Abstract
Active nematics are non-equilibrium liquid crystalline systems composed of self driven particles whose motility creates flows that lead to perpetual changes in the local nematic director. We employ magnetically manipulated microdisks and nanorods as local probes of quasi-2D active nematic films. By observing the hydrodynamic interactions between the probes and the films, we are able to obtain novel information about the mechanical and dynamical properties of the system.
