【Abstract】 Electron transfer process between dopamine covalently modified on thioctic acid self-assembled monolayers has been investigated.The electrochemical oxidation of dopamine on self-assembled monolayers modified electrodes is a two-step single electron transfer process,in which the intermediate of semiquinone and hydrogen proton are concerned.
