Advanced biological functionalization for graphene biological sensors on flexible subtrate

Published : 1 January 2023

The need for biological sensing solutions is constantly growing. Amid targeted applications, some require biosensor with high sensitivity. At CEA LETI we are running a project that aim at developing novel innovative wound dressing equipped with graphene biological sensors to track wound bacterial proliferation indicative of sepsis. The sensor is a Solution gated graphene FET-like sensor. In the Framework of that project, we develop and test innovative biological functionalization strategy adapted to the graphene sensors. This functionalization protocol, once established and tested through several reference instruments will be implemented on the sensor. The impact of the biological functionalization on the final sensing performance will be studied.
