a Infrared thermal images and b temperature changes at the tumor site under 1064 nm laser irradiation for 2, 4, 6, 8 and 10 min. c The body weight changes and d the relative tumor growth curves in different groups. Data shown as mean ± SD, n = 4 per treatment. Statistical significance was set at *p < 0.05, **p < 0.01. e Digital images of tumors after different treatments and representative mice after treatment with PBS or APCZ + Laser. f Histological H&E and TUNEL staining tumor sections from different treatment groups. Scale bars = 50 and 100 μm, respectively
