Neuro-chemical sensor with inhibition of fouling on nano-electrode

Abstract:

A biosensor includes an array of metal nanorods formed on a substrate. An electropolymerized 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 and close responsively to electrical signals applied to the nanorods. A dispensing material is loaded in the reservoir to be dispersed in accordance with open pores.
