A new approach was applied to modify gold electrode with a unique polymer composite for selectively detecting dopamine (DA), a neurotransmitter, in the presence of an electroactive species of ascorbic acid (AA). After self-assembly of 11-mercaptoundecanoic acid (MUA) monolayer on gold surface, polyethylene glycol (PEG) was used to perform electrochemical esterification with MUA. In general, AA is the main interference of DA detection in a biological system. The resulting composite layer showed… CONTINUE READING
