The fluorescent images of live/dead cell assay (A–C) after NIR
irradiation and the cytotoxicity of DOX@GoMe coupled with NIR
irradiation (D). Cells in A, B, and C were treated with blank medium, blank
GoMe, and GoMe coupled with NIR irradiation, respectively. The laser dose was 10
min, 2.83 W/cm2. Scale bars in A–C are 50 μm. Data
were presented as mean ± SD, n=3, P < 0.05 *; P
< 0.01 #).
