The use of electrochemically grown polymers on metallized electrodes to reduce electrode fouling in biological matrices

The use of electrochemically grown polymers has expanded dramatically in th e last couple of years, and they are now well established as membranes for immobilizing components. The evidence here for their anti-fouling propertie s is good. The poly(1,3-diaminobenzene)-covered electrodes performed well i n the buffer, urine, plasma and serum samples, but not so well in the blood . The Ru/Rh/Pt, Rh/Rh and the Pt-on-glassy carbon electrodes covered with p oly(1,3-diaminobenzene) were the best electrodes in the blood. The Pt disc seemed to exhibit the largest irrepeatability in most of the biological mat rices.
