中文摘要	chemically modified electrodes (cmes) were prepared by adsorbing different dyes, including methylene blue (mb), toluidine blue (tb) and brilliant cresyl blue (bcb), onto glassy carbon electrodes (gce) with anodic pretreatment. the electrochemical reactions of adsorbed dyes are fairly reversible at low coverages. the cmes are more stable in acid solutions than in alkaline ones, which is mainly due to decomposition of the dyes in the latter media. they exhibit an excellent catalytic ability for the oxidation of nicotinamide coenzymes (nadh and nadph). the formation of a charge transfer complex between the coenzyme and the adsorbed mediator has been demonstrated using a rotating disk electrode. the charge transfer complex decomposition is a slow step in the overall electrode reaction process. some kinetic parameters are estimated. dependence of the electrocatalytic activity of the cmes on the solution ph is discussed.
