Hydrophobic vs. hydrophilic particle detection using mercury electrode. What causes the difference?

The electrochemical techniques employing microelectrodes and high sensitivity time resolved recording of amperometric signals allow detection in real time of single events – oxidation or reduction of nano- and microparticles. In contrast to the voltammetry of solid microparticles where particles are already immobilized on the electrode surface, we shall treat the case where renewable electrode is exposed to the dispersion of organic microparticles. In that case the initial attachment is established by interplay of hydrodynamic and surface forces giving rise to specific signal for each particle attachment.
