Abstract:
1. A nanostructured surface for detecting an analyte comprising: a glass or silicon substrate; an array of metallic nanopillar islands on the glass or silicon substrate, wherein each metallic nanopillar island comprises a metal base layer on the glass or silicon substrate and a plurality of metallic nanopillars on the metal base layer, and wherein portions of the glass or silicon substrate between adjacent metallic nanopillar islands are free of the metal base layer wherein the metallic nanopillars have an aspect ratio in a range of about 5:1 to about 500:1; and a driver circuit in electrical contact with at least one metallic nanopillar island through the metal base layer connected to the driver circuit through a metallic bridge or an electrical lead on or through the substrate, wherein the driver circuit generates an electrical potential sufficient to cause at least a portion of the metallic nanopillars of the at least one metallic nanopillar island to shift position.
