Highly biocompatible, hollow coordination polymer nanoparticles as cisplatin carriers for efficient intracellular drug delivery

Highly biocompatible coordination polymer (Prussian Blue) nanoparticles (LC50 > 1000 mu g mL(-1)) with a hollow interior and a microporous framework (denoted as HPB) are utilized as an anticancer drug (i.e. cisplatin) capsule for chemotherapy of bladder cancer T24 cells.
