Multifunctional Nanoparticles for Targeted Chemophotothermal Treatment of Cancer Cells

Drug and heat delivery to tumors by active targeting with Herceptin-conjugated doxorubicin-loaded poly(ethylene glycol)–poly(lactic-co-glycolic acid)–Au half-shell nanoparticles (HER-DOX-PLGA-Au H-S NPs) is more effective than passive targeting with their HER-free counterparts (DOX-PLGA-Au H-S NPs). Thus, on NIR irradiation, higher intratumoral temperatures were reached in tumor-bearing mice that were treated with the HER-conjugated particles (see picture).
