New technology to compress light wavelengths fourfold offers a way to focus light beyond normal wavelengths to reach nanoscales (a nanometer is a billionth of a meter) in length. “With increased brightness and resolution, microscopes will have increased accuracy at the molecular level,” says Prof. Guy Bartal of the Viterbi Faculty of Electrical Engineering. The innovation opens the way to improvements in lab-on-chip devices and bioimaging.
