Abstract
Self-assembled monolayers of ω-mercapto carboxylic acids, HS(CH 2 ) n CO 2 H (n=2, 5, 10), C n , on gold electrodes were used as a means to induce electrochemical differentiation between a neurotransmitter, dopamine (DO), and ascorbic acid (AA). Optimum differentiation is found for n=5, and it is attributed a compromise between as well-organized system that requires long ω-mercapto carboxylic acids and a reasonable rate of electron transfer which is observed with short ω-mercapto carboxylic acids
