Chemistry | Most of the photisomerization reactions need photosensitizers, as the reactants R usually possess no optical absorption in the visible range of the spectrum. Source: European Union. (references) |
Health | A drug used in photodynamic therapy. When absorbed by cancer cells and exposed to light, the drug becomes active and kills the cancer cells. (references) |

 | Photodynamic therapy (PDT) is a procedure to treat cancer. Patients are injected with a photosensitizer which is a light sensitive drug selectively retained by cancer cells. When exposed to laser light, the photosensitizer in the cancer cells produces a toxic reaction which destroys the tumor. This photo shows an argon-ion laser, the first component of the argon pumped-dye laser (630nm red). This argon-ion laser emits blue-green light at 488/514 nm, and is used to excite a dye in the second component, the dye laser head, where the wavelength is changed to 630nm red. Different photosensitizers absorb light at different wavelengths. Some absorb light most efficiently in the blue light region of the spectrum around 400 nanometers(nm) with lesser absorption in the green and red light range. However, red light at 630 nm penetrates deeper into the tumor tissue (3-8 mm) than green or blue light. For this reason, the majority of PDT work has used 630 nm light. See artwork: GA-17.

In this therapy, patients are injected with a light-activated drug called a photosensitizer which makes cells in their body sensitive to light. The drug is selectively retained by cancer cells as compared with normal tissue. Doctors then use fiber-optic probes to expose the cancer to laser light. This activates the photosensitizer and produces a toxic reaction that destroys the tumor without irreparably damaging the surrounding normal cells There is a close-up of just the hands.
