Summary: Cyclic voltammetry and single-entity electrochemistry were used to evaluate the electrocatalysis of the VO2+/VO2+ redox couple by bamboo-like multiwalled carbon nanotubes. It was found that individual nanotubes accelerated the oxidation reaction but retarded the reduction reaction. When an ensemble of nanotubes was drop-casted onto a glassy carbon electrode, an electrochemically nearly reversible response was observed and explained by changes in mass transport regime.

Summary: As a crucial parameter in biochemical analysis, the pH value plays an essential role in cell function, food preservation and production, as well as soil and water sources. Therefore, it is increasingly important to explore pH detection methods. This paper introduces a pH-responsive SERS probe using a cyano Raman tag, which can detect pH values based on the displacement of the cyano Raman peak. The cyano Raman tag exhibits excellent sensitivity within the pH range of 3.0-9.0, with a limit of detection of pH 0.33, and shows anti-interference performance and stability (the relative standard deviation is calculated to be 6.68%, n = 5). These results suggest that this pH SERS probe with the Raman cyano tag could open up new research directions in biological detection, bioimaging, and environmental detection.

Summary: Surface-enhanced Raman scattering (SERS) is a fascinating phenomenon that enhances the Raman signals of molecules by creating hot spots. In this study, a high-performance Ag/ZIF-8 SERS substrate is fabricated using a simple two-step method. Plasmonic nanogaps are created between the Ag nanocap and the Ag layer on the substrate, resulting in greatly enhanced electromagnetic (EM) field and preconcentration effect. The measurement results show high SERS enhancement factor, low detectable concentration, and low relative standard deviation, suggesting the potential of this substrate for molecular detection.

Summary: This study presents a novel single-particle detection method for quantifying Hg2+ using dark-field optical microscopy (DFM)-correlated Raman spectroscopy. The method utilizes a tetrahedral DNA-directed core-satellite nanostructure as a surface-enhanced Raman scattering (SERS) probe, and achieves Raman signal enhancement by reducing the interparticle distance upon the specific recognition of Hg2+. The method demonstrates high sensitivity and selectivity, and has been successfully applied to detect Hg2+ in practical tap water and lake water samples.

Summary: In this study, N-methyl mesoporphyrin IX (NMM) was utilized as a voltammetric probe for the electrochemical detection of G4s. The detection of NMM was achieved by cyclic voltammetry on a hanging mercury drop electrode (HMDE) with a limit of detection (LOD) of 40 nM. The reduction signal of NMM was found to be significantly higher when G4 oligodeoxynucleotides (G4 ODNs) were present compared to single- or double-stranded ODNs or unfolded ODNs capable of forming G4s. Gradual transition from unstructured single strand to G4, induced by increasing concentrations of the G4 stabilizing K+ ions, was detected for the first time using electrochemical methods. Circular dichroism spectroscopy provided support for the obtained results. This work expands on the utilization of electrochemical probes for DNA secondary structure recognition and offers a proof of principle for the development of novel electroanalytical methods for nucleic acid structure studies.
