Graphene based wireless 'tooth tattoo' sensor to detect bacteria


Manu Sebastian Mannoor, Graduate student
Mechanical and Aerospace Engineering, Princeton University


The fundamental question we are trying to answer is whether we can directly interface highly sensitive sensors based on nanomaterial graphene with biological materials, such as tooth enamel and skin. Further, we have investigated the capability of such bio-interfaced sensors to demonstrate on-body, real-time monitoring of disease causing pathogens.


We fabricate our sensors in the dust-free environment of a clean-room facility. We do the characterization of devices using various hardware and equipment in our lab.… Read the entire snippet
