Electrochemically controlled release of adenosine 5′-triphosphate from polypyrrole film
Abstract
Polypyrrole (PPy) film is synthesized by anodic polymerization of pyrrole onto the surface of a platinum electrode in the presence of toluene-p-sulfonate and the film is used for the controlled release of the neurotransmitter, adenosine 5′-triphosphate (ATP).
