title: Surfactant-assisted direct electron transfer between multi-copper oxidases and carbon nanotube-based porous electrodes.
abstract: The effects of pre-treatment with surfactants on the electrocatalytic reaction of multi-copper oxidases were quantitatively evaluated using a well-structured carbon nanotube forest electrode. It was found that both the charge polarity of the head group and the aromatics in the tail part of the surfactants affect the efficiency of enzymatic electrocatalysis.
