An important practical application of the ion gate membrane could be the controlled delivery of drugs, which can be accumulated in the membrane e.g. during oxidation and then released by electrochemically controlled reduction of the membrane. Polypyrrole (PPy) is particularly suitable for this purpose because the monomer is nontoxic and the ...Author: Kyösti Kontturi, Päivi Pentti, Göran Sundholm

Dec 22, 2006 · Polypyrrole (PPy) is a conjugated polymer that displays particular electronic properties including conductivity. In biomedical applications, it is usually electrochemically generated with the incorporation of any anionic species including also negatively charged biological macromolecules such as proteins and polysaccharides to give composite materials.Author: D.D Ateh, H.A Navsaria, P Vadgama

Aug 08, 2015 · Over the last 40 years, electrically conductive polymers have become well established as important electrode materials. Polyanilines, polythiophenes and polypyrroles have received particular attention due to their ease of synthesis, chemical stability, mechanical robustness and the ability to tailor their properties. Electrochemical synthesis of these materials as films have proved to be a ...Author: B. Alshammary, F. C. Walsh, P. Herrasti, C. Ponce de Leon

A platform for controlled drug delivery using a conductive‐polymer substrate has been created. Through the incorporation of biotin into the conductive polymer polypyrrole (PPy) and the subsequent attachment of the desired drug molecule (such as nerve growth factor, NGF) via a streptavidin linker, an applied potential can trigger release of the drug from the polymer surface (see figure).Author: Paul M.

Jan 24, 2012 · We describe a new temperature and electric field dual-stimulus responsive nanoparticle system for programmed drug delivery. Nanoparticles of a conducting polymer (polypyrrole) are loaded with therapeutic pharmaceuticals and are subcutaneously localized in vivo with the assistance of a temperature-sensitive hydrogel (PLGA-PEG-PLGA). We have shown that drug release from the …Author: Jun Ge, Evgenios Neofytou, Thomas J. Cahill, Ramin E. Beygui, Richard N. Zare
