The use of fluorimetry as a non-invasive method for photodynamic diagnosis of intradermal spread of the photosensitizer chlorin E6

photodynamic therapy is a rapidly developing technique for the treatment of oncological, cosmetic, gynecological and other pathologies. The advantage of the method lies in its non-invasiveness, high selectivity and a small number of side reactions. But, most methods for diagnosing the effectiveness of PDT are invasive techniques that require excision of a site of the pathological focus for further research. Therefore, it is necessary to search and study the effectiveness of non-invasive methods of photodynamic diagnostics.
