Cytotoxicity of LIPC in CT26 cells under 808 nm laser. A Cell viability of CT26 cells treated with LIC, LI, and free ICG for 18 h, 808 nm laser irradiation (0.5 W/cm2, 5 min) and cultrured for another 6 h, and B with LPC, LP, and free PTX-BSA for 24 h. C Cell viability of CT26 cells with various treatments. The concentration of ICG, PTX-BSA, and CCM were 1.2, 0.6, and 2.5 µg/mL, respectively. D, E ROS generation in CT26 cells with various treatments. Scale bar: 20 µm
