Platinum-crosslinking polymeric nanoparticle for synergetic chemoradiotherapy of nasopharyngeal carcinoma

Despite extensive use of radiotherapy in nasopharyngeal carcinoma (NPC) treatment because of its high radiosensitivity, there have been huge challenges in further improving therapeutic effect, meanwhile obviously reducing radiation damage. To this end, synergistic chemoradiotherapy has emerged as a potential strategy for highly effective NPC therapy. Here, we developed RGD-targeted platinum-based nanoparticles (RGD-PtNPs, denoted as RPNs) to achieve targeted chemoradiotherapy for NPC. Such nanoparticles consist of an RGD-conjugated shell and a
