Optical nanoantennas set stage for lab-on-a-chip

摘要

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 Australian scientists who created them. The cubic-shaped antennas are said to perform better than their spherical counterparts at directing an ultra-narrow beam of light, with little or no loss due to heating and scattering.
