Tue 611:23-14:00P<strong>10</strong>.25Self-organization with light activated microswimmersJeremie Palacci, 1 Stefano Sacanna, 1 David Pine, 1 and Paul Chaikin 11 CSMR, NYU, 4 Washington Place, <strong>10</strong>012, New York, USAAt first we present and characterize a novel type of active synthetic microswimmers activated bylight. The particles convert radiative into mechanical energy and thus constantly maintain thesystem out-of-equilibrium. Experimental consequences of the presence of active agents or ”activebath” are presented. The analogies with equilibrium situation will be discussed eg ”hot” particles,depletion interaction. Nevertheless we will stress the additional properties originated in the outof-equilibriumnessof the system.25
