However, melanin was not found to affect StO 2 or the absorption or reduced scattering coefficients at either wavelength. The findings indicate that as melanin levels increase, the accuracy of NIRS ...

Melanin's high refractive index (RI) and broadband absorption capability contribute to the pigment's ability to protect against ultraviolet radiation (UV). These optical properties also contribute to ...

After nearly a century of scientific inquiry, scientists have at last been able to characterize a key component in the substance responsible for giving countless living organisms their color. Despite ...
