Abstract:

In this research work, we discuss the fabrication of an electrochemical sensor that can successfully detect 10-3 M concentration of sulphur dioxide. Electrochemical analyses were carried out using glassy carbon electrode modified with the protein – bovine serum albumin. The studies were carried out experimentally and theoretically. The theoretical studies were by molecular docking of bovine serum albumin with sulphur dioxide and experimentally, cyclic voltammetry was performed for different scan rates and concentrations of sulphur dioxide. The results obtained prove that bovine serum albumin has appreciable interaction with sulphur dioxide and hence can be used as a basis for the detection of the same.
