Detection of hydrogen peroxide involving bismuth nanowires via template-free electrochemical synthesis using deep eutectic solvents

Abstract Nanomaterials with different morphologies have been important in the development of electrochemical sensors with applications in the biomedical field. In the last decade, there has been increasing interest in Bi-based nanostructures for sensing applications where green strategies are preferred. The template-free synthesis of Bi nanowires (BiNWs) involving deep eutectic solvents (DESs) as electrolytes has enabled the fabrication of a sensing platform with electrocatalytic activity towards hydrogen peroxide. The target molecule plays an important part in the development of cancers and its detection could shed light on the dynamics related to cellular metabolism, with applications in medical research. The BiNW-based platform is shown to detect the molecule of interest in the presence of common interfering agents and offers avenues for further development.
