Electrical stimulus based drug delivery from PPy coated PVDF fibers. Fluorescent images show Alexa Fluor™ 350 conjugated streptavidin bound to the biotin available in the PPy coating (A) before and after (B) 5 min (C) 10 min or (D) 15 min of electrical stimulation at 200 mV/mm and 1 Hz (E) Quantification of fluorescence intensity demonstrates a decrease after 15 min of stimulation (not significant, p = 0.064).
