  • Ultra-thin Superlattices From Gold Nanoparticles for Nanophotonics

    The group "Colloids and Nanooptics" of Prof. Dr. Matthias Karg at the Institute of Physical Chemistry has come up with a simple yet precise technique for developing highly ordered particle layers. The group is using tiny, soft and deformable spherical polymer beads with a hydrogel-like structure. Hydrogels are water-swollen, three-dimensional networks. For example, we are familiar with these structures as super-absorbers in babies' nappies that have the ability to soak up large quantities of liquids.
