Nanophotonics and biophotonics
Nano photonics is the study of the behavior of light on the nano meter scale, and of the interaction of nano meter-scale objects with light. It is a branch of optics, electrical engineering, and nanotechnology. It often involves metallic components, which can transport and focus light by means of surface plasmon polaritons. Bio photonics can also be described as the advance and application of optical techniques particularly imaging, to study of biological molecules, tissue and cells. One of the main benefits of using optical techniques which make up bio photonics is that they reserve the reliability of the biological cells being examined, i.e. scattering material, on a microscopic or macroscopic scale.
