In the original paper 1 on p. 218, Figure 6E there is error in the fluorescence image of PI and FDA co-staining cells, which arises from confusion of the images. In the revised Figure 6 shown below, the correct fluorescence images are provided. In addition, on p. 219, Figure 8D there is error in the tumors photograph of laser only group, which arises from confusion of the images. In the revised Figure 8 shown below, corrected images are provided by repeating the entire animal experiment. To ensure that the animal experiments are contrasted using the same batch of mice with Figure 8, the corresponding characterizations in Figure S9, S10 and S14 are also included with this correction. These corrections do not alter the major conclusions of this article.

In addition, part of the description was incorrect. In "Animal experiments" (p. 213 right lines 2-10), the correct description should be “4 weeks' old balb/c nude mice (weighing ~ 18 g) were bought from Beijing Vital River Laboratory Animal Technology Co. Ltd. The mice were used under protocols approved by Jilin University Laboratory Animal Center. After one week's feed, 2×106 of KB cells dispersed in 150 μL of cell culture were injected subcutaneously into the right back leg of the mice”. In "Results and Discussion" (p. 216 right line 14), the correct description should be “As exposed under laser irradiation for 0, 3, 8, 10 min”. These corrections do not alter the major conclusions of this article. Besides, for the laboratory animal welfare principle of “3R (Reduction, Replacement, Refinement)”, we shared a blank control group with another work of our group in MRI (Figure 7G-J), which is quoted here 2.
