Thermal imaging of a tumor during photothermal treatment. (a) A thermal image of a tumor-bearing mouse injected with 200 μL of 0.35 mg/mL (3.6 mg/kg) solubilized SWNT solution under 808 nm laser irradiation. The therrmal image was taken 4.5 min into NIR laser irradiation of the tumor and surrounding area at a power of 0.6 W/cm2. Nine mice injected with solubilized SWNTs were thermally imaged while being irradiated, all showing similar results. The temperature rise in the skin surrounding the tumor was below the temperature threshold for tissue damage and no skin damage in the near or long term was observed. (b) A thermal image of a control tumor-bearing mouse without SWNT injection. The therrmal image was taken 4.5 min into 808 nm NIR laser irradiation of the tumor and surrounding area at a power of 0.6 W/cm2. (c) Optical image of the BALB/c mouse in (a) injected with SWNTs, immediately before NIR laser irradiation. (d) Optical image of the mouse in (b) taken immediately before NIR laser irradiation. The arrows point to the subcutaneous tumor in the mouse
