Motorized Nanostructures from Light-responsive Molecular Machines: Structure and Dynamics

Anastasia Christoulaki (MSC, Université Paris Cité)

with Eric Buhler

Abstract :
Nanostructures bearing light driven molecular motors are studied with the aim to test the efficiency of the molecular motors in transferring mechanical work to the nanostructures, thus achieving the smallest self-propelling molecular machines that will lead to new applications in nanotechnology and nanomedicine. Scattering techniques (light, X-rays, neutrons) are employed to measure the structure and dynamics of the nanostructures upon activation of the motors by UV light. Among them the use of heterodyne light scattering technique with a novel experimental setup allows for the detection of a drift velocity, indicating propulsion behavior of these active nanostructures.
