Novel nanobiocomposites multiwalled carbon nanotube-poly(vinyl alcohol)-glucose oxidase have been successfully prepared by a simple solution-evaporation method. The morphology and performance of the multiwalled carbon nanotube-poly(vinyl alcohol) -glucose oxidase film have been characterized by atomic force microscopy, cyclic voltammetry, and amperometry. The multiwalled carbon nanotube and glucose oxidase were observed to be homogeneously dispersed throughout the poly(vinyl alcohol) matrix. When compared with bare glassy carbon electrode, the sensitivity to hydrogen peroxide is greatly improved by about 115 times at multiwalled carbon nanotube-poly(vinyl alcohol) modified glassy carbon electrode. The glucose biosensor sensitivity was strongly influenced by the glucose oxidase concentration within the multiwalled carbon nanotube-poly(vinyl alcohol)-glucose oxidase composite.
