A tiny step for a protein, a giant leap for nanotechnology : Nanotechnological applications of biomolecular motors

Orateur : Dr. Till Korten (Group BioNanoTools, BCUBE-TU Dresden, Allemagne)

Abstract : Proteins have been optimized by evolution for billions of years to work on a nanometerscale. Therefore, they are extremely promising for nanotechnological applications. In particular, cytoskeletal motor proteins are ideally suited for nanotechnological devices, because they perform mechanical work using the chemical energy of ATP-hydrolysis. This lecture will give an overview of important advances in the field of nanotechnological applications of biomolecularmotors. Key technologies necessary to make full use of molecular motors in artificial environments include (i) spatial guiding allowing directional control, (ii) molecular switches that allow temporal control, and (iii) versatile methods of molecular attachment allowing loading and unloading of cargo. With these technologies, it was possible to develop more and more complex devices such as molecular sorters, molecular concentrators, detectors and biocomputation devices.
