“…Reflectivity change was enhanced by increasing the dopamine concentration but reached a limiting value at about 1 x 10-4M. The adsorption of dopamine thus appears to occur on the gold electrode surface, since a decrease in reflectivity was often found to result from adsorption of organic compounds (10), and could be explained by the following linear approximation equation (11) (AR/Ro) 9 1 -8Trdns cos qb e"ad (ns 2 -E'M) + e"~i (iliad --ns 2)…”

The surface behavior of neurotransmitters, their agonists and antagonists on a gold electrode/phosphate buffer solution was studied by specular reflection measurement. There was adsorption of the following neurotransmitters: ~/-aminobutyric acid, glycine, ~-alanine, dopamine, norepinephrine, epinephrine, acetylcholine, glutamic acid, and aspartic acid in the potential range of -200 to 200 mV vs. the point of zero charge. The potential profiles of adsorption between inhibitory and excitatory neurotransmitters were noted to differ. Their antagonists were adsorbed onto the electrode more strongly than the neurotransmitters. The adsorption potential profile provides clarification of the electrostatic interactions between the receptor site and neurotransmitter or related drugs.
