Abstract

Preliminary results on the behavior of glassy carbon electrodes modified by cast layers of phosphatidylcholine (PC) are presented. Redox-active amphiphiles are extracted from a contacting aqueous solution into the cast lipid layer where they undergo electrochemical reactions with the underlying electrode surface. Once the lipid layer is loaded with electroactive amphiphilic material, the electrode can be transferred to pure supporting electrolyte solutions with retention of the electroactivity. In contrast, hydrophilic electroactive substrates are kept away from the electrode surface by the PC layer largely preventing the observation of electron transfer reactions with the electrode.
