Presenter: Michael Mertig, Ph.D., Institute of Physical Chemistry, Technische Universität Dresden, Germany

Description: In pursuit of self-propelling, thermophoretic micro- and nanoswimmers, the Mertig lab creates swimmers with feature DNA or DNA origami structures as the central element for controlled propulsion. Propelled motion is caused by a laser-induced, local temperature gradient. In order to reduce rotational diffusion of microswimmers that randomizes the directed motion, we attach linear double-stranded DNA to Janus particles. This also enables binding of cargo, enabling the creation of swimmers for the investigation of active transport at the microscale.
