Abstract
A nanowire electrode array has a plurality of vertical nanowires extending from a substrate, each of the nanowires including a core of unitary first dielectric material that also covers the substrate and is unitary with the substrate. Each core has a sharp sub-100 nm diameter tip and a wider base, electrode leads on sidewalls to the tip of the nanowire, and second dielectric covering the electrode leads. The tips in the array can penetrate individual cells in cell culture, such as a mini-brain culture. The substrate can include a window for simultaneous optical imaging and electrophysiological recording.
