Tumor volumes after treatments during 14 days (A) and their digital photographs (B). (A) When tumor volumes reached approximately 0.5 cm3, one group of the mice did not receive any treatment (A, Control group) and two groups of the mice received treatment with conventional Photosan (C, Free PS group) and nanoscale photosensitizer (B, PS-load HSNP group), respectively. The tumor sizes were measured in the following 14 days. Significantly different (P < 0.05) from group A, #Significantly different (P < 0.05) from group C. The digital photograph of the tumor volumes of the three groups before treatment (B) and 14 days after treatment (C). Where, A is the control group; B is PS-load HSNP group and C is the Free PS group.
