Journal of Biophotonics, Volume 19, Issue 1, January 2026.Unmixed maps showing vascular oxygen saturation (sO2), relative collagen, and relative melanin distributions. Maps were extracted from multispectral imaging of B6 and SKH1 Nude mouse abdominal skin using the proposed MS‐LS‐PAM system. ABSTRACT We present a single pump‐source, multispectral laser‐scanning photoacoustic microscopy (MS‐LS‐PAM) platform ...

Transcriptome Comparison Reveals Key Components of Nuptial Plumage Coloration in Crested Ibis
Biomolecules, 2020 Nuptial plumage coloration is critical in the mating choice of the crested ibis. This species has a characteristic nuptial plumage that develops from the application of a black sticky substance, secreted by a patch of skin in the throat and neck region ...

The photoreactive free radical in eumelanin
Science Advances, 2018 We demonstrate experimentally for the first time the presence of two free radicals in the pigment eumelanin. Melanin is the primary photoprotecting pigment in humans as well as being implicated in the development of deadly melanoma.
