Determination of glutathione in vivo by microdialysis using liquid chromatography with a cobalt hexacyanoferrate chemically modified electrode

A new chemically modified electrode (CME) was found to be comparable to a glassy carbon electrode in terms of the eletrocatalytic effect of Cobalt Hexacyanoferrate (CoHCF) towards thiolcompounds (glutathione (GSH), cysteine (Cys), N-acetylcysteine (NAC)). Polynuclear CoHCF thin films are electrodeposited on a glassy carbon electrode by potential cycling between 1.2 V and −0.2 V versus Ag/AgCl in a fresh modification solution containing 0.5...
