Abstract
We report on a composite matrix composed of epoxy copolymers P (GMA-co-MPC) and acetylene black that can be used to entrap cytochrome P450. The composite provides a biocompatible microenviroment and can substantially accelerate the electron transfer between the cytochrome P450 and the electrode. The electrochemical response is characterized by a pair of well-defined redox peaks for the heme Fe(II/III) redox couples were observed at −483 mV (vs. SCE). The immobilized cytochrome P450 exhibits excellent electrocatalytical activity to diethylstilbestrol (DES). The amperometric response varied linearly with the concentration of DES in the 0.2 to 2.8 μM concentration range. The biosensor displays a detection limit 5.9 × 10-8 mol L-1 and thus represents a promising candidate for studying the electrochemistry of cytochrome P450s and its sensing applications.
