DEVELOPMENT OF MULTİ-MODE PHOTODYNAMİC THERAPY (PDT) LASER AND LED SYSTEMS

Photodynamic Therapy (PDT) is currently being used for treatment in various fields such as cancer, rheumatoid arthritis, dermatological and infectious diseases. PDT uses special compounds such as photosensitizers (PS), light and oxygen for targeted treatment. Successful treatment can be applied when these compounds exist around the desired target.  In PDT cancer treatment; the PS exhibits selective affinity for tumor cells. When it is activated by light, tumor cells are selectively destroyed. In PDT, several light sources are used such as Lasers, halogen, xenon, light-emitting diodes to activate the PS. However, the Lasers have recently been widely used even though the higher costs over the other alternatives. One of the main reasons is that the Laser light can easily be transmitted through the optical fiber. Therefore, it is possible for Laser light can be focused on a very small diameter of tumors with the help of the lenses placed at the end of the fiber optic cable. Laser systems can deliver the exact peak point of the PS activation spectrum. A diode Laser has the advantages of semiconductor technology that produces coherent projection of light in the visible to infrared range. It uses a light beam with a narrow spectrum to target specific wavelength that can lead more successful PDT applications.
