Monolayer films of thiols with different terminal groups (CH 3, COOH and NH 2) were prepared on gold electrodes using a self-assembling procedure. Cyclic voltammetry was used to investigate the electron-transfer reaction of potassium ferricyanide at the thiol modified gold electrode in the presen...
