Abstract

In this paper, we compared the direct electron transfer and electrocatalytic properties of bilirubin oxidase (BOD) immobilized at two kinds of carbon nanotubes (CNTs), bamboo-CNTs and uniform-CNTs. X-ray diffraction and X-ray photoelectron spectroscopy results indicated that the ratio of sp 2 band to sp 3 band and the content of oxygen-containing groups at the surface of uniform-CNTs were higher than that of bamboo-CNTs. Moreover, uniform-CNTs can be well separated at the surface of the electrode. Better electrochemical and electrocatalytic properties of BOD immobilized at uniform-CNTs were shown.
