Microparticles Captured By Silicon Microring Resonator

Silicon microring resonator could help advance nanomanipulationTo trap and hold tiny microparticles, engineers at Harvard have "put a ring on it," using a silicon-based circular resonator to confine particles stably for up to several minutes.The advance, published in the June 14 issue of Nano Letters, could one day lead to the ability to direct, deliver, and store nanoparticles and …
