A TOOTH THAT CAN DETECT BACTERIA? A recent invention of graphene nanosensor tattoo which can monitor bacteria levels inside the mouth, is very promising. The idea is combining biology and nanoscale technology into sensors which holds the potential of increased sensitivity and therefore a significantly reduced response-time to sense a potential problem. This means, being able to cure a problem before it spreads and becomes incurable.Oral bacterial contamination is a major problem in both developed and non developed countries. The rapid detection of pathogens is extremely important and has become more important because pathogens are becoming increasingly more immune to antibiotics. Early detection of pathogens are critical to preventing disease outbreaks and preserving public health. Conventional diagnostics lack ultra sensitivity and delays getting results. One of the main issues is that many infections only require very low infective doses, which require mechanisms that offer extremely high sensitivities. This also causes another problem to occur, the time it takes between sampling and getting results can be dangerous. We might be able to change all this, a team of scientists, led by Fiorenzo Omenetto at Tufts University and Michael C. McAlpine at Princeton University, have now developed a novel approach to interfacing passive, wireless graphene nanosensors onto biomaterials via silk bioresorption. They have reported their finding on March 27, 2012. "Graphene is capable of highly sensitive analyte detection," says Manu S. Mannoor. One of the most surprising facts about graphene is that it can be printed onto almost anything including water. “What we were able to demonstrate is only a prototype, 'first generation' platform that served as a proof of concept for the in situ bacterial contamination monitoring by direct interfacing of graphene nanosensors with a variety of substrates including biological tissues," says Mannoor. "Future challenges include mainly improving the selectivity of the detection system to be able to distinguish between various species of pathogenic bacteria. Reducing the sensor form factor is also another challenge facing the future development of the sensor."  NANOTECH
