N2 - Self-assembled monolayers of ω-mercapto carboxylic acids, HS(CH2)nCO2H (n = 2, 5, 10), Cn, on gold electrodes were used as a means to Induce electrochemical differentiation between a neurotransmitter, dopamine (DO), and ascorbic add (AA). Optimum differentiation is found for n = 5, and it is attributed to a compromise between a well-organized system that requires long ω-mercapto carboxylic adds and a reasonable rate of electron transfer which is observed with short ω-mercapto carboxylic acids.
