Polypyrrole based nano-biosensor for sensing low concentrations of hydrogen peroxide

This paper discuss about a novel technique of developing a nano-structured polypyrrole biosensor for measurement of very low concentrations of hydrogen peroxide in liquid media. The proposed fabrication method is very effective in growing a nano-structured conducting polymer layer on a planar conducting substrate. In addition enzyme loading was done under a high electric field of 1000V/m. The developed sensor provides a liner range of 0-200μM of hydrogen peroxide and a measurement sensitivity of 6.5Acm-2M-1.
