Abstract
A novel amperometric biosensor for the detection of hydrogen peroxide was d escribed. The biosensor was constructed by electrodepositing HRP/PPy membra ne on the surface of ferrocenecarboxylic acid mediated sol-gel derived comp osite carbon electrode. The biosensor gave response to hydrogen peroxide in a few seconds with detection limit of 5.0 x 10(-5) M (based on signal:nois e = 3). Linear range was upto 0.2 mM. The biosensor exhibited a good stabil ity. (C) 2001 Elsevier Science B.V. All rights reserved.
