Ensembles of self-propelled species have been shown to result in a variety of novel steady states and dynamic processes. We have been investigating several different systems of varying sizes and shapes including microtubule cytoskeletal filaments that glide along suraces powered by kinesin-1 motor proteins, droplets of liquid crystals that shed miscelles to propel and stir their insides, and recently individual self-propelled enzymes. These systems offer a variety of controls on the size, shape, aspect ratio, and tuneable interactions enabling us to inspect new phenomena of active systems.
