Selective electrochemical determination of cysteine with a cyclotricatechylene modified carbon electrode.

Abstract:

We report the selective electrochemical detection of cysteine in the presence of homocysteine and glutathione with the use of an electrode modified with cyclotricatechylene (CTC). A carbon electrode was first modified with cyclotriveratrylene (CTV) and then electrochemically converted into CTC. Using cyclic voltammetry, the redox activity of CTC was investigated along with its electrochemical response to cysteine and the closely related compounds, glutathione and homocysteine which are common...
