Abstract
MicroRNA (miRNA) has emerged as a promising biomarker for disease diagnosis and a potential therapeutic targets for drug development. The detection of miRNA can serve as a noninvasive tool in diseases diagnosis and predicting diseases prognosis. CRISPR/Cas12a system has great potential in nucleic acid detection due to its high sensitivity and specificity, which has been developed to be a versatile tool for nucleic acid-based detection of targets in various fields. However, conversion from RNA to DNA with or without amplification operation is necessary for miRNA detection based on CRISPR/Cas12a system, because dsDNA containing PAM sequence or ssDNA is traditionally considered as the activator of Cas12a. Until recently, direct detection of miRNA by CRISPR/Cas12a system has been reported. In this review, we provide an overview of the evolution of biosensors based on CRISPR/Cas12a for miRNA detection from indirect to direct, which would be beneficial to the development of CRISPR/Cas12a-based sensors with better performance for direct detection of miRNA.

Abstract
The ligase chain reaction (LCR), as a classic nucleic acid amplification technique, is popular in the detection of DNA and RNA due to its simplicity, powerfulness, and high specificity. However, homogeneous and ultrasensitive LCR detection is still quite challenging. Herein, we integrate the LCR with a CRISPR-Cas12a system to greatly promote the application of the LCR in a homogeneous fashion. By employing microRNA as the model target, we design LCR probes with specific protospacer adjacent motif sequences and the guide RNA. Then, the LCR is initiated by target microRNA, and the LCR products specifically bind to the guide RNA to activate the Cas12a system, triggering secondary signal amplification to achieve ultrasensitive detection of microRNA without separation steps. Moreover, by virtue of a cationic conjugated polymer, microRNA can not only be visually detected by naked eyes but also be accurately quantified based on RGB ratio analysis of images with no need of sophisticated instruments. The method can quantify microRNA up to 4 orders of magnitude, and the determination limit is 0.4 aM, which is better than those of other reported studies using CRISPR-Cas12a and can be compared with that of the reverse-transcription polymerase chain reaction. This study demonstrates that the CRISPR-Cas12a system can greatly expand the application of the LCR for the homogeneous, ultrasensitive, and visual detection of microRNA, showing great potential in efficient nucleic acid detection and in vitro diagnosis.

Abstract
Infectious diseases caused by viruses such as SARS-CoV-2 and HPV have greatly endangered human health. The nucleic acid detection is essential for the early diagnosis of diseases. Here, we propose a method called PLCR (PfAgo coupled with modified Ligase Chain Reaction for nucleic acid detection) which utilizes PfAgo to only use DNA guides longer than 14-mer to specifically cleave DNA and LCR to precisely distinguish single-base mismatch. PLCR can detect DNA or RNA without PCR at attomolar sensitivities, distinguish single base mutation between the genome of wild type SARS-CoV-2 and its mutant spike D614G, effectively distinguish the novel coronavirus from other coronaviruses and finally achieve multiplexed detection in 70 min. Additionally, LCR products can be directly used as DNA guides without additional input guides to simplify primer design. With desirable sensitivity, specificity and simplicity, the method can be extended for detecting other pathogenic microorganisms.

Biocomputing label-free security system based on homogenous ligation chain reaction-induced dramatic change in melting temperature for screening single nucleotide polymorphisms.

Abstract
The development of smart platform with accurate, inexpensive and reliable detection of single-nucleotide polymorphisms (SNPs) has long been concerned in the fields of medical diagnosis and basic research. Here, we present a ligation chain reaction (LCR)-based sensing system for the cost-effective screening of SNPs by simply conducting DNA melting analysis. No chemical modification is required and the signaling operation is accomplished in homogeneous solution, circumventing the complex modification process and possibly compromised enzymatic activity associated with heterogeneous materials, such as quantum dot (QD) and gold nanoparticle (GNP). Due to the enzymatic catalysis and high fidelity of ligase, the system is capable of executing signal amplification, providing a high sensitivity and selectivity. KRAS gene is easily recognized and the site-specific mutation of guanine (G) to adenine (A), thymine (T) or cytosine (C) is accurately screened. Moreover, the excellent reliability was demonstrated by blind test and recovery test. LCR-based signaling mechanism was further used to develop the biocomputing security system, and two logic gates consisting of four single-stranded DNAs (ssDNAs) offer a double insurance to protect the information against illegal invasion, guaranteeing the reliability of output information. Once in the absence of one essential factor, the security system was always locked regardless of target key, serving as a novel strategy to ensure the safety of output information at molecular level. As a proof-of-concept scheme, this contribution introduces new insight into the development of DNA security systems and the exploitation of powerful signal transduction strategy suitable for rapid and convenient disease diagnosis.

Abstract
Despite huge successes achieved by strand displacement amplification (SDA) and gold nanoparticles (AuNPs) in biomolecules sensing, the strategy of combination of SDA and AuNPs-based dynamic light scattering (DLS) for a biomolecule sensing is unexplored. Here we developed a non-invasive, SDA-based DLS method for the diagnosis of bladder cancer by detecting telomerase activity in human urine. In the presence of telomerase, the telomerase substrate (TS) primer was elongated with repeating sequences of (TTAGGG)n, and the resulting product triggers SDA between the hairpin deoxyribonucleic acid (DNA) and the Primer. The SDA product can be recognized by the oligonucleotide-modified AuNPs probes, resulting in DLS measurable AuNPs aggregation. The assay displayed a detection limit of 3 MCF-7 cells with a signal-to-noise ratio of 3 in a dynamic range of 5-1000 cells. The method was simple, reliable and has been successfully applied in the detection of telomerase in urine with good accuracy, selectivity and reproducibility. Moreover, only urine samples from bladder cancer patients induced a significant change in the average hydrodynamic diameter, indicating practical applicability of the method for the non-invasive diagnosis of bladder cancer.

Abstract
The authors describe a novel assay for the detection of methylated DNA site. Rolling circle amplification and CdSe/ZnS quantum dots with high fluorescence efficiency are applied in this method. The CdSe/ZnS quantum dots act as electron donors, and hemin and oxygen (derived from hydrogen peroxide act as acceptors in photoinduced electron transfer.

Abstract
In vitro biosensors have been an integral component for early diagnosis of cancer in the clinic. Among them, no-wash biosensors, which only depend on the simple mixing of the signal generating probes and the sample solution without additional washing and separation steps, have been found to be particularly attractive. The outstanding advantages of facile, convenient, and rapid response of no-wash biosensors are especially suitable for point-of-care testing (POCT). One fast-growing field of no-wash biosensor design involves the usage of nanomaterials as signal amplification carriers or direct signal generating elements. The analytical capacity of no-wash biosensors with respect to sensitivity or limit of detection, specificity, stability, and multiplexing detection capacity is largely improved because of their large surface area, excellent optical, electrical, catalytic, and magnetic properties. This review provides a comprehensive overview of various nanomaterial-enhanced no-wash biosensing technologies and focuses on the analysis of the underlying mechanism of these technologies applied for the early detection of cancer biomarkers ranging from small molecules to proteins, and even whole cancerous cells. Representative examples are selected to demonstrate the proof-of-concept with promising applications for in vitro diagnostics of cancer. Finally, a brief discussion of common unresolved issues and a perspective outlook on the field are provided.

Abstract
Genetic variants have been reported to cause several genetic diseases. Various genotyping assays have been developed for diagnostic and screening purposes but with certain limitations in sensitivity, specificity, cost effectiveness and/or time savings. Since the discovery of ligase chain reaction (LCR) in the late nineties, it became one of the most favored platforms for detecting these variants and also for genotyping low abundant contaminants. Recent and powerful modifications with the integration of various detection strategies such as electrochemical and magnetic biosensors, nanoparticles (NPs), quantum dots, quartz crystal and leaky surface acoustic surface biosensors, DNAzyme, rolling circle amplification (RCA), strand displacement amplification (SDA), surface enhanced raman scattering (SERS), chemiluminescence and fluorescence resonance energy transfer have been introduced to both LCR and ligation based amplifications to enable high-throughput and inexpensive multiplex genotyping with improved robustness, simplicity, sensitivity and specificity. In this article, classical and up to date modifications in LCR and ligation based amplifications are critically evaluated and compared with emphasis on points of strength and weakness, sensitivity, cost, running time, equipment needed, applications and multiplexing potential. Versatile genotyping applications such as genetic diseases detection, bacterial and viral pathogens detection are also detailed. Ligation based gold NPs biosensor, ligation based RCA and ligation mediated SDA assays enhanced detection limit tremendously with a discrimination power approaching 1.5aM, 2aM and 0.1fM respectively. MLPA (multiplexed ligation dependent probe amplification) and SNPlex assays have been commercialized for multiplex detection of at least 48 SNPs at a time. MOL-PCR (multiplex oligonucleotide ligation) has high-throughput capability with multiplex detection of 50 SNPs/well in a 96 well plate. Ligase detection reaction (LDR) is one of the most widely used LCR versions that have been successfully integrated with several detection strategies with improved sensitivity down to 0.4fM.

Abstract
Gold nanoparticles have proven to be promising for decentralized nucleic acid testing by virtue of their simple visual readout and absorbance-based quantification. A major challenge toward their practical application is to achieve ultrasensitive detection without compromising simplicity. The conventional strategy of thermocycling amplification is unfavorable (because of both instrumentation and preparation of thermostable oligonucleotide-modified gold nanoparticle probes). Herein, on the basis of a previously unreported co-precipitation phenomenon between thiolated poly(ethylene glycol)/11-mercaptoundecanoic acid co-modified gold nanoparticles and magnesium pyrophosphate crystals (an isothermal DNA amplification reaction byproduct), a new ultrasensitive and simple DNA assay platform is developed. The binding mechanism underlying the co-precipitation phenomenon is found to be caused by the complexation of carboxyl and pyrophosphate with free magnesium ions. Remarkably, poly(ethylene glycol) does not hinder the binding and effectively stabilizes gold nanoparticles against magnesium ion-induced aggregation (without pyrophosphate). In fact, a similar phenomenon is observed in other poly(ethylene glycol)- and carboxyl-containing nanomaterials. When the gold nanoparticle probe is incorporated into a loop-mediated isothermal amplification reaction, it remains as a red dispersion for a negative sample (in the absence of a target DNA sequence) but appears as a red precipitate for a positive sample (in the presence of a target). This results in a first-of-its-kind gold nanoparticle-based DNA assay platform with isothermal amplification and real-time monitoring capabilities.

Visualized detection of single-base difference in multiplexed loop-mediated isothermal amplification amplicons by invasive reaction coupled with oligonucleotide probe-modified gold nanoparticles. Biosens Bioelectron 2016; 90:388-393. [PMID: 27960145 DOI: 10.1016/j.bios.2016.12.015] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2016] [Revised: 11/20/2016] [Accepted: 12/07/2016] [Indexed: 11/19/2022]
Abstract
Loop-mediated isothermal amplification (LAMP) is a well-developed DNA amplification method with an ultra-high sensitivity, but it is difficult to recognize a single-base difference (like genotyping) in target-specific amplicons by conventional detection ways, such as the intercalation of dyes into dsDNA amplicons or the increase of solution turbidity along with the polymerization process. To allow genotyping based on LAMP suitable for POCT (point-of-care testing) or on-site testing, here we proposed a highly specific and cost-effective method for detecting a single-base difference in LAMP amplicons. The method includes three key steps, sequence amplifier to amplify multiple fragments containing the single nucleotide polymorphisms (SNPs) of interest, allele identifier to recognize a targeted base in the amplicons by invasive reaction, and signal generator to yield signals by hybridization-induced assembly of oligonucleotide probe-modified gold nanoparticles. Because the allele identifier is sensitive to one base difference, it is possible to use multiplexed LAMP (mLAMP) to generate amplicon mixtures for multiple SNP typing. Genotyping of 3 different SNPs (CYP2C19*2, CYP2C19*3 and MDR1-C3435T) for guiding the dosage of clopidogrel is successfully carried out in a 3-plex LAMP on real clinical samples. As our method relies on the naked-eye detection and constant-temperature reaction, no expensive instrument is required for both target amplification and sequence identification, thus much suitable for inexpensive gene-guided personalized medicine in source-limited regions.

Abstract
When citrate ligands-capped gold nanoparticles are mixed with blood sera, a protein corona is formed on the nanoparticle surface due to the adsorption of various proteins in the blood to the nanoparticles. Using a two-step gold nanoparticle-enabled dynamic light scattering assay, we discovered that the amount of human immunoglobulin G (IgG) in the gold nanoparticle protein corona is increased in prostate cancer patients compared to noncancer controls. Two pilot studies conducted on blood serum samples collected at Florida Hospital and obtained from Prostate Cancer Biorespository Network (PCBN) revealed that the test has a 90-95% specificity and 50% sensitivity in detecting early stage prostate cancer, representing a significant improvement over the current PSA test. The increased amount of human IgG found in the protein corona is believed to be associated with the autoantibodies produced in cancer patients as part of the immunodefense against tumor. Proteomic analysis of the nanoparticle protein corona revealed molecular profile differences between cancer and noncancer serum samples. Autoantibodies and natural antibodies produced in cancer patients in response to tumorigenesis have been found and detected in the blood of many cancer types. The test may be applicable for early detection and risk assessment of a broad spectrum of cancer. This new blood test is simple, low cost, requires only a few drops of blood sample, and the results are obtained within minutes. The test is well suited for screening purpose. More extensive studies are being conducted to further evaluate and validate the clinical potential of the new test.

Abstract
An ultrasensitive colorimetric DNA and RNA assay using a combination of enzyme-free click chemical ligation chain reaction (CCLCR) on dispersed gold nanoparticles (GNPs) and a magnetic separation process has been developed. The click chemical ligation between an azide-containing probe DNA-modified GNP and a dibenzocyclooctyne-containing probe biotinyl DNA occurred through hybridization with target DNA (RNA) to form the biotinyl-ligated GNPs (ligated products). Eventually, both the biotinyl-ligated GNPs and target DNA (RNA) were amplified exponentially using thermal cycling. After separation of the biotinyl-ligated GNPs using streptavidin-modified magnetic beads, the change in intensity of the surface plasmon band at 525 nm in the supernatants was observed by UV/vis measurement and was also evident visually. The CCLCR assay provides ultrasensitive detection (50 zM: several copies) of target DNA that is comparable to PCR-based approaches. Note that target RNA could also be detected with similar sensitivity without the need for reverse transcription to the corresponding cDNA. The amplification efficiency of the CCLCR assay was as high as 82% due to the pseudohomogeneous reaction behavior of CCLCR on dispersed GNPs. In addition, the CCLCR assay was able to discriminate differences in single-base mismatches and to specifically detect target DNA and target RNA from the cell lysate.

Abstract
A monoclonal antibody for microcystin-leucine-arginine (MC-LR) was produced by cell fusion. The immunogen was synthesized in two steps. First, ovalbumin/ bovine serum albumin was conjugated with 6-acetylthiohexanoic acid using a carbodiimide EDC (1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride)/ NHS (N-hydroxysulfosuccinimide) reaction. After dialysis, the protein was reacted with MC-LR based on a free radical reaction under basic solution conditions. The protein conjugate was used for immunization based on low volume. The antibodies were identified by indirect competitive (ic)ELISA and were subjected to tap water and lake water analysis. The concentration causing 50% inhibition of binding of MC-LR (IC50) by the competitive indirect ELISA was 0.27 ng/mL. Cross-reactivity to the MC-RR, MC-YR and MC-WR was good. The tap water and lake water matrices had no effect on the detection limit. The analytical recovery of MC-LR in the water samples in the icELISA was 94%-110%. Based on this antibody, an immunochromatographic biosensor was developed with a cut-off value of 1 ng/mL, which could satisfy the requirement of the World Health Organization for MC-LR detection in drinking water. This biosensor could be therefore be used as a fast screening tool in the field detection of MC-LR.
