Plasmonics and optical tweezers - nanotechnology that manipulates with light

Ever since Roman glass blowers made the Lycurgus cup, some 2,400 years ago, researchers and engineers have figured out to do all kinds of things with light, be it in optical fiber communications; the use of lasers for welding, cutting and surface modification of materials; photonic gyroscopes in aviation; or optical switches in computing. As a general field of science, photonics defines the knowledge devoted to the generation, transmission, detection, control and handling of light. One sub-domain, nanophotonics deals with the manipulation and emission of light using nanoscale material and devices. One of the sizzling hot topics within nanophotonics is plasmonics, which holds the promise of a class of subwavelength-scale optoelectronic components that could form the building blocks of a chip-based optical device technology that is scaleable to molecular dimensions. Here, we report on the latest achievements of a Spanish-French group of researchers that brings the exiting concept of an optically driven lab-on-a-chip closer.
