Recent Updates of Chemically Modified Electrodes in Analytical Chemistry

Abstract This review article updates recent developments in chemically modified electrodes (CMEs) towards analytical applications for the year of 2000–2002 with 179 references. The broad topics are subdivided into four main categories: i) physisorption/chemisorption, ii) covalently linked, iii) homogenous (uniform) multilayer and iv) heterogeneous (non‐uniform) multilayer CMEs. The criteria for the preparation of CMEs in elecrocatalytic systems are clearly described in Section 1. Some of the encouraging results related to Au‐nanoparticles for DNA detection and new ceramic carbon, carbon nanotubes, copper‐plated screen‐printed and Nafion/lead ruthenate pyrochlore CMEs for catalytic application were especially discussed in this review.
