Using gold nanoparticles, researchers at the University of Central Florida in Orlando can noninvasively detect low levels of glucose in human tears.

"The detection limit is low enough to detect levels of glucose in healthy persons," chemistry professor Florencio Hernández told C&EN. "The idea is to use this method to determine glucose concentrations at very early stages. You can actually detect potential diabetic problems before diabetes becomes a problem."
