We study the motion of active Janus colloids in an optical entice applying experiments, idea and numerical simulations. To obtain isotropic and harmonic confinement, we prototype microparticles with a virtually uniform refractive index and confirm that, during the absence of exercise, the confined movement is similar to that of optically https://spencerlet65.gynoblog.com/17587022/an-unbiased-view-of-epl
