Fig. 6. (a) Intracellular ROS generation of FeND incubated with A549 cells and exposed to 808 nm laser in normoxic and hypoxic tumour environments. (b) Cell viability of A549 cells treated with different concentrations of FeND and exposed to 808 nm laser in normoxic and hypoxic cellular environment. Statistical relevance was assessed as mentioned in Section 2.5.6. The bar represents mean ± SD. Significant difference between untreated and treated samples is indicated by *p < 0.05, *p < 0.01, ***p < 0.001.
