Abstract

Stable films made from chitosan (CS) on pyrolytic graphite electrode (PGE) gave direct electrochemistry for incorporated enzyme nitrate reductase (NR). Cyclic voltammetry of CS / NR films showed a pair of well-defined and nearly reversible redox peaks at about -0.430 V vs. SCE at pH 7.0 phosphate buffers.
