Abstract

We describe development techniques for nanowire-based nano-biosensors. We synthesized zinc oxide nanowires in a custom ambient Chemical Vapor Deposition (CVD) system. We performed characterizations on synthesized nanowires and functionalized them to experiment with immobilization of carboxylic acid moieties on the surface of nanowires for biosensing applications. We analyzed modified and unmodified zinc oxide (ZnO) nanowires with oleic acid to sense biomolecules along with the sensing mechanism.
