Summary: The COVID-19 epidemic caused by the SARS-CoV-2 virus has had a significant negative impact on society and global health. A sensitive, quick, and reasonably priced SARS-CoV-2 detection technology is urgently needed. Reverse transcription-loop-mediated isothermal amplification (RT-LAMP) is a promising method that amplifies a small amount of RNA to a detectable level at isothermal condition without the need for expensive equipment. In this study, a water-soluble polythiophene-based colorimetric method combined with RT-LAMP was established for fast and sensitive detection of SARS-CoV-2 RNA.

Using scanning tunneling microscopy break junction technique, we developed a direct contact method for fabrication and investigation of charge transport through single-cluster junctions of AgCu bimetallic metal clusters with different halide anchors. Experiments and calculations show that halide anchors provide efficient coupling between the cluster and the electrode, resulting in enhanced electron transport and improved transmission probability.

Summary: In this study, a highly sensitive acetylcholinesterase sensor based on 3,3',5,5'-tetramethylbenzidine(TMB) and scanning tunneling microscopy break junction (STM-BJ) was developed for the detection of organophosphorus pesticides (OPs) in environmental samples. By utilizing the enzyme inhibition kinetics of OPs and a customized spectral clustering analysis method, the sensor achieved the detection of methamidophos (MTMP) with a limit of 10 aM (10(-17) mol/L) and improved selectivity for mixed OPs. The sensor also demonstrated high reproducibility, stability, and recovery when applied to natural lake waters. This work opens up a new avenue for the application of single-molecule conductance characterizations in biochemical analysis and environmental monitoring.

Summary: The charge transport through single-molecule electronic devices can be mechanically controlled by changing the molecular geometrical configuration in situ, achieving conductance variations of more than four orders of magnitude. This is achieved by switching between constructive and destructive quantum interference pathways through designing molecules with multiple anchoring groups and shifting the electrodes within a range of about 0.6 nm. The tunable conductance range achieved using this mechanical tuning strategy is the highest reported so far.

Summary: Understanding the charge transport in sequence-controlled molecules has been a challenge due to the need for controlled synthesis and orientation. We demonstrate a general strategy of electrically driven simultaneous synthesis and crystallization to study the conductance of composition and sequence-controlled monolayers. By synthesizing monolayers uniformly between electrodes, structural disorder and conductance variations are minimized, enabling reproducible measurements on the micrometer scale. These monolayers exhibit tunable current density, on/off ratios, multistate behavior, and negative differential resistance effects.

Summary: Single-molecule electronics enable miniaturization of electronic devices, but current experiments are limited to traditional molecular structures. We developed layer-by-layer single-molecule heterojunctions using single-layer graphene electrodes, called single-molecule two-dimensional van der Waals heterojunctions (M-2D-vdWHs), which can be defined by the thickness of the molecule. By controlling the electric field, we demonstrated reversible switching behavior of the M-2D-vdWHs. These results show that stacked M-2D-vdWHs, composed of single-layer 2D materials and a single molecule, can respond to electric field stimulus, offering potential for unprecedentedly small single-molecule devices.

Summary: Using the scanning tunnelling microscope break-junction technique, different reaction states in the catalytic cycle of formate dehydrogenase were identified and conductance was used as a marker to monitor the catalytic mechanism. With multiscale simulations, it was demonstrated that NADH converts directly to NAD(+) via a hydride-transfer reaction during the catalytic cycle. This work provides insight into the mechanism of formate dehydrogenase and highlights the potential of the single-molecule technique in studying NADH/NAD(+)-dependent oxidoreductases.

Summary: Here, we present the synthesis, structure, and single-molecule conductance of three o-carborane-based molecular wires with multiple conduction channels. Through experimental and theoretical studies, we found that o-carborane-based wires have a unique three-dimensional structure that facilitates through-space transmission paths and stable molecular junction formation compared to phenyl-centered wires. The significant difference in conductance is attributed to the combination of multiple conduction channels and quantum interference. Understanding the impact of different bridging groups and anchor group substitution patterns provides valuable insights for designing multichannel molecular wires based on o-carboranes.

Summary: In this study, we report tunable arch-bridged reduced graphene oxide (rGO) nanofiltration membranes that can be modulated by applied voltage. The membranes exhibit complete rejection of organic/anionic molecules under a voltage of 5 V. By modifying the membrane with positive charges and applying voltage, the membranes show universal rejection of both cationic and anionic dyes, even in harsh organic solvents. The efficient electrical modulation is achieved through the synergistic effects of Donnan repulsion and size exclusion, enhanced by the electric field in arch-bridged rGO structures.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
