Summary: In this study, a novel hedgehog-shaped bismuth sulfide nanostructure was explored for the first time as an electrode material for biosensing, leading to the development of a sensitive electrochemical glucose biosensor. The hedgehog-shaped nanostructure of Bi2S3 with its large specific surface area and enhanced direct-electron-transfer action of enzymes resulted in a biosensor with a wide linear range, low detection limit, high selectivity, good repeatability, and stability. The biosensor shows better assay performance compared to conventional glucose biosensors, making it suitable for measuring blood glucose in real serum samples.

Summary: In this study, a simple method for colloidal growth of TiO2 in nanoporous gold (NPG) was demonstrated. The coverage of gold ligaments with TiO2 was achieved and the characteristics of surfactants were found to influence the properties of TiO2 growth. The colloidal TiO2 growth enhanced the efficiency of electrochemical H-2 evolution and increased the exchange current. This approach is of significance for controlling surface coverage in material fabrication.

Summary: This work demonstrates a simple bioinspired route of synthesizing template-free 1D Bi2S3 nanorods, Bi2S3-NRs(bio), using Sechium edule fruit. The morphology of nanorods was controlled via capping of ascorbic acid (AA), a major bio-analyte. The average length and diameter were reduced, and the formation of Bi2O3 could be prevented by AA capping. The modified Bi2S3-NRs(bio)/Toray carbon paper (TCP) electrode exhibited selective HCOO- formation with higher faradaic efficiency (FE) compared to the Bi2S3-NRs(control)/TCP electrode. The enhanced and selective HCOO- formation is attributed to the compositional and morphological attributes of Bi2S3-NRs(bio).

Summary: The scientific community has been searching for efficient carbon dioxide (CO2) valorization technologies due to increased scrutiny over carbon emissions. Among them, electrocatalytic CO2 reduction (eCO2R) using Copper (Cu)-derived catalytic materials powered by renewable electricity has gained attention. However, striking a balance between overall activity and desired C2+ product selectivity has been challenging. In this work, we demonstrate that atacamite (Cu2(OH)3Cl) supported over inexpensive precipitated calcium carbonate exhibits superior performance in selectively producing C2+ products (-1 V vs RHE with 32% faradaic efficiency) and has a durable lifetime. Various characterization techniques were used to determine the structure-performance correlation.

Summary: The presence of pesticide and mycotoxin residues in food poses a potential risk to human health. Traditional detection methods, such as HPLC, lack sensitivity and convenience. In recent years, nanotechnology has facilitated the development of electrochemical biosensors based on nanomaterials, which offer rapid and accurate detection of trace amounts of pesticides and mycotoxins. This review examines English articles on electrochemical biosensors published between 2011 and 2022, focusing on various nanomaterials, including noble metals, magnetic nanoparticles, metal-organic frameworks, carbon nanotubes, graphene, and its derivatives. The roles of these nanomaterials in the detection process are discussed, along with the targeted pesticides and mycotoxins. Despite significant progress, challenges still need to be addressed for further advancements in electrochemical nano-biosensors.
