Ultrasensitive sensor using N-doped graphene - A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing nitrogen atoms into the carbon structure of graphene. This technique can detect trace amounts of molecules in a solution at very low concentrations, some 10,000 times more diluted than can be seen by the naked eye.

Antibiotics Weaken Alzheimer's Progression Through Changes in Gut Bacteria

Long-term antibiotic treatment in mice decreases levels of disease-causing plaques and enhances neuroinflammatory activity of microglial cells.

The research will appear in Scientific Reports.
