Drug-loaded nanoparticles allow controlled release and enhanced delivery, yet understanding in vivobehavior has been difficult. Here, the authors develop a platinum prodrug coupled to a polymer platform, and use intravital imaging to show that the nanoparticle accumulates in macrophages, from the which drug redistributes to neighboring tumour cells.
