IR780 embedded within the nanoparticles is used as the photothermal agent, which could also be applied in vivo fluorescence imaging of 4T1 tumor-bearing mice at 12, 24, 48, 72, 96, and 120 h after intravenous injection of (a) bare core INPs and (b) PLTM-INPs lied in NIR fluorescence imaging. c Comparison of representative in vivo IR of mice bearing MCF-7 tumor injected with different components after laser irradiation for 5 min. d magnetic resonance imaging contrast after all kinds of nanoparticles injected with the same amount. Red arrows indicated the sites of MCF-7 tumors in mice. e After PTT treatment with different kinds of nanoparticles, the highest tumor temperature in treated mice increased. White circles indicate the tumor sites. Reprinted with permission from Refs [32, 103]
