Graphene tooth addition can detect illnesses

0

Princeton University scientists have developed a graphene-based sensor that can be applied to a human tooth in order to detect and communicate to a remote location whether the host has an infection or other illness.

The sensor, which has an atom-thick graphene base, is composed of a peptide – which is in turn created from two peptides, one of which comes from a tropical frog – and an RFID chip. The peptides are used to detect bacteria and the RFID chip transmits the results to someone who can make sense of them.

At the moment the sensor is rather fragile and brushing your teeth would likely remove it but the scientists eventually hope to commercialise the technology.
