Projektinformationen
The question is whether nanostructures with typical dimensions of the wavelength of visible light can be propelled and steered in liquids in 3D with nanometer precision just by illuminating them from time to time with moderately focused light pulses of linear or circular polarization. The team plans to make use of tailormade plasmonic nanostructures exhibiting strong optical spin-orbit coupling. Through this coupling the direction of enhanced light absorption and scattering becomes highly dependent on the orbital angular momentum of the incident photons. This approach should provide a general method to control the movement of nanometer sized vehicles in liquid environments. A successful demonstration would be the basis for novel types of experiments in the life sciences, for instance investigations and manipulations within living cells, or the transport and processing of functional cargo attached to such nano-drones.
