Summary: This study prepared a TiO2-doped 3DGR nanocomposite via one-step hydrothermal synthesis method, and investigated the influence of acid-base property and sweep speed on its electrochemical behavior. The Nafion/Mb/TiO2@3DGR/CILE biosensor exhibited good electrocatalytic activity for trichloroacetic acid, NaNO2, and H2O2, with wider range of linearity and lower limit of detection. The biosensor is significant for future research and development of electrochemical biosensors.

Summary: In this study, a novel DNA sensor based on Carbon/La3+/CuO (C/La3+/CuO) nanocomposites was developed for the determination of isoniazid (INZ). The modified electrode showed excellent conductivity and improved sensor sensitivity. This label-free sensor could selectively and sensitively detect INZ with a wide linear range and low detection limit. The biosensor was successfully applied to detect INZ in real samples, demonstrating its excellent analytical potential. Electrochemical, spectroscopic, and docking methods confirmed the effective interaction between INZ and ds-DNA.

Summary: In this study, a rapid targeted identification and analysis method of antibiotic resistance genes (ARGs) was established using an electrochemical sensor modified with a sulfhydryl single-stranded DNA probe. The sensor showed good detection performance for ARGs encoding beta-lactam hydrolase, with a linear detection range of 6.3-900.0 ng/mL and high specificity for different types of DNA mismatches. The accurate identification and analysis of ARGs could still be maintained after 30 days of storage at 4 degrees C.

Summary: In this work, a unique MXene/TiO2-graphene aerogel composite with a 3D hierarchical porous framework was developed, assisted by ferric ions. The composite exhibited a large specific surface area and amorphous TiO2 on the surface of MXene nanosheets. The amorphous TiO2 contributed to pseudocapacitance through reversible redox reactions with lithium ions, and the variable valence states of ferric cations also provided pseudocapacitance. The study also formulated a trinary ionic liquid-based electrolyte with a wide electrochemical stability potential window to match the new material.

Summary: In this study, imidazolyl dinitrile amine salt was used as an intercalation agent and modifier to achieve the exfoliation and modification of graphite into graphene. Surface/interface techniques were employed to ensure successful preparation and high-density modification of the graphene. The modified graphene showed improved tribological behaviors and stability in polyethylene glycol 200, attributed to its thinner size and protective layer on mating interfaces.
