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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
