Abstract
Herein is disclosed a method for detecting a material comprising a thiol group (e.g. homocysteine, cysteine, glutathione) in a sample, the method comprising: •providing an electrode comprising a carbon material; •contacting said electrode with said sample in the presence of catechol or more generally a precursor of ortho-quinone; •performing cyclic or square wave voltammetry to convert catechol to ortho-quinone and wherein said ortho-quinone reacts with the material comprising a thiol group to form an electrochemical reaction product.
