Desirable Tailoring (image) Institute for Basic Science Caption Hollow polymer nanocapsules (PNs) made of cucurbit-uril (CB) serve as a versatile platform since various metal nanoparticles (NPs) can be introduced on the surface. They allow for a controlled synthesis, prevent self-aggregation, and provide high stability and dispersibility. Pd@CB-PNs show outstanding properties as heterogeneous catalysts in C-C and C-N bond-forming reactions in water.
