Optical nanoantennas set the stage for a NEMS lab-on-a-chip revolution

Tuesday, February 24, 2015 - 11:30 in Physics & Chemistry

Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the Australian scientists who created them. The new antennas are cubic in shape. They do a better job than previous spherical ones at directing an ultra-narrow beam of light where it is needed, with little or no loss due to heating and scattering, they say.
