Enhanced electroactivity and substrate affinity of microperoxidase-11 attached to pyrene-linkers π–π stacked on carbon nanostructure electrodes

Abstract

An exceptionally large electroactively connected microperoxidase-11 (MP-11) with strong affinity for organic peroxide and offering a high electrocatalytic reduction current density of 7.5 mA cm⁻² is achieved for the first time. For this, MP-11 was attached via pyrene linkers on the surface of multiwalled carbon nanotube-modified graphite electrodes.
