Abstract
Thin films of electroconductive poly[pyrrole-co-3-(1-pyrrolyl)propionic acid] were prepared by electropolymerization onto 3-aminopropyltrimethoxysilane modified and 3-(1-pyrrolyl)propionic acid derivatized interdigitated microsensor electrode (IME) arrays. The ω-(1-pyrrolyl) moiety on the surface of the device provides for specific adhesion of the polymer film to the device and the (N-pyrrolyl)propionic acid moiety on the polymer backbone provides for covalent attachment of bioactive molecules, such as biotin and urease, to the polymer surface. The immobilized, bioactive urease produces an ON/OFF conductimetric response traceable to analyte concentration.
