  • Title: Nanopillar array structures for enhancing biosensing performance.
    Author: Anandan V, Rao YL, Zhang G.
    Journal: Int J Nanomedicine; 2006; 1(1):73-9. PubMed ID: 17722264.
    Abstract:
    Fabrication of metallic nanopillar array structures and their application as electrodes in electrochemical-based biosensors are discussed in this report. Vertically standing nanopillar array structures were fabricated using an electrodeposition technique and their electrochemical characteristics were evaluated. For possible use in biosensing applications, these standing nanopillars should have sufficient mechanical stability to sustain the capillary forces caused by the nanopillar-liquid interactions in aqueous environment and should provide increased signal response in an electrochemical process. Our results showed that the developed nanopillar arrays were mechanically stable in aqueous environments and the nanostructured electrodes exhibited increased electrochemical response compared with flat electrodes.
