Researchers Develop “Tooth Tattoo” to Help Detect Bacteria in the Mouth

A team of researchers led by Dr. Michael McAlpine of Princeton University have developed a gold- and carbon-based biosensor that can be affixed to a tooth [1]. The purpose of the sensor, which is made up primarily of a very strong form of carbon called graphene, is to detect sequences of DNA that are specific to pathogenic bacteria.
