- By immobilizing glucose oxidase (GOD) on a nanocomposite containing hydroxyl fullerenes (C60-OH) and TiO2 nanoparticles, a new type biosensor was prepared for glucose detection. The cyclic voltammograms (CVs) of GOD on the nanocomposite modified glassy carbon electrode (GCE) was quasi-reversible. The heterogeneous electron transfer constant (ks) and the formal potential (E§ï) of the Chi/GOD/C60-OH-TiO2/GCE were 3.0 s 1 and -0.248V, respectively. The Chi/GOD/C60-OH-TiO2/GCE responsed linearly to glucose from 0.05 to 0.85 mM. The apparent Michaelis-Menten constant (kmapp) and detection limit of the Chi/GOD/C60-OH-TiO2/GCE were 1.17 mM and 0.05 mM, respectively.
