Nanostructured aligned CNT platforms enhance the controlled release of a neurotrophic protein from polypyrrole

An aligned CNT array membrane electrode has been used as a nanostructured supporting platform for polypyrrole (PPy) films, exhibiting significant improvement in the controlled release of neurotrophin. In terms of linearity of release, stimulated to unstimulated control of NT-3 release and increased mass and % release of incorporated NT-3, the nanostructured material performed more favourably than the flat PPy film.
