Abstract
Metal Organic Frameworks (MOFs), a class of crystalline microporous materials have been into research limelight lately due to their commendable physio-chemical properties and easy fabrication methods. They have enormous surface area which can be a working ground for innumerable molecule adhesions and site for potential sensor matrices. Their biocompatibility makes them valuable for in vitro detection systems but a compromised conductivity requires a lot of surface engineering of these molecules for their usage in electrochemical biosensors. However, they are not just restricted to a single type of transduction system rather can also be modified to achieve feat as optical (colorimetry, luminescence) and electro-luminescent biosensors. This review emphasizes on recent advancements in the area of MOF-based biosensors with focus on various MOF synthesis methods and their general properties along with selective attention to electrochemical, optical and opto-electrochemical hybrid biosensors. It also summarizes MOF-based biosensors for monitoring free radicals, metal ions, small molecules, macromolecules and cells in a wide range of real matrices. Extensive tables have been included for understanding recent trends in the field of MOF-composite probe fabrication. The article sums up the future scope of these materials in the field of biosensors and enlightens the reader with recent trends for future research scope.

Abstract
We propose a novel washing-free electrochemiluminescence (ECL) biosensor for the simultaneous detection of two types of N6 methyladenosines-RNAs (m6A-RNAs), which are potential cancer biomarkers, on the basis of binding-induced DNA strand displacement (BINSD). The biosensor integrated a tri-double resolution strategy that combined spatial and potential resolution, hybridization and antibody recognition, and ECL luminescence and quenching. The biosensor was fabricated by separately immobilizing two ECL reagents (gold nanoparticles/g-C3N4 nanosheets and ruthenium bipyridine derivative/gold nanoparticles/Nafion) and the capture DNA probe on the two sections of glassy carbon electrode. As a proof of concept, m6A-Let-7a-5p and m6A-miR-17-5p were chosen as model analytes, while m6A antibody-DNA3/ferrocene-DNA4/ferrocene-DNA5 was designed as an m6A-binding probe and DNA6/DNA7 was designed as a hybridization probe with DNA3 to release the quenching probes ferrocene-DNA4/ferrocene-DNA5. The recognition process led to the quenching of the ECL signals from both probes via BINSD. The proposed biosensor has the advantage of being washing-free. The ECL methods using the fabricated ECL biosensor with the designed probes exhibited a low detection limit of 0.03 pM for two m6A-RNAs and high selectivity. This work reveals that this strategy is promising for developing an ECL method for the simultaneous detection of two m6A-RNAs. The proposed strategy could be expanded to develop the analytical methods for the simultaneous detection of other RNA modifications by changing the antibody and hybridization probe sequences.

Recent strategies for electrochemical sensing detection of miRNAs in lung cancer. Anal Biochem 2023; 661:114986. [PMID: 36384188 DOI: 10.1016/j.ab.2022.114986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Revised: 11/10/2022] [Accepted: 11/11/2022] [Indexed: 11/15/2022]
Abstract
MicroRNAs (miRNAs) associated with lung cancer are diversifying. MiR-21, Let-7, and miR-141 are common diagnostic targets. Some new lung cancer miRNAs, such as miR-25, miR-145, and miR-126, have received increasing attention. Although various techniques are available for the analysis of lung cancer miRNAs, electrochemistry has been recognized for its high sensitivity, low cost, and rapid response. However, how to realize the signal amplification is one of the most important contents in the design of electrochemical biosensors. Herein, we mainly introduce the amplification strategy based on enzyme-free amplification and signal conversion, including non-linear HCR, catalytic hairpin assembly (CHA), electrochemiluminescence (ECL), and Faraday cage. Furthermore, new progress has emerged in the fields of nanomaterials, low oxidation potential, and simultaneous detection of multiple targets. Finally, we summarize some new challenges that electrochemical techniques may encounter in the future, such as improving single-base discrimination ability, shortening electrochemical detection time, and providing real body fluid samples assay.

Abstract
The hybridization chain reaction (HCR) is widely used for biosensing. However, HCR does not provide the required sensitivity. In this study, we reported a method to improve the sensitivity of HCR by dampening the cascade amplification. First, we designed a biosensor based on HCR, and an initiator DNA was used to trigger the cascade amplification. Optimization of the reaction was then performed, and the results showed that the limit of detection (LOD) for the initiator DNA was about 2.5 nM. Second, we designed a series of inhibitory DNAs to dampen the HCR cascade amplification, and DNA dampeners (50 nM) were applied in the presence of the DNA initiator (50 nM). One of the DNA dampeners (D5) showed the best inhibitory efficiency of greater than 80%. This was further applied at concentrations ranging from 0 nM to 10 nM to prohibit the HCR amplification caused by a 2.5 nM initiator DNA (the limit of detection for this initiator DNA). The results showed that 0.156 nM of D5 could significantly inhibit the signal amplification (p<0.05). Additionally, the limit of detection for the dampener D5 was 16 times lower than that for the initiator DNA. Based on this detection method, we achieved a detection limit as low as 0.625 nM for HCV-RNAs. In summary, we developed a novel method with improved sensitivity to detect the target designed to prohibit the HCR cascade. Overall, this method could be used to qualitatively detect the presence of single-stranded DNA/RNA.
