Nanophotonics with hybrid DNA origami structures

Advanced nanophotonic systems can be prepared by self-assembly of basic building elements (dielectric and metal micro- and nanoparticles, quantum dots, fluorescent molecules). DNA origami technology provides flexible matrices for controlled “bottom-up” preparation of hybrid photonic structures of complex shapes and precise stoichiometry with desired function. The proposed project aims at the synthesis of asymmetric photonic micro- and nanostructures whose motion can be controlled by light and at the characterization of their properties and stability. Planned experimental activities are highly interdisciplinary; the research team combines experts on microphotonics and microfluidics from the ISI CAS with experts on the synthesis of DNA origami and hybrid nanostructures from the JHI CAS. The team will design and prepare the desired photonic structures, characterize their stability in microfluidic chips, and conduct the optical manipulation and spectroscopy experiments. The control of motion of hybrid structures by light will bring new knowledge bridging the classical and quantum regime.
