We research the movement of active Janus colloids within an optical entice working with experiments, theory and numerical simulations. To achieve isotropic and harmonic confinement, we prototype microparticles with a virtually uniform refractive index and confirm that, during the absence of action, the confined motion is similar to that of https://andrefg4c2.answerblogs.com/15899622/top-latest-five-epl-urban-news
