The in vivo chemo-photothermal therapy. a in vivo infrared thermal images of MCF-7 tumour-bearing mice after intravenous injection of Au@ZIF-8 or PBS buffer activated by 1 W/cm2 808 nm laser for 10 min. b The temperature evaluation profile of tumour site of treated mice under laser irradiation. c The relative body weight of tumour-bearing mice in each group during the treatment periods. d The relative tumour volumes of mice in each group. e The representative photograph of excised tumours from treated mice in each group. Data was represented as mean ± SD (n = 4), *P < 0.05, versus PBS-treated controls
