Effects of NIR light and CSNPs on cell viability.
(a) NIR light toxicity to cells. Cell viability of MDA-MB-231cells after exposure to 980 nm NIR light (5 mW) in the presence and absence of 10 μg/mL of CSNPs. (b) ARE-Luciferase activity after different periods of NIR light exposure (0, 5, 10 and 30 min) and post-incubation times (24, 48 and 72 h). (c) PDT effect on MDA-MB-231cells. MTT assay of MDA-MB-231 cells incubated with 10 μg/mL of CSNPs for different periods of NIR light exposure (0, 5, 10 and 30 min) and subsequent post-incubation times (24, 48 and 72 h).
