Led by Professor Romain Quidant, researchers at the Institute of Photonic Sciences has developed optical nanotweezers that use light to transport tiny particles in three dimensions. Without physically touching the tiny objects, this highly-advanced device shapes the light to envelop and trap a microscopic object by focusing a beam of laser light, which create a “self-induced back action.”
