Graphene Chemical Sensor Project

Metadata Updated: May 2, 2019

Develop graphene based miniaturized chemical sensors that will be able to detect gaseous and volatile molecules with high sensitivity, good reproducibility and wide operating environment, including extreme conditions.[HTML_REMOVED] The sensor uses graphene based[HTML_REMOVED]devices to sense the surface potential of a graphene channel exposed to an analyte. When analyte molecules adsorb onto the graphene surface, they induce a local change in electrical resistance. This effect is very pronounced in graphene due to the high surface area; high electrical conductivity; and inherent low noise, which makes the changes in resistance detectable.[HTML_REMOVED]
