Electroactive conducting polymers(ECPs)

such as polypyrrole(PPy) and polyaniline(PANi)

have shown potential applications in the biomedical field.ECP has been the focus of attentions by scientists

biological

tissue engineering as well as medical professionals.The current researches concentrate on biocompatibility

tissue engineering

protein separation

DNA repair adsorption

controlled drug delivery

biosensors and so on.ECP as scaffolds might find applications in regulating functions and regenerating of neuron

brain cells

cardiac stem cells and orientation induced tissue regeneration.Electric stimulation was shown to affect cell prolification and differentiation.Recent progresses in conductive polypyrrole and polyaniline in biomedical field are reviewed in this paper.Some potentially rewarding research directions are suggested.
