Arce etal. [140, 141] have studied the dynamics of 1-dodecanethiol and bu-tanethiol SAMs on Au(lll), applying ex situ and in situ STM. The potential of zero charge for the thiol-modified Au(lll) electrode was determined for self-assembled monolayers of octade-canethiolate (—0.52 V), undecanethiolate (—0.49 V), propanethiolate (—0.3 V), and H, //,2//,2 //-perfluorodecanethiolate (1.04 V) ]142]. The potentials (expressed versus Ag]AgCl]saturated KCl electrode) were determined from the measurements of the contact angle for a droplet of 0.1 M NaCl04 aqueous solution. 

Cooke and coworkers have reported preparation of flavin-modified electrodes using a similar electropolymerization procedure.34 They have also studied electrodes coated with self-assembled monolayers (SAMs) formed from both flavin39 and phenanthrenequinone disulfides.59 The monolayers are stable in CH2C12 solution, and, as with the electrodes formed from 30, show redox-dependent binding behavior similar to that seen in solution. Interestingly, the phenanthrenequinone SAM... 

Finally, Majda has investigated a novel inorganic membrane-modified electrode [32]. The membrane used was a microporous alumina prepared by anodizing metallic aluminum in an acidic electrolyte [33]. Majda et al. lined the pores of these membranes with polymers and self-assembled monolayers and studied electron and ion transfer down the modified pore walls to a substrate electrode surface [32]. Martin and his coworkers have used the pores in such membranes as templates to prepare nanoscopic metal, polymer, and semiconductor particles [34],...

Scheme 13.1. Steps in the fabrication of the peptide-modified electrode. A clean gold electrode is modified with a self-assembled monolayer of MPA followed by activation of the carboxyl groups with EDC/NHS. Coupling of the N-terminus of the peptide results in the formation of the peptide-modified electrode.
