Interfacing Conducting Polymers and Biological Macromolecules: A Case Study ofInsecticide Biosensor Development

摘要

The creation of smart materials is a current goal of many laboratories includingour own. We are involved in studying a number of thin film and monolayer systems which share the common features of involving highly conjugated conducting organic polymers and the evolved properties of specific biological macromolecules. In this report we describe a generic 'cassette' methodology for immobilizing biotinylated biological macromolecules to hydrophobic surfaces using a novel class of conducting copolymers of polythiophene. These copolymers are derivatized with long alkyl chains and biotin moieties to bind, respectively, to the
