A drug-delivering nanoparticle with cisplatin core (green) is formed by polymerization of doxorubicin- and camptothecin-derivatized monomers and a cisplatin cross-linker.
The first polymer nanoparticles that carry a defined ratio of three cancer drugs and release them with three independent triggering mechanisms have been developed. The approach could provide a new way of delivering specific amounts of multiple drugs to patients and could help researchers optimize doses of such combination therapies.
The drug delivery nanoparticles were developed by Jeremiah A. Johnson of MIT and coworkers (J. Am. Chem. Soc. 2014, DOI: 10.1021/ja502011g).
