Multiple PDT sessions with chlorin-e6 and LL-37 loaded-nanoemulsion provide limited benefits to periodontitis in rats

Photodiagnosis and Photodynamic Therapy
Background: The combination of photodynamic therapy (PDT) and LL-37 has never been tested in an animal study and our research team background suggests this strategy might be a promising alternative to intensify periodontitis resolution.

Identification of Topical Photosensitizing Agents in Humans

Journal of Investigative Dermatology, 1978
A method is described for the detection of topical photosensitizers in humans. Test agents were applied to the untanned midback under an occlusive dressing for 6 hr and then exposed to broad-spectrum radiation containing UV-A and visible wavelengths from a Xenon arc source. Well-known topical photosensitizers were readily identified.
