Abstract

The coupling of a photodynamic protein to an electroactive polymer may be employed in opto-electronic signal transduction for optical displays, color mimicking and biosensor applications. We have synthesized a novel biomaterial, biotin-LC-hydrazide substituted poly(3-undecylthiophene-co-3-thienylcarboxaldehyde) [B-PUAT], which is capable of incorporating any biotinylated molecule through a bridging streptavidin protein. A long spacer group between the conjugated polymer backbone and the biotin side group improves monolayer formation at the airwater interface and enhances the material's ability to bind protein. The LB technique has been employed to couple this biomaterial and streptavidin through the well known biotin-streptavidin complexation. Biotinylated phycoerythrin [B-PE] is incorporated into the above monolayer by binding the unoccupied biotin binding sites on the bound streptavidin.
