A new strategy for the electrochemical detection of thiols based on the disulfide cleavage combined with gold nanoparticle (AuNP) assisted signal amplification and an AuNP and graphene (GR) and ionic liquid (IL) modified carbon paste electrode (AuNP/GR/CILE). A superior detection limit of 0.4 pM toward glutathione could be achieved.
