Carotenoid pigments and photokilling by acridine orange.
It has long been known that certain organic dyes can photosensitize cells, leading to cellular damage or death. Recently, studies were performed on one such dye, Toluidine Blue, to determine the mechanism of its lethal photosensitization of bacteria (M. M. Mathews, J. Bacteriol. 85:322, 1963). These studies showed that the cellular site of the lethal action was the cytoplasmic membrane and its ...
متن کاملCharacterization of Some Orange and Yellow Organic and Fluorescent Pigments by Raman Spectroscopy
Raman spectroscopy has become one of the most important vibrational analytical techniques for the investigation of paint samples and notably for organic pigments. For the analysis of modern materials, especially for synthetic inorganic and organic pigments the prospect of using Raman spectroscopy is an alternative to e.g. Py-GC-MS. It provides enough information allowing for a broad characteriz...
متن کاملAzo pigments and quinacridones induce delayed hypersensitivity in red tattoos.
BACKGROUND Induction of delayed hypersensitivity reactions by red tattoos has been occasionally reported. Little is known about the inks used. Azo pigments have been implicated in some instances, but there is only one reported case involving quinacridones. OBJECTIVES To describe the clinical and pathological features and outcome of skin reactions induced by red tattoo pigments. PATIENTS, MA...
متن کاملAnthocyanins and their variation in red wines. II. Anthocyanin derived pigments and their color evolution.
Originating in the grapes, anthocyanins and their derivatives are the crucial pigments responsible for the red wine color. During wine maturation and aging, the concentration of monomeric anthocyanins declines constantly, while numerous more complex and stable anthocyanin derived pigments are formed, mainly including pyranoanthocyanins, polymeric anthocyanins produced from condensation between ...
