Abstract:Cellobiose dehydrogenase (CDH) is applied as a bioelectrocatalyst in biosensors because its mobile cytochrome domain is capable of direct electron transfer. This study investigates the electron transfer mechanism of CDH molecules embedded in the polycation polyethyleneimine (PEI), which has been reported as a current‐boosting component of CDH‐based biosensors. By immobilizing different concentrations of CDH and its isolated cytochrome domain in PEI films, we found that increasing concentrations of cytochrome e… Show more
