Graphene biosensor could provide early lung cancer diagnosis

A team of scientists from the University of Exeter has developed a new technique that could create a highly sensitive graphene biosensor with the capability to detect molecules of the most common lung cancer biomarkers.

The new biosensor design could revolutionise existing electronic nose (e-nose) devices, that identify specific components of a specific vapour mixture - for example a person's breath - and analyses its chemical make-up to identify the cause.

The research team believe the newly developed device displays the potential to identify specific lung cancer markers at the earliest possible stage, in a convenient and reusable way - making it both cost-effective and highly beneficial for health service providers worldwide. The research is published in the Royal Society of Chemistry's peer-reviewed journal Nanoscale.
