Abstract

In this communication we report a proof of concept study of the use of cyclic voltammetry with a polyeugenol‐modified glassy carbon (GC) electrode to selectively detect L‐cysteine in the presence of both dl‐homocysteine and glutathione in perchloric acid. The formation of a polyeugenol‐modified gold electrode is also reported for the first time.
