Abstract
For breath analyses, volatile detectors capable of sensing extremely low concentrations in the sub-ppm range are required. Novel room temperature sensors were fabricated based on ultraviolet light activation of nanoparticulate metal oxide surfaces using light emitting diodes. These sensors gave reversible electrical resistance changes in the low ppm/ppb range to volatile organic compounds found in breath, including acetone, acetaldehyde, pentane and ethanol. © 2008 IOP Publishing Ltd.
