Abstract
A nanodevice includes an array of metal nanorods formed on a substrate. An electropolymerized electrical conductor is formed over tops of a portion of the nanorods to form a reservoir between the electropolymerized conductor and the substrate. The electropolymerized conductor includes pores that open or close responsively to electrical signals applied to the nanorods. A cell loading region is disposed in proximity of the reservoir, and the cell loading region is configured to receive stem cells. A neurotrophic dispensing material is loaded in the reservoir to be dispersed in accordance with open pores to affect growth of the stem cells when in vivo.
