Light-driven simultaneous active and diffusive behaviour of asymmetric microclusters using a photophoretic trap in air

Light-driven simultaneous active and diffusive behaviour of asymmetric microclusters using a photophoretic trap in air

Active and diffusive motion in Brownian particles are regularly observed in fluidic environments, albeit at different time scales. Here, we experimentally study the dynamics of highly asymmetric microclusters trapped in air employing photophoretic forces generated from a loosely focused laser beam,...
