Photon absorption in step-wise multi-photon activation fluorescence (SMPAF) of Sepia melanin
SPIE Proceedings, 2013Previous research has shown that melanin goes through a step-wise three-photon absorption process when the fluorescence is activated with high laser intensity. We have conducted further research using even higher laser intensity for the activation, and have shown the possibility of observing power dependence other than third-order.

At the moment melanins are still enigmatic bio-pigments with structure and determination methods not clearly understood for the international scientific community. Among biopolymers, melanins are unique in many aspects. Some essential biopolymers (proteins, nucleic acids and carbohydrates) are chemically well characterized and can be determined using ...

The melanin-free ink of the cephalopod Sepia officinalis is shown to contain a heat labile proteinaceous component toxic to a variety of cell lines, including PC12 cells. Gel filtration chromatography indicated that the toxic component was concentrated in those fractions eluted at a molecular weight higher than 100 kDa and exhibiting the highest ...

Regulating Sepia melanin agglomerates using tailored kaolinite to accelerate skin wound healing
Colloids and Surfaces B: BiointerfacesUncontrolled hemorrhage and wound healing difficulties are significant challenges in medical care. Wounds that fail to close within a limited time frame are often associated with continuous hemorrhage, hard-to-treat infections, and chronic conditions.

Chemically unaltered melanosomes from black hair were isolated using a mild enzymatic procedure reported by Novellino et al. involving sequential treatment of a homogenized hair sample with different protease enzymes. Time-dependent fluorescence studies show, under identical conditions, that the rate of bleaching upon NH3/H2O2 treatment of hair ...
