Abstract
The rapid and accurate detection of miRNAs is of great significance for early diagnosis and treatment of cancer. Hence, a novel enzyme-free and label-free electrochemical biosensor based on bio-barcode amplification for detecting miRNAs was presented. Sandwich structures constructed of magnetic nanoparticles modified with DNA probes, gold nanoparticles with numerous barcoded DNA strands that hybridized with target miRNAs were fabricated as the amplifier. The released barcoded DNA strands then acted as the secondary targets and triggered the electrochemical sensor with a significant electrochemical response. A highly sensitive (detection limit of 0.24 fM) and selective electrochemical miRNA detection was realized, which has great potential for application in miRNA-related clinical diagnosis and biochemical research.

Abstract
Tumor-derived exosome (TD-Ex) serves as a crucial early diagnostic biomarker of pancreatic cancer (PC). However, accurate identification of TD-Ex from PC is still a challenging work. In this paper, a detection microsystem that integrates magnetic separation and FET biosensor is developed, which is capable of selectively separating TD-Ex of PC from the plasma and detecting exosomal miRNA10b in a sensitive and specific manner. The magnetic beads were functionalized with dual antibody (GPC-1 antibody and EpCAM antibody), enabling selective recognition and capture of PC-derived exosomes. On the other hand, a peptide nucleic acid (PNA)- functionalized reduced graphene oxide field-effect transistor (RGO FET) biosensor was subsequently utilized to detect the exosomal miRNA10b, which is highly expressed in PC- derived exosomes. This system could achieve a low detection limit down to 78 fM, and selectively identify miRNA10b from single-base mismatched miRNA. In addition, 40 clinical plasma samples were tested with this microsystem, and the results indicate that it could effectively distinguish PC patients from healthy individuals. The assay combines specific capture and enrichment of PC-derived exosomes with sensitive and selective detection of exosomal miRNA, showing its potential to be used as an effective scheme for PC early diagnosis.

Abstract
Exosomes are extracellular vesicles, which have the ability to convey various types of cargo between cells. Lately, a great amount of interest has been paid to exosomal microRNAs (miRNAs), since much evidence has suggested that the sorting of miRNAs into exosomes is not an accidental process. It has been shown that exosomal miRNAs (exo-miRNAs) are implicated in a variety of cellular processes including (but not limited to) cell migration, apoptosis, proliferation, and autophagy. Exosomes can play a role in cardiovascular diseases and can be used as diagnostic biomarkers for several diseases, especially cancer. Tremendous advances in technology have led to the development of various platforms for miRNA profiling. Each platform has its own limitations and strengths that need to be understood in order to use them properly. In the current review, we summarize some exo-miRNAs that are relevant to exo-miRNA profiling studies and describe new methods used for the measurement of miRNA profiles in different human bodily fluids.

Abstract
In this paper preliminarily verified that graphene oxide (GO) nanomaterials enhanced the recombinase polymerase amplification (RPA). GO nanosheets improved the efficiency of RPA amplification by absorbing ingredients to induce local aggregation. The recombinase initially aggregated with the primers to form nucleoprotein filaments, absorbed on the GO nanosheets, changing the structure. Therefore, an isothermal fluorescence biosensor was developed based on GO nanosheets enhanced the RPA to detect RNA interference (RNAi) transgenic plants. FAM-labeled primers were absorbed and quenched by the GO nanosheets. After amplification, the primers were extended into double-stranded DNA, detaching from the GO surface to recover the fluorescent signal. The biosensor displayed high sensitivity and selectivity and showed an excellent relationship ranging from 1.5 to 100 ng of genome DNA, with a detection limit (LOD) of 1.5 ng. Consequently, the biosensor provides an enhanced isothermal method for detecting genetically modified (GM) products and exhibits significant potential for molecular detection.

Abstract
The glioma is the most malignant form of brain cancer and the glioma cells could communicate with tumor microenvironment to tune it for benefits through sEVs based way. Therefore, detection of sEVs surface protein may contribute to the early diagnosis of glioma. We proposed here a isothermal and rapid amplification sEVs surface protein analysis method. In the method, an elegantly designed capture probe which is composed of surface protein specific aptamer and partially complementary blocker. In addition, the method exhibited a favorable detection performance in both quantification of sEVs and surface protein analysis. In summary, the method would be very useful to detect sEVs in point-of-care and thus contribute to the diagnosis and treatment of glioma.

Abstract
Exosomal microRNAs (miRNAs) derived from different cells are proposed to be important noninvasive biomarkers for the diagnosis of cardiovascular disease. Recently, sensitive and reliable sensing of exosomal miRNAs has been garnered significant attention. Herein, a novel electrochemical biosensor based on a step polymerization catalytic hairpin assembly (SP-CHA) circuit is designed for exosomal miR-181 detection. Exosomal miR-181 as a trigger, induced SP-CHA process and generated a large number of T shaped concatemers with different length on the electrode surface. These ultra-concatemers could provide a much enhanced signal-to-noise ratio with the linear range from 10 fM to 100 nM and the detection limit of 7.94 fM. Furthermore, this assay was successfully applied to the detection of exosomal miR-181 in serum samples of normal healthy controls and patients with coronary heart disease (CHD) and the results were consistent with those analysis collected from qRT-PCR. The assembly demonstrated great performance in differentiating CHD patients from healthy controls (AUC:0.9867). Collectively, this sensing system possessed high stability and sensitivity with ease of operation and cost efficiency, leading to great potential for exosomal miRNAs detection in cardiovascular disease.

Abstract
Herein, a simple all-in-one biosensor based on a DNA three-way junction has been constructed for in situ simultaneous detection of multiple miRNAs by competitive strand displacement. In our design, three oligonucleotides (Y1, Y2 and Y3) of a Y-type scaffold were extended at their 5' ends by introducing three single-stranded recognition sequences with quenchers (BHQ1, BHQ2 and BHQ2), respectively. Subsequently, three reporter sequences labeled with different fluorophores (FAM, Cy3 and Cy5) were bound to the corresponding recognition sequences to form a multicolour DNA biosensor that gives self-quenched fluorescence. The biosensor can effectively enter into exosomes and then hybridize to the complementary miRNA targets to form longer duplexes and release the reporter sequences, thus activating the readable fluorescence signals for the simultaneous detection of multiple miRNAs in exosomes. As a proof of principle, miR-21, miR-27a and miR-375 were chosen as model targets because of their high expressions in breast cancer cells (MCF-7). Fluorescence signals of MCF-7 exosomes after being treated with the biosensor exhibited positive correlations to their concentrations and the limits of detection were determined to be 0.116 μg mL-1, 0.125 μg mL-1 and 0.287 μg mL-1 for exosomes by detecting three exosomal miRNAs (miR-21, miR-27a and miR-375), respectively. In contrast, there were no obvious correlations between fluorescence intensities and control MCF-10A exosome concentrations. Importantly, by testing multiple exosomal miRNAs using the biosensor in clinical serum samples, breast cancer patients can be effectively differentiated from healthy donors. Consequently, the developed biosensor demonstrates high potential as a routine bioassay for the multiplex quantification of exosomal miRNAs in clinical diagnosis.

Abstract
MicroRNAs (miRNAs) in cancer cell-derived exosomes are important cancer biomarkers. Herein, a sensitive hybridization chain reaction (HCR) electrochemical assay was fabricated for the detection of exosomal microRNA-122 (miR-122). The hairpin DNA (hpDNA) probes were first immobilized on the surface of a gold electrode. In the presence of miR-122, the hairpin structure of the hpDNA could be opened and triggered the HCR through the cross-opening and hybridization of two helper DNA hairpins. Long nicked double helixes generated from HCR are used to capture more RuHex and increase the signal of differential pulse voltammetry (DPV). In this assay, the density of the hpDNA probes on the surface of the gold electrode was precisely controlled by the simultaneous immobilization of hpDNA and short 12 nucleotides single-stranded DNA (S-12), providing a very high amplification efficiency. More importantly, the false positive signal could be reduced or completely eliminated by applying exonuclease I (Exo I) before the introduction of target miR-122. Under optimal conditions, the assay offers very high sensitivity with an attomolar level detection limit, a linear range with 9 orders of magnitude, and specificity in single mismatch discrimination. This sensitive electrochemical assay could successfully evaluate the miR-122 concentration in different cancer-derived exosomes, indicating its potential use in cancer diagnostics.

Abstract
Exosomal microRNAs are essential in intercellular communications and disease progression, yet it remains challenging to quantify the expression level due to their small size and low abundance in blood. Here, we report a "sandwich" electrochemical exosomal microRNA sensor (SEEmiR) to detect target microRNA with high sensitivity and specificity. In SEEmiR, neutrally charged peptide nucleic acid (PNA) enables kinetically favorable hybridization with the microRNA target relative to negatively charged DNA, particularly in a short sequence (10 nt). More importantly, this property allows PNA to cooperate with a spherical nucleic acid (SNA) nanoprobe that heavily loads with oligonucleotide-adsorbed electroactive tags to enhance detection sensitivity and specificity. Such a PNA-microRNA-SNA sandwich construct is able to minimize the background noise via PNA, thereby maximizing the SNA-mediated signal amplification in electrostatic adsorption-based SEEmiR. The synergy between PNA and SNA makes the SEEmiR sensor able to achieve a broad dynamic range (from 100 aM to 1 nM) with a detection limit down to 49 aM (2 orders of magnitude lower than that without SNA) and capable of distinguishing a single-base mismatch. This ultrasensitive sensor provides label-free and enzyme-independent microRNA detection in cell lysates, unpurified tumor exosomal lysates, cancer patients' blood, and accurately differentiates the patients with breast cancer from the healthy ones, suggesting its potential as a promising tool in cancer diagnostics.

Abstract
Non-coding RNAs (ncRNAs) participate in regulation of gene expression, and are highly relevant to pathological development. They are found to be stably present in diverse body fluids, including those in the circulatory system, which can be sampled non-invasively for clinical tests. Thus, circulating ncRNAs have great potential to be disease biomarkers. However, tremendous efforts are desired to discover and utilize ncRNAs as biomarkers in clinical diagnosis, calling for technological advancement in analysis of circulating ncRNAs in biospecimens. Hence, this review summarizes the recent developments in this area, highlighting the works devoted to cancer diagnosis and prognosis. Three main directions are focused: 1) Extraction and purification of ncRNAs from body fluids; 2) Quantification of the purified circulating ncRNAs; and 3) Microfluidic platforms for integration of both steps to enable point-of-care diagnostics. These technologies have laid a solid foundation to move forward the applications of circulating ncRNAs in disease diagnosis and cure.

Abstract
Uracil-DNA glycosylase (UDG) is a crucial damage repair enzyme that initiates the cellular base excision repair pathway that maintains the integrity of the genome. Abnormal UDG activity may induce the malfunction of uracil excision repair that is directly related to a range of diseases including cancers, genotypic diseases, and human immunodeficiencies. In this work, a simple, robust and cost effective biosensing platform for the ultrasensitive detection of UDG activity is established based on the combination of base excision repair-initiated primer generation for rolling circular amplification (RCA) with Endo IV-assisted signal amplification. In the presence of target UDG, UDG can catalyze the removal of uracil on a hairpin probe (HP) leaving an apurinic/apyrimidinic (AP site) which can be cleaved by Endo IV to generate a primer for triggering the RCA reaction. Subsequently, numerous AP site-embedded signal probes, acting as fluorescence-quenched probes, combine with the RCA products to perform signal transduction and quadradic signal amplification through an Endo IV-catalyzed cleavage reaction, thus significantly enhancing the fluorescence signal, which can be used for UDG activity screening. Under optimum conditions, this biosensor exhibits improved sensitivity toward target UDG with a detection limit of as low as 9.3 × 10-5 U mL-1 and a wide detection range across 5 orders of magnitude. Additionally, our biosensor demonstrates high selectivity toward UDG for simple, rapid, and low-cost detection. Furthermore, by redesigning the modification of HP and using of suitable endonuclease enzymes, this RCA coupled with Endo IV-assisted signal amplification strategy might be applied for the detection of various other targets, such as thymine DNA glycosylase, 8-oxoguanine DNA glycosylase, DNA methyltransferase, and so on. Hence, the proposed strategy provides a useful and versatile biosensing platform for the ultrasensitive detection of UDG activity and related fundamental biomedicine research and clinical diagnosis.

Abstract
Recently, sensitive and selective detection of exosomal microRNAs (miRNAs) has been garnering significant attention, because it is related to many complex diseases, including cancer. Herein, we report a ratiometric fluorescent bioprobe based on DNA-labeled carbon dots (DNA-CDs) and 5,7-dinitro-2-sulfo-acridone (DSA) coupling with the target-catalyzing signal amplification for the detection of exosomal miRNA-21. There was high fluorescence resonance energy transfer (FRET) efficiency between carbon dots (CDs) and DSA when the bioprobe was assembled. However, in the presence of the target, with disassembling of the fluorescent bioprobe, the fluorescence intensities of CDs and DSA were changed simultaneously. Because of the ratio of dual fluorescence intensities, this ratiometric fluorescent bioprobe was able to cancel out environmental fluctuations by calculating emission intensity ratio at two different wavelengths, being robust and stable enough for detection of exosomal miRNA-21. In addition, we displayed that a single miRNA-21 can catalyze the disassembly of multiple CDs with DSA theoretically, yielding significant change in the fluorescence ratio for the detection of miRNA-21. With this signal amplification strategy, the limit of detection was as low as 3.0 fM. Furthermore, because of the introduction of lock nucleic acid to mediate the strand displacement reaction, the selectivity of this strategy was improved remarkably, even against single base mismatch sequence. More importantly, our strategy could monitor the dynamic change of exosomal miRNA-21, which maybe becomes a potential tool to distinguish cancer exosomes and nontumorigenic exosomes. In a short, this ratiometric fluorescence bioprobe possessed high stability, sensitivity and selectivity coupling with ease of operation and cost efficiency, leading to great potential for wide application.
