Abstract
MicroRNAs (miRNAs) are a class of small noncoding RNAs that are approximately 22 nt in length and regulate gene expression post-transcriptionally. miRNAs play a vital role in both physiological and pathological processes and are regarded as promising biomarkers for cancer, cardiovascular diseases, neurodegenerative diseases, and so on. Accurate detection of miRNA expression level in clinical samples is important for miRNA-guided diagnostics. However, the common miRNA detection approaches like RNA sequencing, qRT-PCR, and miRNA microarray are performed in a professional laboratory with complex intermediate steps and are time-consuming and costly, challenging the miRNA-guided diagnostics. Hence, sensitive, highly specific, rapid, and easy-to-use detection of miRNAs is crucial for clinical diagnosis based on miRNAs. With the advantages of being specific, sensitive, efficient, cost-saving, and easy to operate, point-of-care testing (POCT) has been widely used in the detection of miRNAs. For the first time, we mainly focus on summarizing the research progress in POCT of miRNAs based on portable instruments and visual readout methods. As widely available pocket-size portable instruments and visual detection play important roles in POCT, we provide an all-sided discussion of the principles of these methods and their main limitations and challenges, in order to provide a guide for the development of more accurate, specific, and sensitive POCT methods for miRNA detection.

Abstract
RNAs are involved in the crucial processes of disease progression and have emerged as powerful therapeutic targets and diagnostic biomarkers. However, efficient delivery of therapeutic RNA to the targeted location and precise detection of RNA markers remains challenging. Recently, more and more attention has been paid to applying nucleic acid nanoassemblies in diagnosing and treating. Due to the flexibility and deformability of nucleic acids, the nanoassemblies could be fabricated with different shapes and structures. With hybridization, nucleic acid nanoassemblies, including DNA and RNA nanostructures, can be applied to enhance RNA therapeutics and diagnosis. This review briefly introduces the construction and properties of different nucleic acid nanoassemblies and their applications for RNA therapy and diagnosis and makes further prospects for their development.

Abstract
Catalytic hairpin assembly (CHA) appears to be a particularly appealing nucleic acid circuit because of its powerful amplification capability, simple protocols, and enzyme-free and isothermal conditions, and can combine with various signal output modes for the biosensing of various analytes. Especially in the last five years, vast CHA related studies have sprung up. With the deep exploration of the CHA mechanism, some novel and excellent CHA strategies have been proposed; meanwhile the CHA cascade strategies with various amplification techniques further improve the analysis performance. Furthermore, diverse CHA based biosensors have been tactfully engineered and extensively employed in imaging applications in living cells and in vivo ascribed to its gentle reaction, efficient amplification and universality. Hence, we present a comprehensive and systematic summary of the progress in CHA and its application in bioimaging and biomedicine to date. At first, we introduced the mechanism and diversification of CHA in detail, including the newly developed CHA and its ingenious combination with a variety of other technologies. Concurrently, we summarized the latest application progress of different CHA strategies in bioimaging and biomedicine, highlighting the merits and drawbacks of representative approaches. Finally, we put forward some views on the challenges and prospects of CHA in bioimaging and biomedicine in the future.

Abstract
DNA can adopt noncanonical structures that have important biological functions while also providing structural diversity for applications in nanotechnology. Here, the crystal structures of two oligonucleotides composed of d(CGA) triplet repeats in the parallel-stranded duplex form are described. The structure determination of four unique d(CGA)-based parallel-stranded duplexes across two crystal structures has allowed the structural parameters of d(CGA) triplets in the parallel-stranded duplex form to be characterized and established. These results show that d(CGA) units are highly uniform, but that each strand in the duplex is structurally unique and has a distinct role in accommodating structural asymmetries induced by the C-CH+ base pair.

Endogenous microRNA triggered enzyme-free DNA logic self-assembly for amplified bioimaging and enhanced gene therapy via in situ generation of siRNAs. J Nanobiotechnology 2021; 19:288. [PMID: 34565382 PMCID: PMC8474761 DOI: 10.1186/s12951-021-01040-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Accepted: 09/13/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Small interfering RNA (siRNA) has emerged as a kind of promising therapeutic agents for cancer therapy. However, the off-target effect and degradation are the main challenges for siRNAs delivery. Herein, an enzyme-free DNA amplification strategy initiated by a specific endogenous microRNA has been developed for in situ generation of siRNAs with enhanced gene therapy effect on cervical carcinoma. METHODS This strategy contains three DNA hairpins (H1, H2/PS and H3) which can be triggered by microRNA-21 (miR-21) for self-assembly of DNA nanowheels (DNWs). Notably, this system is consistent with the operation of a DNA logic circuitry containing cascaded "AND" gates with feedback mechanism. Accordingly, a versatile biosensing and bioimaging platform is fabricated for sensitive and specific analysis of miR-21 in HeLa cells via fluorescence resonance energy transfer (FRET). Meanwhile, since the vascular endothelial growth factor (VEGF) antisense and sense sequences are encoded in hairpin reactants, the performance of this DNA circuit leads to in situ assembly of VEGF siRNAs in DNWs, which can be specifically recognized and cleaved by Dicer for gene therapy of cervical carcinoma. RESULTS The proposed isothermal amplification approach exhibits high sensitivity for miR-21 with a detection limit of 0.25 pM and indicates excellent specificity to discriminate target miR-21 from the single-base mismatched sequence. Furthermore, this strategy achieves accurate and sensitive imaging analysis of the expression and distribution of miR-21 in different living cells. To note, compared to naked siRNAs alone, in situ siRNA generation shows a significantly enhanced gene silencing and anti-tumor effect due to the high reaction efficiency of DNA circuit and improved delivery stability of siRNAs. CONCLUSIONS The endogenous miRNA-activated DNA circuit provides an exciting opportunity to construct a general nanoplatform for precise cancer diagnosis and efficient gene therapy, which has an important significance in clinical translation.

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

Abstract
Herein, a metal-organic framework (UiO-66-NH2) with two functions (intrinsic fluorescence and fluorescence quenching ability) is designed to establish a ratiometric fluorescent platform for high-performance miRNA detection. The use of a fluorescent organic ligand endows the MOF material with a strong intrinsic fluorescence at 440 nm. In the presence of target miRNA, the fluorescence signal of the FAM is restored with the triple helix molecular beacons bind to the target. Using the IFAM/IMOF signal as the output, the prepared ratiometric probe was able to eliminate disturbance caused by the sensing environment. Under the optimal reaction conditions, including buffer pH of 7.4, temperature of 37 °C, and response time of 1 h, the best detection results can be obtained. The ratiometric fluorescence probe presented showed good sensitivity and selectivity for detecting miRNA-203 and the limit of detection was 400 pM with a wide linear range from 1 nM to 160 nM. In addition, this method was applied to diluted human serum and cell lysates, and good detection effect was realized.

Abstract
Real-time in situ monitoring of low-abundance cancer biomarkers (e.g., miRNAs and proteins) in living cells by nonenzymatic assembly entirely from original DNA probes remains unexplored due to an extremely complex intracellular environment. Herein, a nonenzymatic palindrome-catalyzed DNA assembly (NEPA) technique is developed to execute the in situ imaging of intracellular miRNAs by assembling a three-dimensional nanoscale DNA spherical structure (NS) with low mobility from three free hairpin-type DNAs rather than from DNA intermediates based on the interaction of designed terminal palindromes. Target miRNA was detected down to 1.4 pM, and its family members were distinguished with almost 100% accuracy. The subcellular localization of NS products can be visualized in real time. The NEPA-based sensing strategy is also suitable for the intracellular in situ fluorescence imaging of cancer-related protein receptors, offering valuable insight into developing sensing protocols for understanding the biological function of vital biomolecules in disease pathogenesis and future therapeutic applications.

Abstract
According to aptamer-mediated hairpin DNA cascade amplifier and gold nanoparticles aggregation, an optical platform for cancer cells determination has been proposed. High-affinity chimeric aptamers were used for cancer cell detection and also as an initiator for beginning hairpin assembly to construct three-way junction (3WJ) nanostructures. These three hairpins were modified at 3' ends with biotin. In the presence of target cell, chimeric aptamer binds to its ligand on cell surface and initiates 3WJ nanostructures formation. These 3WJ nanostructures interact with streptavidin-modified gold nanoparticles (AuNPs) via non-covalent biotin-streptavidin interactions and create a crossover lattice of nanoparticles. This event leads to AuNPs aggregation and red-shifting. The results were confirmed by gel electrophoresis and UV-visible spectrophotometry. The dynamic range of this assay is 25 to 107 cells with a detection limit of 10 cells which is respectively 9 and 4 times more significant than the sensitivity of AuNP-based approaches without amplification and enzyme-mediated signal amplification.

Abstract
MicroRNAs are involved in the crucial processes of development and diseases and have emerged as a new class of biomarkers. The field of DNA nanotechnology has shown great promise in the creation of novel microRNA biosensors that have utility in lab-based biosensing and potential for disease diagnostics. In this Survey and Summary, we explore and review DNA nanotechnology approaches for microRNA detection, surveying the literature for microRNA detection in three main areas of DNA nanostructures: DNA tetrahedra, DNA origami, and DNA devices and motifs. We take a critical look at the reviewed approaches, advantages and disadvantages of these methods in general, and a critical comparison of specific approaches. We conclude with a brief outlook on the future of DNA nanotechnology in biosensing for microRNA and beyond.

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
The monitoring and detection of molecular biomarkers play crucial roles in disease diagnosis and treatment. In this work, we proposed a target-responsive netlike hybridization chain reaction (nHCR) DNA nanostructure construction method, which can offer an exceptional signal enhancement, for highly sensitive fluorescence detection of cytokine, interferon-gamma (IFN-γ). The presence of the target cytokine can lead to the conformational change of the aptamer recognition hairpin probes and the liberation of the nHCR initiator strands, which further trigger the nHCR process between two dye-labeled and double hairpin-structured probes to form netlike DNA nanostructures. The formation of the DNA nanostructures brings the dyes into close proximity, resulting in significantly amplified fluorescence resonance energy transfer signals for sensitive and enzyme-free detection of IFN-γ. The present method has a detection limit of 1.2 pM and a dynamic linear range of 5 to 1000 pM for IFN-γ detection. Besides, with the high specificity of the aptamer probe and the significant signal amplification of the nHCR, such an IFN-γ detection strategy shows excellent selectivity and high sensitivity, which can be potentially applied to detect IFN-γ in human serums. With such a demonstration of the detection of IFN-γ, this proposed method can be extended for detecting different types of biomolecules.

Abstract
DNA has played an early and powerful role in the development of bottom-up nanotechnologies, not least because of DNA's precise, predictable, and controllable properties of assembly on the nanometer scale. Watson-Crick complementarity has been used to build complex 2D and 3D architectures and design a number of nanometer-scale systems for molecular computing, transport, motors, and biosensing applications. Most of such devices are built with classical B-DNA helices and involve classical A-T/U and G-C base pairs. However, in addition to the above components underlying the iconic double helix, a number of alternative pairing schemes of nucleobases are known. This review focuses on two of these noncanonical classes of DNA helices: G-quadruplexes and the i-motif. The unique properties of these two classes of DNA helix have been utilized toward some remarkable constructions and applications: G-wires; nanostructures such as DNA origami; reconfigurable structures and nanodevices; the formation and utilization of hemin-utilizing DNAzymes, capable of generating varied outputs from biosensing nanostructures; composite nanostructures made up of DNA as well as inorganic materials; and the construction of nanocarriers that show promise for the therapeutics of diseases.

Abstract
We fabricated a quencher-free and enzyme-free fluorescence detection system by employing the DNA logic circuits as signal amplifier and 2-aminopurine as signal indicator, and applied it to detect DNA and adenosine triphosphate (ATP). The assay system consisted of three hairpin probes with a sequestered 2-aminopurine molecule in each stem domain which was defined as inputs A, B and C of the logic operation. These three hairpin inputs kept stability and coexisted in reaction solution without target. However, adding target to the system would break the stability and initiate a dynamic assembly of the three inputs through toehold mediated displacement, resulting in the formation of three way junction and the liberation of 2-aminopurine from duplex structure. The structural circumstance changes from duplex to single stand switched the signal from "off" to "on" due to the disarming of base stack interaction, thus attaining amplified fluorescence detection without any extra quencher and avoiding the limitation of distance-independent signal conversion in conventional methods. A limit of detection of 0.46 pM was achieved for target DNA with high discrimination capability. Moreover, the sensing system was expandable for ATP detection. Importantly, the method was simple and easy-to-operate. These features make the DNA logic circuits adaptable as an enzyme-free and quencher-free amplifier, and thus the proposed method offers a powerful platform for DNA and ATP determination, and even other biotargets in clinical diagnosis.

Abstract
A novel turn-off colorimetric sensor for sequence-specific recognition of single-stranded DNA (ssDNA) was established by combining Y-shaped DNA duplex and G-quadruplex-hemin DNAzyme. A G-rich single-stranded DNA (Oligo-1) displays peroxidase mimicking catalytic activity due to the specific binding with hemin in the presence of K+, which was able to catalyze the oxidation of colorless 2,2'-azinobis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS2-) by H2O2 to generate green ABTS•- radical for colorimetric assay. Oligonucleotide 2 (Oligo-2) was partly complementary with Oligo-1 and the target DNA. Upon addition of target DNA, Oligo-1, Oligo-2 and target DNA can hybridize with each other to form Y-shaped DNA duplex. The DNAzyme sequence of Oligo-1 was partly caged into Y-shaped DNA duplex, resulting in the inactivation of the DNAzyme and a sharp decrease of the absorbance of the oxidation product of ABTS2-. Under the optimum condition, the absorbance decreased linearly with the concentration of target DNA over the range of 1.0-250 nM and the detection limit was 0.95 nM (3σ/slope) Moreover, satisfied result was obtained for the discrimination of single-base or two-base mismatched DNA.

Abstract
The illegal adulteration of melamine in dairy products for false protein content increase is a strong hazard to human health. Herein, a simple and sensitive colorimetric method was developed for the quantification of melamine in dairy products based on a Cu2+-hydrogen peroxide (H2O2)-3,3′,5,5′-tetramethylbenzidine (TMB) system. In this strategy, Cu2+ exhibits peroxidase-like activity and can catalyze the oxidation of TMB to oxidized TMB (oxTMB) in the presence of H2O2 with a blue colour change of the solution. However, the presence of melamine quickly interacts with H2O2 leading to the consumption of H2O2 and thus strongly hinders the oxidation of TMB. Under the optimal conditions, the absorbance change of oxTMB has a linear response to the concentration of melamine from 1 to 100 μM with a detection limit of 0.5 μM for melamine. The proposed method has many merits including more simplicity, good selectivity, and more cost-effectiveness without using any nanomaterials. The method was further successfully applied to detect melamine in dairy products including milk and infant formula powder. Convenient and sensitive colorimetric detection of melamine in dairy products based on a Cu(ii)-H2O2-3,3′,5,5′-tetramethylbenzidine system was reported.![]()

Abstract
In recent years, the analytical application of logical nanodevices has attracted much attention for making accurate decisions on molecular diagnosis. Herein, a DNA domino-based nanoscale logic circuit has been constructed by integrating three logic gates (AND-AND-YES) for simultaneous analysis of multiple nucleic acid biomarkers. In the first AND gate, a chimeric target DNA comprising of four biomarkers was hybridized to three biomarker-specific oligonucleotides (TRs) via their 5'-end regions and to a capture probe-magnetic microparticle. After harvesting the complex, 3' overhang regions of the TRs were labeled with three distinct monolayer double-stranded (ds) DNA-gold nanoparticles (DNA-AuNPs). Upon gleaning the complex and addition of initiator oligonucleotide, a series of toehold-mediated strand displacement reactions, which are reminiscent of a domino chain, spontaneously occurred between the confined dsDNAs on the nanoparticles' surface in the second AND gate. The output of the second gate entered into the last gate and triggered an exponential hairpin assembly to form four-way junction nanostructures. The resulting nanostructures bear split parts of DNAzyme at each end of the four arms which, in the presence of hemin, form catalytic hemin/G-quadruplex DNAzymes with peroxidase activity. The smart biosensor has exhibited a turn-on signal when all biomarkers are present in the sample. In fact, should any of the biomarkers be nonexistent, the signal remains turned-off. The biosensor can detect the biomarkers with a LOD value of 100 aM and a noticeable capability to discriminate single-nucleotide substitutions.

Abstract
A novel G-quadruplex DNAzyme-driven chemiluminescence (CL) imaging method has been developed for ultrasensitive and specific detection of BCR/ABL fusion gene based on bis-three-way junction (bis-3WJ) nanostructure and cascade DNA machineries. Bis-3WJ probes are designed logically to recognize BCR/ABL fusion gene, which forms the stable bis-3WJ nanostructure for the activation of polymerase/nicking enzyme machineries in cascade, resulting in synthesis of DNAzyme subunits. These DNAzyme subunits can form integrated DNAzyme by self-assembly to catalyze CL substrate, thus providing an amplified signal for the sensing events or outputs for AND logic operation. The imaging method achieved ultrasensitive detection of BCR/ABL fusion gene with a low detection limit down to 23 fM. And this method exhibited wide linear ranges over seven orders of magnitude and excellent discrimination ability toward target. In addition, an acceptable recovery was obtained in complex matrix. It is notable that this biosensing strategy possesses merits of homogenous, isothermal and label-free assay system. Therefore, these merits endow the developed imaging method with a potential tool for CML diagnosis.

Abstract
The use of DNA as a material for nanoscale construction has blossomed in the past decade. This is largely attributable to the DNA origami technique, which has enabled construction of nanostructures ranging from simple two-dimensional sheets to complex three-dimensional objects with defined curves and edges. These structures are amenable to site-specific functionalization with nanometer precision, and have been shown to exhibit cellular biocompatibility and permeability. The DNA origami technique has already found widespread use in a variety of emerging biological applications such as biosensing, enzyme cascades, biomolecular analysis, biomimetics, and drug delivery. We highlight a few of these applications and comments on the prospects for this rapidly expanding field of research.
