摘要：

Self-assembled monolayers of omega-mercapto carboxylic acids, HS(CH2)nCO2H (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 to a compromise between a well-organized system that requires long omega-mercapto carboxylic acids and a reasonable rate of electron transfer which is observed with short omega-mercapto carboxylic acids.
