Direct electrochemistry of microperoxidase at Pt microelectrodes modified with carbon nanotubes.
Direct electrochemistry of microperoxidase (MP-11) was found at Pt microelectrodes modified with multi-wall carbon nanotubes (MWNTs). The MWNTs used as the immobilization matrix cooperatively promote the bioactivity of MP-11. When MP-11 was immobilized on MWNTs film-modified Pt microelectrodes, a pair of well-defined redox waves was obtained. The resulted stable microelectrode could be used to catalyze the reduction of H2O2 and O2.
