Document Summary

Singlet o2 can be used as a chemotherapeutic agent because of its toxicity to divide cells. Photodynamic therapy use of light for medical treatment. Porphyrins are used for their light absorbing properties. Laser light focused on cells -> porphyrin photosensitizer (absorbs the light energy) > excited photosensitizer -> energy transferred (this causes the energy from triplet oxygen to be transferred to singlet oxygen) Pdt treatment is limited by the delivery of the light, it can easily treat eyes because the eyes can receive the light easily to excite the oxygen cells.
