Rigid, dried, and trapped active colloidal matter

If you have a question about this talk, please contact Michael te Vrugt .

Active matter systems – such as a suspension of microorganisms or synthetic microswimmers – dissipate energy and maintain exciting collective dynamics. This talk will discuss three distinct experimental colloidal systems. The first part of the talk will be about the emergence of rigidity from phoretic self-interactions in an active polymer. Then, I will explain the experimental observed morphologies of electric-field-driven cracks in dried dispersions of ellipsoids. Finally, I will talk about a method to trap microparticles outside a laser beam using phoretic and hydrodynamic interactions.

This talk is part of the DAMTP Statistical Physics and Soft Matter Seminar series.
