Název v původním jazyce

Two-dimensional condensation of nucleic acid components at mercury film and gold electrodes

Popis výsledku v původním jazyce

The kinetics of structural changes in cytidine and deoxycytidine adlayers on the mercury film electrodes were investigated by means of current and capacitance transients using the potential step technique. By means of j-t transients we studied the processes taking place at the beginning of the growth or dissolution of physical condensed and highly ordered adlayers. On the other site the C-t transients revealed changes taking place within physical condensed cytidine adlayers at longer times. The kineticsof the interfacial rearrangements were better observed with the pyrolytic carbon than with glassy carbon electrodes. The experimental j-t and C-t curves were analysed by comparison with several models based on the nucleation and growth in combination with a parallel Lanqmuir-type adsorption/desorption process. Adsorption of cytidine on Au(111) from 0.1 M KClO4 electrolyte solution is characterized by formation of various films delimited by 2-D phase transitions.
