Permeability improvement of electropolymerized polypyrrole films in water using magnetic hydrophilic microbeads.
The electrochem. polymn. of polypyrrole films onto magnetically immobilized hydrophilic microbeads was carried out. Poly(pyrrole-pyrene)-microbeads coatings display thus higher permeability in water towards the diffusion of ferrocyanide than a pure poly(pyrrole-pyrene) film. In addn., the modulation of this permeability through an applied magnetic field that attracts the microbeads on the electrode surface or pushes back them was shown. Moreover, a glucose biosensor was prepd. by adsorbing and electropolymg. on a platinum electrode, an aq. mixt. contg. glucose oxidase, amphiphilic pyrrole monomer and microbeads attracted by a magnet. The presence of microbeads inside the biocoating, markedly increases the biosensor performance. [on SciFinder(R)]
