A novel electrochemical sensor for rapid detection of sulfathiazole by integrating [(4,4'-bipy/PMoCo)] modified electrode.

In this study, we focused on the successful construction of [(4,4'-bipy/PMoCo)] modified electrodes using the layer-by-layer assembly method for the sensitive detection of sulfathiazole (ST). The redox reaction between ST and the metal ions in the modified layer leads to the transfer of electrons, resulting in the generation of the electrical signal. The introduction of 4,4'-bipyridine (4,4'-bipy) enhanced the molecular recognition of ST by the modified electrode.
