Abstract
The clustered regularly interspaced short palindromic repeat/Cas (CRISPR/Cas) system is a powerful tool for nucleic acid detection owing to specific recognition as well as cis- and trans-cleavage capabilities. However, the sensitivity of CRISPR/Cas-based diagnostic approaches is determined by nucleic acid preamplification, which has several limitations. Here, we present a method for direct nucleic acid detection without preamplification, by combining the CRISPR/Cas12a system with signal enhancement based on light-up RNA aptamer transcription. We first designed two DNA templates to transcribe the light-up RNA aptamer and kleptamer (Kb) RNA: the first DNA template encodes a Broccoli RNA aptamer for fluorescence signal generation, and the Kb DNA template comprises a dsDNA T7 promoter sequence and an ssDNA sequence that encodes an antisense strand for the Broccoli RNA aptamer. Hepatitis B virus (HBV) target recognition activates a CRISPR/Cas12a complex, leading to the catalytic cleavage of the ssDNA sequence. Transcription of the added Broccoli DNA template can then produce several Broccoli RNA aptamer transcripts for fluorescence enhancement. The proposed strategy exhibited excellent sensitivity and specificity with 22.4 fM detection limit, good accuracy, and stability for determining the target HBV dsDNA in human serum samples. Overall, this newly designed signal enhancement strategy can be employed as a universal sensing platform for ultrasensitive nucleic acid detection.

Abstract
DNA with programmable information can be used to encode the spatial organization of silver atoms. Based on the primary structures of a DNA template containing a controllable base arrangement and number, the surrounding environment and cluster together can induce the folding of the DNA template into an appropriate secondary structure for forming AgNCs with different fluorescence emissions, such as i-motif, G-quadruplex, dimeric template, triplex, monomeric or dimeric C-loop, emitter pair, and G-enhancer/template conjugate. Stimuli can induce the dynamic structural transformation of the DNA template with a recognition site for favourably or unfavourably forming AgNCs, along with varied fluorescence intensities and colours. The array of several or more of the same and different clusters can be performed on simple and complex nanostructures, while maintaining their original properties. By sorting out this review, we systematically conclude the link between the performance of AgNCs and the secondary structure of the DNA template, and summarize the precise arrangement of nanoclusters on DNA nanotechnology. This clear review on the origin and controllability of AgNCs based on the secondary structure of the DNA template is beneficial for exploring the new probe and optical devices.

Abstract
The chemical composition of cells at the molecular level determines their growth, differentiation, structure, and function. Probing this composition is powerful because it provides invaluable insight into chemical processes inside cells and in certain cases allows disease diagnosis based on molecular profiles. However, many techniques analyze fixed cells or lysates of bulk populations, in which information about dynamics and cellular heterogeneity is lost. Recently, nucleic-acid-based probes have emerged as a promising platform for the detection of a wide variety of intracellular analytes in live cells with single-cell resolution. Recent advances in this field are described and common strategies for probe design, types of targets that can be identified, current limitations, and future directions are discussed.

Abstract
To enhance the specificity and sensitivity of molecular beacons (MBs) in detecting mRNA in living tumor cells, we introduced an aptamer (AS1411) to the delivery system of MBs to form an aptamer-decorated nanoprobe (ANP), which was prepared through self-assembly between AS1411-conjugated carboxymethyl chitosan (ACMC) with protamine sulfate (PS)/CaCO3/MB cores. Owing to the specific binding of AS1411 to nucleolin, which is overexpressed in tumor cell membranes and nuclei, an AS1411-decorated MB-delivery system leads to dramatically increased cell uptake of MBs for probing survivin mRNA and thus induces strong intracellular fluorescence emission in targeted tumorous cells and cell nuclei. Furthermore, we demonstrate that ANP can efficiently detect survivin mRNA in mitochondria. In other words, the effective delivery of MBs ensures the precise detection of mRNA distribution in diverse organelles. In addition, we evaluated the efficiency of ANP in probing tumor cells in simulated blood as well as in peripheral blood from a healthy donor and found that the nanoprobe can specifically deliver MBs to tumor cells and identify tumor cells in blood. The targeting delivery system we constructed holds promising applications in precise detection of subcellular distribution of mRNA in living tumor cells as well as in fluorescence-guided cancer detection in liquid biopsy technology. This study provides a facile strategy to effectively improve the specificity and sensitivity of conventional molecular beacons.

Abstract
In this work, a label-free Ag nanocluster (AgNC)-based fluorescent probe is proposed to detect tumor marker, prostate-specific antigen (PSA). In the experiments, DNA sequences containing segments complemented to different parts of PSA aptamer were used to synthesize DNA-Ag nanoclusters (DNA-AgNC). Some of the obtained specific DNA-AgNC exhibited significant fluorescence increase after hybridization with PSA aptamer. Based on this, a simple DNA-AgNC/aptamer hybridization probe was fabricated for PSA detection using fluorescence quenching, because competitively specific binding between PSA and its aptamer inhibited the fluorescence enhancement effect of PSA aptamer on DNA-AgNC. The sequence of template DNA, pH and salt concentration of binding buffer, and the concentration of aptamer were optimized. Under optimum conditions, the concentration of PSA within the range of 2-150 ng mL-1 with the detection limit of 1.14 ng mL-1 was detected (3σ; n = 7). This approach was also successfully applied to determine PSA in spiked serum samples. As is well known, this was the first report to realize PSA detection using fluorescent AgNC-based probe. This work would provide reference for construction of AgNC-based probes for detecting other proteins.

Abstract
A label-free and sensitive fluorescence biosensing platform for human immunodeficiency virus gene (HIV-DNA) detection has been fabricated based on luminescent DNA-scaffolded silver nanoclusters (DNA/AgNCs) and autonomous exonuclease III (Exo III)-assisted recycling signal amplification. One long-chain DNA (X-DNA) molecule can hybridize with two assistant DNA (F-DNA) molecules and one HIV-DNA molecule; after Exo III digests X-DNA to liberate F-DNA and HIV-DNA. F-DNA combines with P-DNA (template of DNA/AgNCs), accordingly, P-DNA is cut and the fluorescence of the system is quenched. This assay can finish in one-step without any labelling of the DNA chain or complex construction, and the strategy is sensitive with the detection limit as low as 35 pM. At the same time, the approach exhibits good selectivity even against a single base mismatch. What's more, the method is able to monitor HIV-DNA in real human serum samples; it holds great potential for early diagnosis in gene-related diseases.

Single strand DNA (ssDNA) chimeras consisting of a silver nanoclusters-nucleating sequence (NC) and an aptamer are widely employed to synthesize functional silver nanoclusters (AgNCs) for sensing purpose. Despite its simplicity, this chimeric-templated AgNCs often leads to undesirable turn-off effect, which may suffer from false positive signals caused by interference. In our effort to elucidate how the relative position of NC and aptamer affects the fluorescence behavior and sensing performance, we systematically formulated these NC and aptamer regions at different position in a DNA chimera. Using adenosine aptamer as a model, we tested the adenosine-induced optical response of each design. We also investigated the effect of linker region connecting NC and aptamer, as well as different NC sequence on the sensing performance. We concluded that locating NC sequence at 5'-end exhibited the best response, with immediate fluorescence enhancement observed over a wide linear range (1-2500 μM). Our experimental findings help to explain the emission behavior and sensing performance of chimeric conjugates of AgNCs, providing an important means to formulate a better aptasensor.

Abstract
Dysregulation of microRNAs (miRNAs) is correlated with cancer progression. In vitro detection methods using extracts from cell lysis cannot provide information about the spatial distribution of miRNAs. Due to the development of miRNA fluorescence in situ hybridization (FISH), increasing amounts of intracellular expression information are being obtained. However, miRNA FISH suffers from weak signals and complex steps and thus remains very challenging. Herein, a strategy based on DNA-templated silver nanoclusters (AgNCs/DNAs) and their G-rich fluorescence enhancement effect was developed for FISH detection of miRNAs in gastric cancer cells. The method combines hybridization and signal amplification into one step, which allows imaging of intracellular miRNAs immediately after hybridization. Most importantly, using the method based on our design, miR-101-3p, miR-16-5p and miR-19b-3p were found to be located in the nuclei of MGC803 cells with granulated shapes, indicating an unanticipated distribution pattern. In addition, before the final miRNA FISH, we performed an optimization of AgNCs/DNAs and their G-rich fluorescence enhancement effect; we found that the effect occurred at shorter wavelengths emitting green fluorescence, with weakened red fluorescence at longer wavelengths. However, the components involved in the FISH process impacted the fluorescence properties so greatly that the probes finally exhibited slightly strengthened red fluorescence signals. Our method enables facile visualization of miRNAs at the subcellular level, which may benefit the precise localization of miRNAs in single cells in the future.

Abstract
A facile, general and turn-on nucleus imaging strategy was first developed based on in situ fluorescence activation of C-rich dark silver nanoclusters by G-rich telomeres. After a simple incubation without washing, nanoclusters could selectively stain the nucleus with intense red luminescence, which was confirmed using fixed/living cells and several cell lines.

Abstract
Near-infrared silver nanoclusters, have potential applications in the field of biosensing and biological imaging. However, less stability of most DNA-AgNCs limits their application. To obtain stable near-infrared fluorescence DNA-AgNCs for biological imaging, a new kind of near-infrared fluorescent DNA-Ag nanoclusters was constructed using the C3A rich aptamer as a synthesis template, GAG as the enhancer. In particular, a new DNA-AgNCs-Trp@BSA was obtained based on the self-assembly of bovine serum albumin (BSA) and tryptophan loaded DNA-AgNCs by hydrophobic interaction. This self-assembly method can be used to stabilize DNAn-Ag (n = 1-3) nanoclusters. Hence, the near-infrared fluorescence DNA-AgNCs-Trp@BSA was applied in cellular imaging of HepG-2 cells.

Abstract
In this work, a novel fluorescent transformation phenomenon of oligonucleotide-encapsulated silver nanoclusters (AgNCs) was demonstrated, in which green-emissive AgNCs effectively transformed to red-emissive AgNCs when placed in close proximity to a special DNA fragment (denoted as convertor here). Taking advantage of a catalyzed-hairpin-assembly (CHA) amplification strategy, we rationally and compatibly engineered a simple and sensitive AgNC-based fluorescent signal amplification strategy through the ratiometric catalyzed-assembly (RCA) of green-emissive NanoCluster Beacon (NCB) with a convertor modified DNA hairpin to induce the template transformation circularly. The proposed ratiometric fluorescent biosensing platform based on RCA-amplified NCB (RCA-NCB) emits intense green fluorescence in the absence of target DNA and will undergo consecutively fluorescent signal transformation from green emission to red emission upon exposure to its target DNA. The ratiometric adaptation of the NCB to CHA circuit advances their general usability as biosensing platform with great improvements in detection sensitivity. By measuring the fluorescence intensity ratio of the red emission and green emission, the proposed RCA-NCB platform exhibits sensitive and accurate analytical performance toward Werner Syndrome-relevant gene, the proof-of-concept target in this work. A low detection limit down to the pM level was achieved, which is lower than most of the reported AgNC-based fluorescent DNA biosensors, making the proposed RCA-NCB biosensing strategy appealing in amplifying the ratiometric fluorescent signal for sensitive DNA detection. Moreover, our proposed RCA-NCB platform shows good recovery toward the target DNA in real human serum samples, illustrating their potential promise for clinical and imaging applications in the future.

Abstract
Fluorescent DNA-templated silver nanoclusters (DNA-Ag NCs) have served as excellent luminescent probes and operation units in various applications. However, the fluorescence property of DNA-Ag NCs is very sensitive to elongation or modification of the DNA template, limiting the breadth of applications. In this work, we propose a strategy for constructing a robust fluorescent DNA-Ag NCs probe module by attaching a duplex moiety to the nanocluster-bearing sequence. The fluorescence intensity of the DNA-Ag NCs can be enhanced 90-fold upon hybridization of the elongated moiety. Adenine in the linker sequence has a further enhancing effect on the fluorescence intensity, whereas thymine has a quenching effect. The transformation from a non-fluorescent species to fluorescent nanoclusters is responsible for the fluorescence enhancement with duplex formation of the elongated moiety. We hope that this design will aid future diversification of experimental designs to facilitate more applications that are currently limited by the aforementioned problems.

Abstract
Novel therapeutics is urgently needed to prevent cancer-related deaths. MicroRNAs that act as tumor suppressors have been recognized as a next-generation tumor therapy, and the restoration of tumor-suppressive microRNAs using microRNA replacements or mimics may be a less toxic, more effective strategy due to fewer off-target effects. Here, we designed the novel multifunctional oligonucleotide nanocarrier complex composed of a tumor-targeting aptamer sequence specific to mucin 1 (MUC1), poly-cytosine region for fluorescent silver nanocluster (AgNC) synthesis, and complimentary sequence for microRNA miR-34a loading. MiR-34a was employed because of its therapeutic effect of inhibiting oncogene expression and inducing apoptosis in carcinomas. By monitoring the intrinsic fluorescence of AgNC, it was clearly shown that the constructed complex (MUC1-AgNCm-miR-34a) enters MCF-7 cells. To evaluate the efficacy of this nanocarrier for microRNA delivery, we investigated the gene and protein expression levels of downstream miR-34a targets (BCL-2, CDK6, and CCND1) by quantitative PCR and western blotting, respectively, and the results indicated their effective inhibition by miR-34a. This novel multifunctional AgNC-based nanocarrier can aid in improving the efficacy of breast cancer theranostics.

Abstract
12 years after the introduction of DNA-templated silver nanoclusters (DNA-AgNCs), exciting progress has been made and yet we are still in the midst of trying to fully understand this nanomaterial. The prominent excellence of DNA-AgNCs is undoubtedly its modulatable emission property, of which how variation in DNA templates causes emission tuning remains elusive. Based on the up-to-date DNA-AgNCs, we aim to establish the correlation between the structure/sequence of DNA templates and emission behaviour of AgNCs. Herein, we systematically present a wide-range of DNA-AgNCs based on the structural complexity of the DNA templates, including single-stranded DNA (ssDNA), double-stranded DNA (dsDNA), triple-stranded DNA (tsDNA) and DNA nanostructures. For each DNA category, we discuss the emission property, quantum yield and synthesis condition of the respective AgNCs, before cross-comparing the impact of different DNA scaffolds on the properties of AgNCs. A future outlook for this area is given as a conclusion. By putting the information together, this review may shed new light on understanding DNA-AgNCs while we are expecting continuous breakthroughs in this field.

Abstract
Hypoxia-inducible factor (HIF) highly expressed in most of the cancer cells. The Mn(ii)-aptamer based nanoclusters with 3D structures would be HIF-aptamer based targeted magnetic resonance imaging agents for cancer MRI diagnosis. Herein, a new class of contrast agent Mn(ii) silver-aptamer clusters (AdpaMn@DNA-Ag-DNAG1) were constructed based on the assembly of DNA-mediated Ag nanoclusters (DNA-AgNCs) with the Mn(ii) complex (AdpaMn) and DNAG1, the recognition sequence of GLUT-1. Then, the Mn(ii) silver-aptamer clusters (AdpaMn@DNA-Ag-DNAG1) are used as the MRI agents both in vitro and in vivo. The results show that the MRI signal is clearly presented in the tumor position. Consequently, the Mn(ii) silver-aptamer clusters can be used as a new class of contrast agents for targeted MR imaging of tumors.

Abstract
Metal nanoclusters, composed of several to a few hundred metal atoms, have received worldwide attention due to their extraordinary physical and chemical characteristics. Recently, great efforts have been devoted to the exploration of the potential diagnostic and therapeutic applications of metal nanoclusters. Here we focus on the recent advances and new horizons in this area, and introduce the rising progress on the use of metal nanoclusters for biological analysis, biological imaging, therapeutic applications, DNA assembly and logic gate construction, enzyme mimic catalysis, as well as thermometers and pH meters. Furthermore, the future challenges in the construction of biofunctional metal nanoclusters for diagnostic and therapeutic applications are also discussed. We expect that the rapidly growing interest in metal nanocluster-based theranostic applications will certainly not only fuel the excitement and stimulate research in this highly active field, but also inspire broader concerns across various disciplines.

Firstly, a hairpin probe, containing target DNA recognition sequence and guanine-rich sequence, was designed to hybridize with the target DNA and form a blunt 3'-terminus DNA duplex. Then, exonuclease III (Exo III) was employed to stepwise hydrolyze the mononucleotides from formed blunt 3'-terminus DNA duplex, releasing the target DNA and guanine-rich sequence. Finally, DNA/Ag NCs fluorescent probe was introduced to hybridize with the guanine-rich sequence, leading to an enhanced fluorescence signal for detection. The proposed method could detect as low as 2.9×10(-10) mol L(-1) HIV-1 DNA and exhibited excellent selectivity against mismatched target DNA. Furthermore, the method possessed perfect recoveries in cells lysate and human serum, showing potential to be used in biological samples.
