Rice University researchers studying the effect of light on pinwheels (left) and single C-shaped (right) gold nanoparticles have found an unknown effect on single particles. Stimulating the particles just right produced a near-perfect modulation of the light they scatter via their plasmonic response. The discovery may become useful in the development of chips for next-generation optical components for computers and antennas. Courtesy of the Link Research Group

Light triggers gold in unexpected way

Rice scientists surprisingly made a discovery that suggests that exciting the microscopic particles just right produced a near-perfect modulation of the light they scatter. This...
