Multiarm star copolymers containing a b-cyclodextrin core and poly(2-ethyl-2-oxazoline) arms (CD-POX) were synthesized and characterized. Synthesized CD-POX star copolymers were able to form supramolecular dendritic polymers (SDPs) in aqueous solutions. The ability of SDPs to encapsulate and transfer small guest molecules and also metal nanoparticles was investigated.
