Abstract

Construction and characterization of microfabricated recessed disk microelectrodes (RDMs) of 14 and 55 μm diameter are reported. The work reported here makes several new contributions to the current literature on microfabricated RDMs. Hybrid blamers were constructed by fusion of vesicles of dimyristoylphosphatidyl choline (DMPC), which forms the top layer, with ethanol-rinsed SAMs of hexadecanethiol on gold, which form the bottom layer. Gramicidin A was included in the modifying solutions to incorporate it into hybrid blamers.
