ABSTRACT
In the recent decade, attention of scientists, working in the field of developing new photosensitizers (PS) for photodynamic therapy (PDT) of cancer, has been focused on compounds with intensive absorption in the range of 770 up to 850 nm. The use of PS with this therapeutic window of absorption opens new possibilities for the diagnostics and treatment of malignant neoplasms. The light with these wavelengths scatters weakly and, therefore, can penetrate deeper into the tissue (Scheme 1) [1]. This is of special significance in pigmented tumors, for instance, melanoma. Besides, it is important that accessible and cheap semiconductor lasers can be used for this range.
