چکیده انگلیسی

We have demonstrated the applicability of cyclic voltammetry and rotating disk electrode techniques for the characterization of microparticle monolayers. We have tested experimentally the recently developed theoretical model for the determination of surface coverage of spherical particle monolayer by means of diffusion current measurements. We have verified our electrochemical results by means of optical microscopy. We have found that the model applicability range increases with the decrease of the adsorbed particle size. For the 1.16 μm particles we have found a good agreement between our theoretical and experimental results at the surface coverage larger than 0.45. Our results suggest that the voltammetric characterization of thin porous films may have practical applications for, e.g., detection and determination of surface coverage of bacteria, cells or other objects in the micron size range.
