We report on a high performance glucose biosensor based on the immobilization of glucose oxidase (GOx) with chitosan onto TiO 2 nanotube arrays modified by Prussian blue (PB) and Au. The titania nanotube arrays were grown directly on a Ti substrate using anodic oxidation, with a thin Au film coated...
