Graphene Based E-Nose Could Sniff out Cancer

Graphene Based E-Nose Could Sniff out Cancer
A graphene-based biosensor able to detect lung cancer in breath samples could offer more accuracy than previous e-nose devices.

While detecting biomarkers in breath is a promising way to identify diseases, typical e-nose devices suffer from inaccuracies. To increase the efficiency of the technology, the team from the University of Exeter developed biosensors using patterned, multi-level graphene electrodes. According to the team, the patterned graphene is able to detect the common lung-cancer biomarkers ethanol, isopropanol, and acetone in exhaled breath and in various concentration levels.
