Abstract
The silicon nanowire field-effect transistor (SiNW FET) has been developed for over two decades as an ultrasensitive, label-free biosensor for biodetection. However, inconsistencies in manufacturing and surface functionalization at the nanoscale have led to poor sensor-to-sensor consistency in performance. Despite extensive efforts to address this issue through process improvements and calibration methods, the outcomes have not been satisfactory. Herein, based on the strong correlation between the saturation response of SiNW FET biosensors and both their feature size and surface functionalization, we propose a calibration strategy that combines the sensing principles of SiNW FET with the Langmuir-Freundlich model. By normalizing the response of the SiNW FET biosensors (ΔI/I0) with their saturation response (ΔI/I0)max, this strategy fundamentally overcomes the issues mentioned above. It has enabled label-free detection of nucleic acids, proteins, and exosomes within 5 min, achieving detection limits as low as attomoles and demonstrating a significant reduction in the coefficient of variation. Notably, the nucleic acid test results exhibit a strong correlation with the ultraviolet-visible (UV-vis) spectrophotometer measurements, with a correlation coefficient reaching 0.933. The proposed saturation response calibration strategy exhibits good universality and practicability in biological detection applications, providing theoretical and experimental support for the transition of mass-manufactured nanosensors from theoretical research to practical application.

Abstract
Liquid biopsy is a non-invasive diagnostic method that can reduce the risk of complications and offers exceptional benefits in the dynamic monitoring and acquisition of heterogeneous cell population information. Optical nanomaterials with excellent light absorption, luminescence, and photoelectrochemical properties have accelerated the development of liquid biopsy technologies. Owing to the unique size effect of optical nanomaterials, their improved optical properties enable them to exhibit good sensitivity and specificity for mitigating signal interference from various molecules in body fluids. Nanomaterials with biocompatible and optical sensing properties play a crucial role in advancing the maturity and diversification of liquid biopsy technologies. This article offers a comprehensive review of recent advanced liquid biopsy technologies that utilize novel biocompatible optical nanomaterials, including fluorescence, colorimetric, photoelectrochemical, and Raman broad-spectrum-based biosensors. We focused on liquid biopsy for the most significant early biomarkers in clinical medicine, and specifically reviewed reports on the effectiveness of optical nanosensing technology in the detection of real patient samples, which may provide basic evidence for the transition of optical nanosensing technology from engineering design to clinical practice. Furthermore, we introduced the integration of optical nanosensing-based liquid biopsy with modern devices, such as smartphones, to demonstrate the potential of the technology in portable clinical diagnosis.

Abstract
MicroRNA (miRNA) is an important biomarker for early diagnosis of cancers. However, sensitive and convenient methods for miRNA detection remain a challenge. Here, we use a natural biopolymer sporopollenin purified from Ganoderma lucidum spores as a substrate for isothermal amplification (hybridization chain reaction, HCR). Sporopollenin capsules (SP) promotes HCR and forms longer and more abundant double-stranded DNA (dsDNA) than graphene oxide (GO) and carbon nanotubes (CNTs). The nanoporous structure of sporopollenin capsules containing abundant water provides a hydrous environment and enhances the hybridization efficiency of DNA significantly. We construct an ultrasensitive fluorescent biosensor to detect miR-155. The efficient HCR amplification on SP leads to an ultralow detection limit of 1 aM for miR-155 and a wide linear range of 1 aM-10 fM (R2 = 0.99). Furthermore, our fluorescence biosensor can discriminate miRNA mutants with high selectivity. This biosensor is also highly sensitive in human serum (detection limit 10 aM). It adsorbs less serum protein than GO and CNTs, thus minimizing the interference caused by the non-specific adsorption. Our study would promote medical application of SP-based biosensor in the future.

Abstract
A cascade signal-amplified fluorescent biosensor was developed for miRNA-21 detection by combining APE1 enzyme-assisted target recycling and rolling circle amplification strategy. A key feature of this biosensor is its dual-trigger mechanism, utilizing both tumor-endogenous miRNA-21 and the APE1 enzyme in the initial amplification step, followed by a second rolling circle amplification reaction. This dual signal amplification cascade significantly enhanced sensitivity, achieving a detection limit of 3.33 pM. Furthermore, this biosensor exhibited excellent specificity and resistance to interference, allowing it to effectively distinguish and detect the target miRNA-21 in the presence of multiple interfering miRNAs. Moreover, the biosensor maintained its robust detection capabilities in a 10% serum environment, demonstrating its potential for clinical disease diagnosis applications.

Abstract
Many microRNAs (miRNAs) are characteristically found in cancer cells, making miRNAs promising marker biomolecules for cancer diagnosis and therapeutics. However, it is challenging to use miRNA as a cancer signature because it is difficult to convert the nucleic acid sequence information into molecular functionality. To address this challenge, we realize nucleic acid-to-small molecule converters using hairpin DNA circuits. Harnessing a Staudinger reduction as a trigger for the conversion, we constructed hybridization chain reaction (HCR) and catalytic hairpin assembly (CHA) circuits that respond to oncogenic miR-21. Fluorophore and dye molecules were released in response to miR-21 through the HCR, providing fluorogenic and chromogenic readouts. Selective cytotoxicity in miR-21-abundant cells was realized by the CHA to release the anticancer drug SN-38. This would be the first example of selective activation of a small-molecule prodrug triggered by oncogenic miRNA in human living cells.

Abstract
An ultrasensitive split-type fluorescent immunobiosensor has been reported based on a cascade signal amplification strategy by coupling chemical redox-cycling and Fenton-like reaction. In this strategy, Cu2+ could oxidize chemically o-phenylenediamine (OPD) to generate photosensitive 2, 3-diaminophenazine (DAP) and Cu+/Cu0. On one hand, the generated Cu0 in turn catalyzed the oxidation of OPD. On the other hand, the introduced H2O2 reacted with Cu + ion to produce hydroxyl radicals (·OH) and Cu2+ ion through a Cu + -mediated Fenton-like reaction. The produced ·OH and recycled Cu2+ ion could take turns oxidizing OPD to generate more photoactive DAP, which triggering a self-sustaining chemical redox-cycling reaction and leading to a remarkable fluorescent improvement. It was worth mentioning that the cascade reaction did not stop until OPD molecules were completely consumed. Based on the H2O2-triggered cascade signal amplification, the strategy was exploited for the construction of split-type fluorescent immunoassay by taking interleukin-6 (IL-6) as the model target. It was realized for the ultrasensitive determination of IL-6 in a linear ranging from 20 fg/mL to 10 pg/mL with a limit of detection of 5 fg/mL. The study validated the practicability of the cascade signal amplification on the fluorescent bioanalysis and the superior performance in fluorescent immunoassay. It is expected that the strategy would offer new opportunities to develop ultrasensitive fluorescent methods for biosensor and bioanalysis.

Abstract
MicroRNA-21 (miRNA-21) is a kind of RNA that exists in biological fluids such as blood, urine and saliva. It has over expression in liver cancer and has different expression in different stages of cancer. However, due to the characteristics of small base number, short length, low abundance and easy degradation of miRNA-21, the detection of miRNA-21 is a challenging subject. Visualization, sensitive, specific and stable detection of tumor suppressor or oncogene microRNAs (miRNAs) remains challenging and is highly significant for clinical diagnostics. To solve this problem, we have developed a target-triggered hybridization assembly DNA machine for intracellular miRNA imaging based on strand displacement amplification (SDA) and branched hybridization chain reaction (B-HCR). In this approach, the target miRNA could hybridize with the template probe to trigger the SDA, resulting in the formation of nicked fragments (NFs) that hybridized with hairpin probe1 (HP1). The opened HP1 could hybridize with hairpin probe2 (HP2), leading to the self-assembly of hyperbranched DNA nanostructures through B-HCR. As expected, the newly developed method exhibits a detection limit down to 11.3 pM miRNA-21 and achieves high selectivity toward miRNA-21 against other interfering miRNAs. Due to its superior sensitivity and selectivity, our method can be further used to detect miRNA-21 in human serum samples. By taking advantage of intelligent design, the proposed method was also used for image miRNA-21 expression levels in different cell lines. This method shows a broad application in clinical diagnosis.

Abstract
It is important to develop effective strategies to construct enzymatic biofuel cell based self-powered biosensors. We report here the facile regulation of enzymatic loading capacity on the bioanode by utilizing a concatenated catalytic hairpin assembly (CHA)/hybridization chain reaction (HCR) and its application for self-powered microRNA-141 (miRNA-141) detection. To construct the bioanode, a concatenated CHA/HCR process triggered by miRNA-141 was conducted on the three-dimensional macroporous gold (3DMG) electrode to generate long double-stranded DNA nanowires for glucose oxidase immobilization. Quartz crystal microbalance study reveals that the enzymatic loading capacity on the bioanode increases at an increasing miRNA-141 concentration, leading to enhanced catalytic performance for glucose oxidation. The short-circuit currents of the assembled glucose/O2 biofuel cells increase at increasing miRNA-141 concentrations, enabling ultrasensitive detection of miRNA-141. The self-powered biosensor features a wide dynamic range for detecting miRNA-141 from 10-17 to 10-11 M, with an ultralow detection limit of 1.3 aM. This work provides a highly sensitive self-powered biosensing platform for miRNA detection.

Abstract
A novel, simple, and sensitive quantitative polymerase chain reaction (qPCR) technology, which is termed as helper qPCR, was established to detect miRNA. In this assay, the target miRNA sequence was introduced as helper template for a reaction switch preforming two-step real-time qPCR strategy. Firstly, the reverse primer was reverse transcribed to form “mediator primer” after binding to the target miRNA. Then, the mediator primer was further extended to form “active template” with annealing to the mediator template. In the end, the active template was amplified and detected by the qPCR reaction system with the help of reverse and forward primers. The SYBR Green dye was used for fluorescence quantification, which is quicker and cheaper than the fluorescent probes, as the detection limit of this assay was 1 pM. This helper qPCR system can be used for different miRNAs detection by redesigning reverse primer for target, indicating this strategy could afford good performance in detecting multiple miRNAs and has a promising application prospect.

Abstract
Fluorescence anisotropy/polarization is an attractive and versatile technique based on molecular rotation in biochemical/biophysical systems. Traditional fluorescence anisotropy/polarization assays showed relatively low sensitivity for molecule detection, because widespread molecular masses are too small to produce detectable changes in fluorescence anisotropy/polarization value. In this review, we discuss in detail how the potential of fluorescence anisotropy/polarization signal approach considerably expanded through the implementation of mass amplification, recycle the target amplification, fluorescence probes structure-switching amplification, resonance energy transfer amplification, and provide perspectives at future directions and applications.

Abstract
Abnormal expression of miRNAs is often detected in various human cancers. DNAzyme machines combined with gold nanoparticles (AuNPs) hold promise for detecting specific miRNAs in living cells but show short circulation time due to the fragility of catalytic core. Using miRNA-21 as the model target, by introducing a circular bulging DNA shield into the middle of the catalytic core, we report herein a self-protected DNAzyme (E) walker capable of fully stepping on the substrate (S)-modified AuNP for imaging intracellular miRNAs. The DNAzyme walker exhibits 5-fold enhanced serum resistance and more than 8-fold enhanced catalytic activity, contributing to the capability to image miRNAs much higher than commercial transfection reagent and well-known FISH technique. Diseased cells can accurately be distinguished from healthy cells. Due to its universality, DNAzyme walker can be extended for imaging other miRNAs only by changing target binding domain, indicating a promising tool for cancer diagnosis and prognosis.

Abstract
The expression level of nucleic acids is closely related to a variety of diseases. Herein, a highly sensitive detection of a nucleic acid based on a CoOOH-luminol chemiluminescence (CL) system without the addition of oxidants was proposed by the toehold-mediated strand displacement reaction (TSDR) and the liposome dual signal amplification strategy with the hybrid probe formed by linking soft nanoballs (SNBs) to magnetic beads (MBs) through DNA hybridization. Inspired by the free radical scavenging effect of the as-prepared carbon dots (CDs), CDs were successfully employed to quench the CL intensity of the CoOOH-luminol system. And the CDs were further encapsulated into liposomes to construct SNBs, which avoided the complex modification of CDs to maintain their original properties, as well as loaded a large number of CDs to scavenge free radicals to achieve signal amplification. Based on this, target DNA (tDNA) could be sensitively detected based on the reduced CL intensity, which achieved a dynamic detection range from 0.1 nM to 20 nM with a limit of detection as low as 59 pM (3σ/k), showing amazing promise in the biosensing of nucleic acid biomarkers.

Abstract
MicroRNAs (miRNAs) are found in extremely low concentrations in cells, so highly sensitive quantitation is a great challenge. Herein, a simple dual-amplification strategy involving target-activated catalytic hairpin assembly (CHA) coupled with multiple fluorophores concentrated on one X-shaped DNA is reported. In this strategy, four hairpin probes (H1, H2, H3, and H4) are modified with FAM and BHQ1 at both sticky ends, while a circulating hairpin probe (H0) is used to activate CHA circuits once it binds to complementary sequences in the target miR-21 (T). The powerful dual-amplification cascades in Förster resonance energy transfer (FRET)-based nonenzymatic nucleic acid circuits are triggered by T-H0-activated formation of the X-shaped DNA nanostructure, freeing T-H0 for the next CHA reaction cycle. CHA circuits increase the fluorescence due to the wide distance between FAM and BHQ1 in the formed X-shaped DNA nanostructure, resulting in signal amplification and highly sensitive detection of miR-21, with a limit of detection (LOD, 3σ) of 0.025 nM, which is 25.6 or 57.6 times lower than that obtained through a single-amplification strategy without multiple fluorophores on one X-shaped DNA or CHA circuit. Furthermore, this cascade reaction was completed in 45 min, effectively avoiding target degradation. This new enzyme-free signal amplification strategy holds promising potential for sensitively detecting different DNA or RNA sequences by simply adapting the fragment of the H0 sequence complementary to the target.

Abstract
Single-cell microRNA (miRNA) analysis helps people understand the causes of diseases and formulate new disease treatment strategies. However, miRNA from a single cell is usually very rare and requires signal amplification for accurate quantification. Here, to amplify the signal, we constructed the cascaded DNA circuits consisting of catalytic hairpin assembly and hybrid chain reaction into the bead array platform, on which the uniformly distributed beads were adopted for miRNA quantification. After exponential signal amplification, a consistent linear correlation between the percentage of fluorescent beads and the copy number of miRNA was detected. The proposed bead array can achieve ultrahigh sensitivity as low as 60 copies of miR-155 and high specificity for distinguishing single nucleotide differences. This method has been successfully applied to the quantitative detection of miRNA in a single cancer cell. The high sensitivity, programmability, and simple workflow of the bead array chip will give a huge advantage in basic and clinical research.

Abstract
A method is presented that uses photoinduced electron transfer (PET) for the determination of microRNAs (miRNAs) in clinical serum samples and complicated cell samples by using a smartphone. miRNA-21 is adopted as a model analyte. A 3'-phosphorylated DNA probe containing AgNCs is synthesized and hybridized with miRNA-21. Subsequently, the probe is cleaved specifically by duplex-specific nuclease to form 3'-hydroxylated products, then extended by terminal deoxynucleotidyl transferase (TdT) with superlong G for G-quadruplex/hemin units fabrication. In this way, PET occurred between AgNCs and produced G-quadruplex/hemin units, leading to the fluorescence quenching of AgNCs. Notably, the fluorescence images can be captured and translated into digital information by smartphone, resulting in a direct quantitative determination of miRNA. As a result, our strategy for miRNA assay is achieved with a satisfactory detection limit of 1.43 pM. Interestingly, TdT-propelled G-quadruplex/hemin units as multiple electron acceptors promote the sensitivity of miRNA monitoring. Different miRNAs assays are realized by adjusting the complimentary sequences of DNA probe. These qualities not only broaden the practical application of PET-based strategy, but also provide a new insight into the nucleic acid detection. Schematic representation of AgNCs and enzyme-propelled photoinduced electron transfer strategy. It has been successfully applied for detection of miRNA by image analysis software. The method displays portability and accuracy for miRNA determination, meeting the potential for biochemical and clinical applications in resource-limited settings.

Abstract
MicroRNA (miRNA) expression is perturbed in various diseases. Herein, we have aimed to develop a novel and rapid fluorescence-based assay for detecting microRNA-21 (miR-21) activity based on FAM molecular signal amplification and graphene oxide (GO) quenching. In this system, a single stranded DNA (ssDNA) with a phosphate group at the 5'-end is labeled with a FAM molecular label at the 3'-end. In the presence of miR-21, this ssDNA forms a DNA/RNA duplex, which is cleaved by λ exonuclease (λ-exo), releasing FAM and resulting in fluorescence signal amplification at 530 nm. However, the DNA/RNA duplex is not generated in the absence of miR-21, which impedes λ-exo cleavage; subsequently, GO quenches the fluorescence intensity. The results show a detection limit of 0.02 nM and a wide linear range of 0.02-5 nM. The high sensitivity and easy operability of this assay can be applied for detecting miR-21 during clinical diagnosis of certain diseases and in biological research.

Abstract
In this work, homo-FRET (Förster resonance energy transfer between the same kind of fluorophores) takes place in a hetero-FRET (FRET between two different fluorophores) system and can effectively improve the energy transfer efficiency. Herein, a novel ratiometric fluorescence method was developed for the detection of nuclease activity. Exonuclease III (Exo III), an enzyme which has a high exodeoxyribonuclease activity for double-stranded DNA (dsDNA) in the 3' to 5' direction, was chosen as a proof of concept of this strategy. In a linear dsDNA template, the occurrence of homo-FRET in two Cy3 donors enables the highly efficient transfer of energy to the Cy5 acceptor. The ratio of fluorescence intensity between Cy3 and Cy5 (FD/FA) increases in an Exo III concentration-dependent manner, which built the foundation of Exo III quantification. This method exhibits a linear range from 0.25 to 8 U mL-1 with a detection limit of 0.17 U mL-1. Importantly, this platform also shows the potential for screening Exo III inhibitors and detecting Exo III activity in complex samples.

Abstract
Protein is an excellent molecular mass amplifier without fluorescence quenching effect for fluorescence anisotropy (FA) assay. However, in traditional protein amplified FA methods, the binding ratio between amplifier and dye-modified probe is 1:1 or one target can only induce FA change of one fluorophore on probe, resulting in low sensitivity. Herein, we developed a simple FA strategy with high accuracy and sensitivity by using a crosslinked submicro-hydrogel that was formed through a catalyzed hairpin assembly (CHA) assisted protein aggregation as a novel FA amplifier. In the presence of catalyst, the CHA process was initiated through the toehold-mediated strand exchange reaction, which led to the formation of a dye and biotin-labeled Y-shaped H1-H2 duplex (YHD) and recycling of catalyst. With the introduction of streptavidin, a crosslinked submicro-hydrogel was formed by strong binding affinity between biotin on YHD and streptavidin, resulting in an increased FA of fluorescent dye. After rational design of the catalyst sequence, this method has been utilized for the detection of miRNA-145, staphylococcal enterotoxin B (SEB) and ATP with an LOD of 2.5 nM, 92 pg mL-1 and 3.6 μM, respectively. Moreover, this FA assay has been successfully applied for direct detection of target in biological samples, demonstrating its practicality in complex biological systems.

Abstract
Effective and simultaneous monitoring of the abnormal expression of certain microRNAs (miRNAs), especially for miRNA-21 and miRNA-155, can indicate drug resistance in lung cancer. In this work, T7 exonuclease (T7 Exo)-assisted target recycling amplification coupled with the extensive fluorescence quenching of graphene oxide (GO) was designed for the simultaneous detection of miRNA-21 and miRNA-155 using FAM- and ROX-labeled single-strand DNA probes. Through this method, the variable emission intensities of FAM and ROX caused by the introduction of miRNA-21 and miRNA-155, respectively, were obtained with high sensitivity. The method exhibited excellent analytical performance for simultaneous detection of miRNA-21 and miRNA-155 without cross-interference. The linear range was from 0.005 nM to 5 nM over three orders of magnitude, with detection limits as low as 3.2 pM and 4.5 pM for miRNA-21 and miRNA-155, respectively. Furthermore, the recovery (92.49-103.67%) and relative standard deviation (RSD < 4.8%) of the standard addition test of miRNA-21 and miRNA-155 in human plasma suggested the potential for drug resistance warning in clinical practice via this simple strategy. A homogeneous T7 Exo-assisted signal amplification combined with GO quenching platform was developed for accurate, sensitive and simultaneous analysis of miRNA-21 and miRNA-155 for drug resistance warning in lung cancer. This simple method exhibited a wide linear range and low LODs for miR-21 and miR-155.

Abstract
The abnormal expression of some miRNAs is often closely related to the development of tumors. Available detection methods or biosensors that can simultaneously quantify multiple miRNAs in a single sample have rarely been reported. Herein, a novel catalytic hairpin self-assembly (CHA)-based surface-enhanced Raman scattering (SERS) sensor array was developed to simultaneously measure multiple miRNAs associated with cancer in one sample. The sensor array with four different sensing units was constructed by immobilizing one of four different hairpin-structured DNA sequence 1 (hp1) onto one of four Au/Ag alloy nanoparticle (AuAgNP)-coated detection wells. When target miRNA is present, the SERS tags, which were prepared by modifying AuAgNPs with a Raman reporter molecule of 4-mercaptobenzonitrile (MPBN) and the related hairpin-structured DNA sequence 2 (hp2), were captured onto the corresponding sensor unit through a repeated specific CHA reaction. This generated many "hot spots" because of interactions between the SERS tags and the AuAgNP layer-coated surface of the sensor, which ultimately produced a strong SERS signal that allowed the detection of target miRNAs with the detection limit of 0.15 pM. Using this SERS sensor array, multiple cancer-associated miRNAs (miR-1246, miR-221, miR-133a, and miR-21) were successfully determined in buffer, serum, and cellular RNA extracts.

Abstract
A comprehensive review of optical biosensors for the detection of biomarkers associated with rheumatoid arthritis (RA) is presented here, including microRNAs (miRNAs), C-reactive protein (CRP), rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA), interleukin-6 (IL-6) and histidine, which are biomarkers that enable RA detection and/or monitoring. An overview of the different optical biosensors (based on fluorescence, plasmon resonances, interferometry, surface-enhanced Raman spectroscopy (SERS) among other optical techniques) used to detect these biomarkers is given, describing their performance and main characteristics (limit of detection (LOD) and dynamic range), as well as the connection between the respective biomarker and rheumatoid arthritis. It has been observed that the relationship between the corresponding biomarker and rheumatoid arthritis tends to be obviated most of the time when explaining the mechanism of the optical biosensor, which forces the researcher to look for further information about the biomarker. This review work attempts to establish a clear association between optical sensors and rheumatoid arthritis biomarkers as well as to be an easy-to-use tool for the researchers working in this field.

Abstract
Herein, we propose a new peroxide test strip (PTS) based point-of-care testing (POCT) method to detect ricin B-chain qualitatively and quantitatively by using catalytic hairpin assembly (CHA) mediated liposome-encoded magnetic beads for signal amplification. The sensitivity of this PTS based POCT method was improved significantly because it combined CHA signal amplification and liposome-based signal amplification.

Abstract
Fluorescence anisotropy (FA) has been widely applied for detecting and monitoring special targets in life sciences. However, matrix autofluorescence restricted its further application in complex biological samples. Herein, we report a near-infrared-II (NIR-II) FA strategy for detecting adenosine triphosphate (ATP) in human serum samples and breast cancer cell lysate, which employed NIR-II fluorescent Ag2Se quantum dots (QDs) as tags to reduce matrix autofluorescence effect and applied graphene oxide (GO) to enhance fluorescence anisotropy signals. In the presence of ATP, the recognition between NIR-II Ag2Se QDs labeled aptamer (QD-pDNA) and ATP led to the release of QD-pDNA from GO, resulting in the obvious decrease of FA values. ATP could be quantitatively detected in concentrations ranged from 3 nM to 2500 nM, with a detection limit down to 1.01 nM. This study showed that the developed NIR-II FA strategy could be applied for detecting targets in complex biological samples and had great potential for monitoring interactions between biomolecules in biomedical research.

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

Abstract
The sensitive and selective detection of biomarkers plays a crucial role in disease diagnostics, drug discovery, and early screening of cancers. The achievement of this goal highly depends on the continuous development of biosensing technologies. Among them, fluorescence anisotropy/polarization (FA/FP) analysis receives increasing interest due to the advantage of simple operation, fast response, and no background interference. In recent decades, great progress has been achieved in FA/FP sensors thanks to the development of functional nucleic acids (FNAs) including aptamers and nucleic acid enzymes. This review focuses on FNA-based FA/FP sensors for the quantitative detection of biomarkers, such as nucleic acid, small molecules, and proteins. The design strategies, recognition elements, and practical applications are fully highlighted. The article also discusses the challenges of applying FNA-based FA/FP sensors in the next generation and the potential solutions along with future prospects. Graphical abstract.

Abstract
Peptide nucleic acids (PNAs), the synthetic DNA mimics that can bind to oligonucleotides to form duplexes, triplexes, and quadruplexes, could be advantageous as probes for nucleic acid sequences owing to their unique physicochemical and biochemical properties. We have found that a homopurine PNA strand could bind to two homopyrimidine DNA strands to form a PNA-DNA2 triplex. Moreover, the cyanine dye DiSC2 (5) could bind with high affinity to this triplex and cause a noticeable color change. On the basis of this phenomenon, we have designed a label-free colorimetric sensing platform for miRNAs from cancer cells by using a PNA-DNA2 triple-helix molecular switch (THMS) and DiSC2 (5). This sensing platform can detect miRNA-21 specifically with a detection limit of 0.18 nM, which is comparable to that of the THMS-mediated fluorescence sensing platform. Moreover, this colorimetric platform does not involve any chemical modification or enzymatic signal amplification, which boosts its applicability and availability at the point of care in resource-limited settings. The universality of this approach can be simply achieved by altering the sequences of the probe DNA for specific targets.

Abstract
We here report a double amplification strategy to construct a fluorescence anisotropy sensor for microRNA analysis in practical biological samples. In this strategy, one target can trigger cyclic catalyzed hairpin assembly (CHA), with streptavidin incorporated as an amplifier of molar mass to enhance the signal intensity. The proposed strategy has a good linearity in the range of 5 pM - 0.5 nM with a detection limit down to 2.3 pM. More importantly, by using fluorescence anisotropy as the signal output, the strategy can be used directly for detection of miRNA in practical samples without any tedious sample pretreatment, holding the practical value in real biological systems.

Abstract
Chondroitin sulfate (CS) plays an increasingly important role in clinical settings and pharmacy quality control. However, sensitive and simple methods for CS detection remain limited. In this work, positively charged nitrogen doped carbon dots (P-NCDs) with internal luminescence and quenching property to FAM-labeled random-sequence ssDNA (F-ssDNA) were prepared by a simple heating method. P-NCDs attached and quenched F-ssDNA through electrostatic interaction to form the system of P-NCDs and F-ssDNA (P-NCDs/F-ssDNA) with retained fluorescence intensity of P-NCDs. The highly negatively charged CS reacted electrostatically with P-NCDs and then replaced F-ssDNA in P-NCDs/F-ssDNA to recover the fluorescence intensity of the original quenched F-ssDNA while retaining the internal fluorescence intensity of P-NCDs. Thus, by using restored F-ssDNA as the signal controlled by adding CS to P-NCDs/F-ssDNA, a ratiometric fluorescence strategy based on the retained fluorescence of P-NCDs as reference signal was fabricated through synchronous fluorescence spectrometry for the sensitive detection of CS. Under the optimal experimental conditions, a linear equation for CS was obtained for CS concentration within the range of 0.05-2.0 μg/mL. The method was also successfully applied for the accurate determination of CS in joint fluid samples of arthritic patients, chondroitin sulfate tablets, and chondroitin sulfate eye drops, suggesting its appreciable application potential in the clinic.

Abstract
Recently, various inorganic nanomaterials have been used as fluorescence anisotropy (FA) enhancers for biosensing successfully. However, most of them are size-uncontrollable and possess an intensive fluorescence quenching ability, which will seriously reduce the accuracy and sensitivity of FA method. Herein, we report a two-dimensional DNA nanosheet (DNS) without fluorescence quenching effect as a novel FA amplification platform. In our strategy, fluorophore-labeled probe DNA (pDNA) is linked onto the DNS surface through the hybridization with the handle DNA (hDNA) that extended from the DNS, resulting in the significantly enhanced FA value. After the addition of target, the pDNA was released from the DNS surface due to the high affinity between the hDNA and target, and the FA was decreased. Thus, target could be detected by the significantly decreased FA value. The linear range was 10-50 nM and the limit of detection was 8 nM for the single-stranded DNA detection. This new method is general and has been also successfully applied for the detection of ATP and thrombin sensitively. Our method improved the accuracy of FA assay and has great potential to detect series of biological analytes in complex biosensing systems.

Abstract
A simple and label-free sensing platform with low background based on the chain-displacement triggered self-assembly of Ag NCs was developed for ratiometric visual analysis of intracellular miRNA-21. Based on this sensitively ratiometric sensing approach, a picomole limit detection for miRNA-21 can be obtained. Most importantly, compared with the traditional single base mismatch detection method, our proposed method can realize single base mismatch detection according to the remarkable fluorescence color conversion, rather than simple fluorescence intensity change, which can obviously improve the accuracy and reliability. In addition, successful multicolor real-time monitoring of intracellular miRNA-21 makes the probe a potential candidate for miRNA-21 inhibiting drug screening. Furthermore, MCF-7, HeLa, and normal L02 cells can also be visually differentiated according to the fluorescence color by using the label-free sensing platform, showing its potential prospect in target visual analysis.
