The plasmonic photothermal therapy of transplanted tumors in rats using gold nanorods

The study of morphological changes in transplanted liver tumors of rats after plasmonic photothermal therapy (PPTT) was conducted. The gold nanorods (GNs) functionalized with polyethylene glycol were injected by one-, two- and three-step intravenous administration. A day after injection tumors were irradiated by the NIR 808-nm diode laser. The most pronounced damage effect of PPTT was observed after triple intravenous injection of GN.
