Characterization of polymer stabilized silver nanoparticles modified Glassy Carbon electrodes for electroanalytical applications

The modified electrodes show promising electroanalytical performances due to the increase of the effective surface area, to a formation of a random array of nanoparticles on the Nafion® three-dimensional substrate with intermediate diffusional behaviour between planar and convergent, and to a very small double layer capacitance. Applications exploiting the electrocatalytic properties of Ag for the detection of two chlorinated compounds (dichloromethane and halothane) are presented.
