Carbon nanostructures-based bio/chemical sensors

Nanostructures, such as nanowires, nanobelts, nanosprings and nanotubes, are receiving growing interest as transducer elements of bio/chemical sensors as they provide high sensitivity, multiplexing, small size and portability. Single walled carbon nanotubes (SWNTs) and graphene are one such class of nanostructure material that exhibit superior sensing behavior due to their large surface carbon atoms that are highly responsive to surface adsorption events. Further, their compatibility with modern microfabrication technologies, facile functionalization with molecular recognition elements make them promising candidates for bio/chemical sensors applications.

In this presentation, I will report our recent results on nanosensors based on SWNTs and graphene film and nanomesh combined with biological receptors such as aptamers, antibodies and binding proteins, and chemical receptors such as conducting polymer, metals and metal nanoparticles to develop highly sensitive, selective, rapid and cost-effective label-free chemiresistor/field-effect transistor nano-bio/chemical sensors for applications in health care, homeland/personal security, environmental monitoring, etc.
