a Tumor growth curves of the mice treated with PBS (blank control), PBS + NIR, Pd, Pd + NIR, Pd-Su, and Pd-Su + NIR. The tumor volume was normalized to the initial tumor volume (Day 0). b Mean weight of the tumors harvested from the mice of various groups on the last day. The data were presented as mean ± SD. P values were calculated by two-tailed Student’s t-test (***p < 0.001; ns = no significance). c Photos of the tumors from various groups on the last day. d Histological examination of tumor sections from the mice that received various treatments by the H&E, TUNEL, and Ki 67 staining methods (scale bar, 50 μm).
