The group of Prof. Dr. Matthias Karg at the Institute of Physical Chemistry at Heinrich Heine University Duesseldorf (HHU) in Germany is creating ultra-thin, highly ordered layers of spherical hydrogel beads that encapsulate gold or silver particles. These structures are of interest for applications in optoelectronics — light-based information and communication technology — and nanophotonics. The researchers have recently published findings on a significant step in the direction of ‘plasmonic nanolasers’ in the journal ACS Applied Materials & Interfaces.
