Abstract

Hypericin (Hyp) has received attention due to its high phototoxicity against viruses and anti-tumor photoactivity. Using two-photon imaging, we demonstrated that Hyp induced photosensitized modification of collagen fibers in native tissues. Dynamics of photo-processes was monitored by time-lapse multiphoton imaging. We showed that Hyp-mediated processes in collagen tissues may be used for the selective modification of collagen fibers.
