New look for nanodetection
Abstract:
Optical physicists in the US have invented a way of detecting single nanoparticles in real time. Devised by Filipp Ignatovich and Lukas Novotny of the University of Rochester in New York, US, the new technique involves measuring the amplitude of light scattered from the particles and can detect objects as small as 5 nanometres in diameter. The researchers say the method could be used to detect viruses or to build sensors that provide early warning of biological weapons.
