Nanoparticles pigments/colorants

The scheme of the chemical composition of the ceramic ink is visible in Fig. 11. Component A denotes the surface-modified coloring pigments, B the silane oligomers, C the Si02 nanoparticles, and D the silane monomers. 

The third and the only other online TLC-MS approach in carotenoid analysis was presented in the study of the introduction of TiOj nanoparticles on increase of carotenoid production by the extremophilic haloarchea Haloferax mediterranei [7]. The carotenoids were extracted from bacteria and chromatographed on silica gel TLC plates developed by acetone-n-heptane (1 1, v/v). To prevent the diffusion of bands on the developed silica gel TLC plate, the area surrounding the bands was carefully scraped off prior to the addition of MALDI matrix. Based on the high-resolution mass spectra, the four colored pigments were identified as bisanhydrobac-terioruberin, monoanhydrobacterioruberin, 2-isopentenyl-3,4-dehydrorhodopin, and...
