Betalains in some species of the amaranthaceae family: A review [PDF]
, 2018 Natural pigments are largely distributed in the plant kingdom. They belong to diverse groups, with distinct biochemical pathways. Betalains with colours that range from yellow to red-violet can de divided into two main subgroups: betaxanthins and ...

Identification of Novel Pigmentation Modulators by Chemical Genetic Screening [PDF]
Journal of Investigative Dermatology, 2007 There is a continual need for compounds that effectively modulate melanin synthesis. To identify novel pigmentation modulators and their cellular targets, chemical genetic screenings were performed with triazine-based combinatorial libraries that include various linkers as intrinsic components of the small molecules in the library.

The Application of Cathodoluminescence (CL) for the Characterization of Blue Pigments
HeritageThe combined application of Cathodoluminescence (CL) with Scanning Electron Microscopy (SEM) on paintings and painted surfaces has the potential to identify both organic and inorganic pigments on a micrometre or even nanometre scale.
