OT have been originally developed by A. Ashkin 30 years ago and has been particularly successful in studying a variety of biological systems in recent years. The possibility to trap particles into OT is governed by a transfer of momentum between light and matter with the key mechanism being the light scattering. Many methods has been used in order to calculate distribution of scattered light and optical forces. Mostly used are Generalized Lorenz-Mie theory (GLMT), T-Matrix and Coupled dipoles method. However, even Finite Elements Method (FEM) might be used as well. Especially FEM is unique in an ability to combine calculations of optical forces with other physical effects such as heating, temperature distribution, fluid flows, electro-osmotic effects, etc. Workplace Institute of Scientific Instruments Contact Martina Šillerová, sillerova@ISIBrno.Cz, Tel.: 541 514 178 Year of Publishing 2016
