Microfabricated glucose sensor based on single-walled carbon nanotubes

This paper describes a novel glucose sensor that uses the hydrogen-specific gas sensing capability of single walled carbon nanotubes (SWCNTs) assembled on microelectrodes. Highly specific glucose sensing was demonstrated using buffered sample solutions with clinically significant concentrations. The proposed approach enables a simple but powerful bio-sensor reliably operating with a completely new principle, and opens up novel device applications where functional nano-components are integrated into a bioMEMS device.
