| Abstract: | A stable Lysine monolayer was obtained on the surface of glassy carbon electrode(GCE) by means of electrochemical oxidation method.The electrostatic repulsion of the monolayer to Fe(CN)~(3-)_6 redox probe was investigated via cyclic voltammetry at different pH values and different concentrations of cations with(different) charges,respectively.The result show that the electrostatic repulsion of Lysine monolayer decreases with the increase of pH value from 1.5 to 9.7,and also decreases with the addition of Ca~(2 ) or Al~(3 ).Furthermore,the electrostatic repulsion decreases with the increase of the concentration of Ca~(2 ).Thus,it is feasible to change the charged state of carbon surface by linking Lysine to carbon surface via electrochemical oxidation that then makes the carbon surfaces have the electrostatic repulsion to negatively charged matter. |
