Abstract
Exosomes are membrane-enclosed phospholipid extracellular vesicles. In spite of their great promise as noninvasive biomarkers for cancer diagnosis, sensitive detection of exosomes is still challenging. Herein, the detection of exosomes was changed to the detection of DNA after recognition of exosomes with its aptamers. CD63 aptamer and EpCAM aptamer were used for the detection of MCF-7 cell-secreted exosome. The recognition process was amplified through the movements of a three-dimensional DNA walker. And then, Exonuclease III- assisted electrochemical ratiometric sensor was applied for further signal amplification. Under optimal conditions, the detection limit of 1.3 × 104 particles/mL was obtained with excellent selectivity. Furthermore, clinical application test for the detection of exosomes in human serum was also verified.

Abstract
Herein, by directly introducing mismatched reactant DNA, high-reactivity and high-threshold enzyme-free target recycling amplification (EFTRA) is explored. The developed high-efficiency EFTRA (HEEFTRA) was applied as a programmable DNA signal converter, possessing higher conversion efficiency than the traditional one with perfect complement owing to the more negative reaction standard free energy (ΔG). Once traces of input target miRNA interact with the mismatched reactant DNA, amounts of ferrocene (Fc)-labeled output DNA could be converted via the EFTRA. Impressively, the Fc-labeled output DNA could be easily captured by the DNA tetrahedron nanoprobes (DTNPs) on the electrode surface to form triplex-forming oligonucleotide (TFO) at pH = 7.0 for sensitive electrochemical signal generation and the DTNPs could be regenerated at pH = 10.0, from which the conversion efficiency (N) will be accurately obtained, benefiting the selection of suitable mismatched bases to obtain high-efficiency EFTRA (HEEFTRA). As a proof of concept, the HEEFTRA as an evolved DNA signal converter is successfully applied for the ultrasensitive detection of miRNA-21, which gives impetus to the design of other signal converters with excellent efficiency for ultimate applications in sensing analysis, clinical diagnosis, and other areas.

Abstract
DNA nanotechnology engineered at the solid-liquid interface has advanced our fundamental understanding of DNA hybridization kinetics and facilitated the design of improved biosensing, bioimaging and therapeutic platforms. Three research branches of DNA nanotechnology exist: (i) structural DNA nanotechnology for the construction of various nanoscale patterns; (ii) dynamic DNA nanotechnology for the operation of nanodevices; and (iii) functional DNA nanotechnology for the exploration of new DNA functions. Although the initial stages of DNA nanotechnology research began in aqueous solution, current research efforts have shifted to solid-liquid interfaces. Based on shape and component features, these interfaces can be classified as flat interfaces, nanoparticle interfaces, and soft interfaces of DNA origami and cell membranes. This review briefly discusses the development of DNA nanotechnology. We then highlight the important roles of structural DNA nanotechnology in tailoring the properties of flat interfaces and modifications of nanoparticle interfaces, and extensively review their successful bioapplications. In addition, engineering advances in DNA nanodevices at interfaces for improved biosensing both in vitro and in vivo are presented. The use of DNA nanotechnology as a tool to engineer cell membranes to reveal protein levels and cell behavior is also discussed. Finally, we present challenges and an outlook for this emerging field.

Abstract
Herein, we report a bottom-up approach to assemble a series of stochastic DNA walkers capable of probing dynamic interactions occurring at the bio-nano interface. We systematically investigated the impact of varying interfacial factors, including intramolecular interactions, orientation, cooperativity, steric effect, multivalence, and binding hindrance on enzymatic behaviors at the interfaces of spherical nucleic acids. Our mechanistic study has revealed critical roles of various interfacial factors that significantly alter molecular binding and enzymatic behaviors from bulk solutions. The improved understanding of the bio-nano interface may facilitate better design and operation of nanoparticle-based biosensors and/or functional devices. We successfully demonstrate how improved understanding of the bio-nano interface help rationalize the design of amplifiable biosensors for nucleic acids and antibodies.

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
Extracellular vesicles (EVs) play important roles in cell-cell communication by transferring cargo proteins and nucleic acids between cells. Due to their small size (50-150 nm) and low density, rapid capture and nondestructive release of EVs remains a technical challenge which significantly hinders study of their biofunction and biomedical application. To address this issue, we designed a DNA aptamer-based system that enabled rapid capture and nondestructive release of EVs in 90 min with similar isolation efficiency to ultracentrifugation (around 78%). Moreover, because we designed a DNA structure-switch process to release the exosomes, the isolated EVs maintained high bioactivity in cell-uptake assay and wound-healing assays. Using this method, we can isolate EVs from clinical samples and found that the amount of MUC1 positive EVs in breast cancer patient plasma sample is significantly higher than that in healthy donors. This DNA aptamer-based magnetic isolation strategy can be potentially applied for the biofunction study of EVs and EV-based point-of-care clinical tests.

Abstract
Specific nucleic acid detection in vitro or in vivo has become increasingly important in the discovery of genetic diseases, diagnosing pathogen infection and monitoring disease treatment. One challenge, however, is that the amount of target nucleic acid in specimens is limited. Furthermore, direct sensing methods are also unable to provide sufficient sensitivity and specificity. Fortunately, due to advances in nanotechnology and nanomaterials, nanotechnology-based bioassays have emerged as powerful and promising approaches providing ultra-high sensitivity and specificity in nucleic acid detection. This chapter presents an overview of strategies used in the development and integration of nanotechnology for nucleic acid detection, including optical and electrical detection methods, and nucleic acid assistant recycling amplification strategies. Recent 5 years representative examples are reviewed to demonstrate the proof-of-concept with promising applications for DNA/RNA detection and the underlying mechanism for detection of DNA/RNA with the higher sensitivity and selectivity. Furthermore, a brief discussion of common unresolved issues and future trends in this field is provided both from fundamental and practical point of view.

Abstract
Individual (bio)chemical entities could show a very heterogeneous behaviour under the same conditions that could be relevant in many biological processes of significance in the life sciences. Conventional detection approaches are only able to detect the average response of an ensemble of entities and assume that all entities are identical. From this perspective, important information about the heterogeneities or rare (stochastic) events happening in individual entities would remain unseen. Some nanoscale tools present interesting physicochemical properties that enable the possibility to detect systems at the single-entity level, acquiring richer information than conventional methods. In this review, we introduce the foundations and the latest advances of several nanoscale approaches to sensing and imaging individual (bio)entities using nanoprobes, nanopores, nanoimpacts, nanoplasmonics and nanomachines. Several (bio)entities such as cells, proteins, nucleic acids, vesicles and viruses are specifically considered. These nanoscale approaches provide a wide and complete toolbox for the study of many biological systems at the single-entity level.
