| Abstract: | A hydrogen peroxide biosensor is described, which is fabricated by immobilizing HRP (horseradish peroxidase) with the gel-sol method, with TiO2 nanoparticles and PVB (polyvinyl butyral ) as the immobilization matrix. A study of the electrochemical response of the resulting sensor to the reduction of hydrogen peroxide and the factors influencing its performances has demonstrated that the TiO2 nanoparticles can enhance the current response of HRP to hydrogen peroxide. |
