Fig. 6From: IGF1 receptor-targeted black TiO2 nanoprobes for MRI-guided synergetic photothermal-chemotherapy in drug resistant pancreatic tumora Cytotoxicity of the nanoprobes in MIA PaCa-2 cells. b photothermal-chemotherapy of the nanoprobes in MIA PaCa-2 cells. Concentration of GEM is 3 μg mL−1, and the concentration of Ti is 150 μg mL−1. Data are presented as mean ± standard deviation (n = 3). ns > 0.05, *p < 0.05, **p < 0.01, ***p < 0.001 were evaluated via Student’s t test, and used as the significance thresholdBack to article page
