Perspectives of obtaining photosensitizers for near-IR range

摘要

The possibility of using photosensitizers, working in the near-IR range, affords new perspectives on their use in diagnosis and treatment of diseases such as cancer and atherosclerosis. Photosensitizers whose absorption spectrum maximum corresponds to laser wavelengths represent the most interest. The most interesting exploitation of photosensitizers is in the rechannelization of respiratory airways and gullet in the presence of a large malignancy. In this case, the joint action of high-intensity irradiation and possibly PDT can help prevent metastasis. The synthesis and investigation of spectroscopic properties of near-IR-range photosensitizers is of great importance.
