Nanomolar Level Electrochemical Detection of Glycine on a Miniaturized Modified Screen-Printed Carbon-based Electrode; A Comparison of Performance with Glassy Carbon Electrode System

In this work, we demonstrate the electrochemical (EC) sensing of glycine (GLY) on a gold–copper nanocluster on nitrogen-doped graphene quantum dot-modified (indigenously fabricated) screen-printed electrode (AuCuNC@N-GQD/SPE).
