Beyond chemotherapeutics: cisplatin as a temporary buckle to fabricate drug-loaded nanogels

A cisplatin templated nanogel with targeting capability was synthesized, inspired by cisplatin as a chemotherapeutic drug. After crosslinking the natural polysaccharide hyaluronan, a ligand for CD44, cisplatin could be removed by simple dialysis in a salt solution while the withheld drug remains entrapped.
