We introduce novel programmable approaches to create ordered multi-component assemblies of optically and magnetically active
nanoscale objects. The methods and concepts developed will be generic and applicable for programmable assembly of nanostructures
for various purposes. One objective is to enhance the magneto-plasmonic effects beyond the best present-day achievements, via protein
cage-based assemblies combining ferromagnetic materials and metals, in two and three dimensions. The use of the protein cages allows
programmable tuning of the magneto-optical response. Another biomolecular template considered in this proposal is native cellulose
nanowhiskers and its supramolecular modifications. We also aim at extending the concept of magnetic plasmons by using novel
materials. The project requires expertise in physics, chemistry, nanoscience, and bio-based materials. It combines optics, magnetism,
self-assembly, soft materials research and advanced scanning probe microscopy.
