(A) The relative cell viability of HCT116 cells performed by MTT assay under 808 nm photoirradiation for 5 min (1 W/cm2) following incubation with QuCy7@mPEG NPs (0–3.0 mg/mL) for 24 h. Data are presented as means ± SD (n = 3), *p < 0.05, or **p < 0.01 based on Student’s t-test. (B) Fluorescent images of LIVE/DEAD co-staining assays of HCT116 cells after treatment with QuCy7@mPEG NPs (0, 0.5, and 1.0 mg/mL) for 24 h before irradiating for 5 min.
