A) Relative viabilities of 3T3 and C26 cells after being incubated with various concentrations of P-GNRs for 24 h. B) Hemolytic test on the P-GNRs. The concentration was a) 1.0 mg mL-1, b) 1.5 mg mL-1, c) 3.0 mg mL-1, d) 6.0 mg mL-1, e) 12.0 mg mL-1; sample f was normal saline used as negative control, and sample g was distilled water used as positive control. C) Relative viabilities of C26 tumor cells either not exposed to NIR light or irradiated with NIR light (2.5 W cm-2 for 5 min per treatment, three treatments over 2 h). Data are represented as mean±SE of six wells per group. *P<0.05 by two-sample student's t-test.
