Abstract
A composite polymer carbon fiber electrode modified with Nafion and ce llulose acetate is described, The incorporation of ion exchanging poly mer to the cellulose acetate domain allows the binding of counterionic reactants, while maintaining the size exclusion discriminative proper ties of cellulose acetate. In vivo voltammetry, the modified microelec trode inhabits the oxidation of some neurotransmitter metabolites and electroactive compounds, such as DOPAC, 5-HIAA, HVA, AA and UA; and su ccessfully detects the oxidative current of neurotransmitter DA.
