Electrochemical polymerized 5-amino-2-mercapto-1,3,4-thiadiazole modified single use sensors for detection of quercetin.

In this study, electrochemical polymerized 5-amino-2-mercapto-1,3,4-thiadiazole (poly-AMT)-modified single-use graphite electrodes were fabricated for electrochemical monitoring of bisflavonoid, quercetin. The surfaces of p-AMT modified pencil graphite electrodes (PGEs) were firstly characterized by scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) analysis. The conditions for electrochemical polymerization by using cyclic voltammetry (CV), such as scan rate and different potential cycles were optimized.
