Abstract
The adsorption of uridine from 0.1M KClO4 on gold (111) and gold (210) electrodes has been examined with as main objective the detection of 2D condensed phases. The formation of an organized layer of uridine at Au(111) is supported by the occurrence of sharp spikes in the i-E and C-E curves, the influence of the surfactant concentration and the tem perature on the extent of the phase, the presence of a marked hysteres is and the associated kinetics which are controlled by a nucleation an d growth mechanism.
