A novel film of chitosan-gold nanoparticles is fabricated by a direct and facile electrochemical deposition method and its application in glucose biosensor is investigated. HAuCl 4 solution is mixed with chitosan and electrochemically reduced to gold nanoparticles, which can be stabilized by chitosa...
