well-dispersed goldnanoparticles as cross-linking agents in nanocompositehydrogel formation was studied. Maleimide-coated goldnanoparticles were synthesized and used for Diels–Alder cycloaddition with furan modified gelatin. Hydrogel formation was aided by additional amide coupling of the modified gelatin with chondroitin sulfate. The cross-linking ability of the functionalizednanoparticles was evaluated

Weakly protected metal nanoparticles (MNPs) are used as precursors for the preparation of catenane- and pseudorotaxane-decorated NPs of various compositions (gold, palladium, platinum). When attached to the surface of MNPs, the molecular switches retain their switching abilities. The redox potentials of these switches depend on and can be regulated by the composition of the mixed self-assembled monotayers covering the MNPs.
