eye, using DNA inputs modulated split-G-quadruplex and its DNAzyme as signal reporters, thus greatly extending its potential practical applications. More importantly, an "Output-Correction" function was introduced into the pC for the first time, in which all of the erroneous outputs can be adequately corrected to their normal states, guaranteeing the regular operation of subsequent logic devices. Furthermore, through negative logic conversion towards the constructed even pG/pC, the odd pG/pC with equal functions was obtained. Furthermore, this system can also execute multi-input triggered concatenated logic computations with dual output-modes, which largely fulfilled the requirements of complicated computing.

Abstract
A new strategy of simple, inexpensive, rapid, and label-free single-nucleotide-polymorphism (SNP) detection using robust chemosensors with piezomicrogravimetric, surface plasmon resonance, or capacitive impedimetry (CI) signal transduction is reported. Using these chemosensors, selective detection of a genetically relevant oligonucleotide under FIA conditions within 2 min is accomplished. An invulnerable-to-nonspecific interaction molecularly imprinted polymer (MIP) with electrochemically synthesized probes of hexameric 2,2'-bithien-5-yl DNA analogues discriminating single purine-nucleobase mismatch at room temperature was used. With density functional theory modeling, the synthetic procedures developed, and isothermal titration calorimetry quantification, adenine (A)- or thymine (T)-substituted 2,2'-bithien-5-yl functional monomers capable of Watson-Crick nucleobase pairing with the TATAAA oligodeoxyribonucleotide template or its peptide nucleic acid (PNA) analogue were designed. Characterized by spectroscopic techniques, molecular cavities exposed the ordered nucleobases on the 2,2'-bithien-5-yl polymeric backbone of the TTTATA hexamer probe designed to hybridize the complementary TATAAA template. In that way, an artificial TATAAA-promoter sequence was formed in the MIP. The purine nucleobases of this sequence are known to be recognized by RNA polymerase to initiate the transcription in eukaryotes. The hexamer strongly hybridized TATAAA with the complex stability constant KsTTTATA-TATAAA = ka/kd ≈ 106 M-1, as high as that characteristic for longer-chain DNA-PNA hybrids. The CI chemosensor revealed a 5 nM limit of detection, quite appreciable as for the hexadeoxyribonucleotide. Molecular imprinting increased the chemosensor sensitivity to the TATAAA analyte by over 4 times compared to that of the nonimprinted polymer. The herein-devised detection platform enabled the generation of a library of hexamer probes for typing the majority of SNP probes as well as studying a molecular mechanism of the complex transcription machinery, physics of single polymer molecules, and stable genetic nanomaterials.

Abstract
The Nobel prize in chemistry in 2016 was awarded for 'the design and synthesis of molecular machines'. Here we designed and assembled a molecular machine for the detection of specific RNA molecules. An association of several DNA strands, named multifunctional DNA machine for RNA analysis (MDMR1), was designed to (i) unwind RNA with the help of RNA-binding arms, (ii) selectively recognize a targeted RNA fragment, (iii) attract a signal-producing substrate and (iv) amplify the fluorescent signal by catalysis. MDMR1 enabled detection of 16S rRNA at concentrations ∼24 times lower than that by a traditional deoxyribozyme probe.

Abstract
Biosensors are analytical devices that have found a variety of applications in medical diagnostics, food quality control, environmental monitoring and biodefense. In recent years, functional nucleic acids, such as aptamers and nucleic acid enzymes, have shown great potential in biosensor development due to their excellent ability in target recognition and catalysis. Deoxyribozymes (or DNAzymes) are single-stranded DNA molecules with catalytic activity and can be isolated to recognize a wide range of analytes through the process of in vitro selection. By using various signal transduction mechanisms, DNAzymes can be engineered into fluorescent, colorimetric, electrochemical and chemiluminescent biosensors. Among them, colorimetric sensors represent an attractive option as the signal can be easily detected by the naked eye. This reduces reliance on complex and expensive equipment. In this review, we will discuss the recent progress in the development of colorimetric biosensors that make use of DNAzymes and the prospect of employing these sensors in a range of chemical and biological applications.
