Assessment of DNA Damage after Photodynamic Therapy Using a Metallophthalocyanine Photosensitizer

Cell viability expressed as a percentage for the five groups. (a) A549; (b) MCF7; (c) SNO cancer cells. In all three cells types the cells showed a significant decrease in viability after PDT treatment while cells that were pre-sensitized displayed an increase in viability compared to the PDT-treated cells. (***𝑃<0.001; **𝑃<0.005; *𝑃<0.01).
