In vivo animal test results. Photographs of the tumors of the mice treated differently 24 h after treatment: (a) neither PSi nor laser treatment (control), (b) PSi treatment only, (c) NIR laser treatment only (NIR laser irradiation 4 times for 2 min at 1.5 W/cm2 each time with a time interval of 2 min), and (d) PSi treatment (PSi concentration = 0.7 g/L) followed by laser treatment (for 20 min at 600 mW/cm2).
