The biosensor was constructed by electrodepositing HRP/PPy membrane on the surface of ferrocenecarboxylic acid mediated sol-gel derived composite carbon electrode. The biosensor gives response to hydrogen peroxide in a few seconds with detection limit of 5×10-7 mol·L-1 （based on signal : noise=3）. Linear range is up to 0.2 mmol·L-1.展开更多
