The techniques for photodynamic (PDT) and photo thermal (PTT) disease treatment depend on the utilization of photosensitizers that are gathered in the cancer and lead to growth disposal after light illumination. Endless supply of light of a specific frequency, the photosensitizer changes to an energized state, from which it can return to the ground state either radioactively with fluorescence emanation or non-radioactively with the arrival of nuclear power. Photosensitizers can likewise respond with cell parts through electron move, which prompts the development of free revolutionaries or move energy to oxygen with the arrangement of profoundly receptive singlet oxygen. In this manner, photosensitizers can prompt oxidative weight on a malignant growth cell or perform nearby hyperthermia. The expanded responsiveness of malignant growth cells to warming up to 41-47 °C underlies the viability of photo thermal treatment.
