We study the motion of Energetic Janus colloids within an optical trap employing experiments, principle and numerical simulations. To obtain isotropic and harmonic confinement, we prototype microparticles with a virtually uniform refractive index and validate that, in the absence of action, the confined motion is similar to that of optically https://cesarw1y0v.jaiblogs.com/40765263/epl-things-to-know-before-you-buy
