Low-powered Nanotweezers May Benefit Cellular-level Studies By Demonstrating New Capabilities

Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power “optical nanotweezers” can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples. “We already know that plasmonic nanoantennas enhance local fields by up to several orders of magnitude, and thus, previously showed that we can use these structures with a regular CW laser source to make...

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...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
