sairoy on 10 Aug 19Cell manipulation using optical traps was first indicated by Bell Laboratories using visible argon laser light and infrared light. Movement of a micron-sized dielectric particle is convinced by the direct transfer of photon momentum to a non-absorbing particle during refraction and reflection, which is the radiation pressure. The optical force from a high intensity focused Gaussian profile laser has scattering (the process in which electromagnetic radiation or particles are deflected diffused.) and gradient force components, which gives a valid point of stable equilibrium near the beam focus. Particles are trapped being across by the gradient force, while around an axis motion of the particle is controlled by the scattering forces. The wavelength of light (dp>> λ) is less than for cells, ray optics have been used to derive the radiation force from scattering of the incident light momentum.
