Graphene Nanosensor Tattooed to Teeth Detects Bacteria

Graphene Nanosensor Tattooed to Teeth Detects Bacteria

A couple of years ago I covered research into developing a nanomaterial that could end the need for root canals. I took some criticism at the time for suggesting in that blog that root canals were unpleasant. So, despite some reluctance on my part to cover dental-related nanotechnologies, let's look once again at the latest nanotechnology being used with teeth. The technology involves a nanosensor made out of graphene that can detect bacteria in our mouths when the sensor is in a sense tattooed to our teeth. Oddly, it seems that the bacteria that the nanosensor detects is not the Streptococcus mutans bacteria that is the principal cause of tooth decay. While the research, which was initially published in the journal Nature Communications , may not combat tooth decay, it holds some promise as method for on-body health monitoring. The researchers from Tufts University and Pr...
