Optical nanoantennas enable efficient multipurpose particle manipulationChicago IL (SPX) Jan 16, 2012 University of Illinois researchers have shown that by tuning the properties of laser light illuminating arrays of metal nanoantennas, these nano-scale structures allow for dexterous optical tweezing as well as size-sorting of particles. "Nanoantennas are extremely popular right now because they are really good at concentrating optical fields in small areas," explained Kimani Toussaint, Jr., an assistant professor of mechanical science and engineering at the University of Illinois at Urbana-Champai ... read more |
