ABSTRACT
Conducting polymer molecular interfaces have been implemented to modulate biological functions of fructose dehydrogenase, pyruvate oxidase and Saccharomyces cerevisiae at the electrode surface by adjustment of electrode potential. The enzyme activity of the polypyrrole-interfaced fructose dehydrogenase was electronically modulated by means of electron transfer between the enzyme and the electrode surface. The enzyme activity of polypyrrole-interfaced pyruvate oxidase was modulated by an electronically driven change of substrate concentration. The gene expression in polypyrrole-interfaced Saccharomyces cerevisiae was electronically induced by a change in the phosphate concentration.
