5-amino-2-mercapto-1,3,4-thidiazole modified single-use sensors for electrochemical DNA analysis.

In this study, single-use graphite electrodes modified with 5-amino-2-mercapto-1,3,4-thidiazole (AMT) were fabricated for electrochemical monitoring of DNA. The surfaces of AMT modified pencil graphite electrodes (PGEs) were characterized by scanning electron microscopy (SEM). Electrochemical behaviors of these electrodes were investigated using differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS).
