  • glycol) linker, which served as a spacer unit between the polymer and the bioactive cRGD domain [15]. As the final coupling strategy, we chose the Huisgen-type azide–alkyne-“click”-chemistry for which connecting elements 5 and 6 were coupled to polymer derivative 4. Classically, copper catalysts are
