Growth of Carbon, Boron Nitride and ZnO Nanotubes for Biosensors

Abstract

Nanotubes have significant portions of their atoms located at the surfaces and represent the future of biological devices. With such small dimensions, sensitivities and applications previously impossible are being made real. Not all nanomaterials are currently at the same level of proficiency, however. Carbon nanotubes are a mature, easily grown and controlled nanostructure, but boron nitride and zinc oxide are still coming into their own. Yet progress in all three species of nanotubes is making applications easier than before.
