Poly(Pyrrole)-Poly(N-Methylpyrrole) Composite Matrix for Amperometric Biosensor Design

摘要

Electrochemical copolymerization of pyrrole-N-methyl pyrrole has been carried out galvanostatically on platinum substrate. The polypyrrole-poly (n-methylpyrrole) composite films were subjected to electrical, spectral and morphological characterizations. Glucose biosensor was further fabricated based on the immobilization of glucose-oxidase in the composite films by crosslinking via glutaraldehyde. The effect of phosphate and acetate buffer was investigated. The biosensor exhibited an excellent linear response for a wide range of glucose concentration from 0Â mM to 50Â mM in both the buffers at pH 7.4. However, the sensitivity of the developed biosensor in the presence of a phosphate buffer was found to be higher.View full textDownload full textKeywordselectropolymerization, glucose biosensor, poly (n-methyl pyrrole), polypyrroleRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00914037.2010.504173
