Development of nanoplatforms with in situ activation for chemotherapy represents a promising modality biomedical application. Herein, multifunctional nanoplatform, CMS@DTC@PDA@RuNO@FA (abbreviated as CDPNF NPs), was developed highly efficient antitumor therapy, which diethyldithiocarbamate (DTC)-loaded mesoporous Cu2MoS4 (CMS) nanoparticles were covered by polydopamine (PDA) layers and further covalently modified NO donor (RuNO) folic acid (FA)-directing moiety. Under the mild acidic tumor microenvironment (TME), NPs co-liberated DTC Cu2+ site, where formation cytotoxic Cu(DTC)2 complex effectively killed cells. Furthermore, under near-infrared (NIR) light irradiation, could deliver nitric oxide (NO) produce superoxide anions (O2•-), followed more toxic peroxynitrite (ONOO-), led to promoted cell apoptosis. 1064 nm NIR vivo experiments demonstrated an impressively high inhibition rate (∼97%) while good biocompatibility. This work activated approach precision medicine that might imply its potential clinical applications.
