Nanoparticles 3-carotene

Kosaraju et al., 2006), as well as to encapsulate probiotic cultures (Fei-joo et al., 1997) and to make vitamin E nanoparticles (100 nm) stabilized by a starch coating suitable for fortified beverages (Chen and Wagner, 2004). And, by using microfluidization followed by solvent evaporation, Tan and Nakajima (2005) have reported preparation of (3-carotene nanodispersions (60-140 nm). 

The importance of carotenoids in photobiology is well known and there is a continuing interest in their photochemistry. Although they do not normally participate in PET processes because of the short lifetimes of their singlet states, incorporation into organized systems with suitable electron acceptors can lead to photoactivity. The dynamics of photoinduced electron injection and recombination between all-trans-8 -apo-p-caroten-8 -oic acid (125) and a Ti02 colloidal nanoparticle have been studied by means of transient absorption spectroscopy. " " An ultrafast ( 360 fs) electron injection from the initially excited S2 state of the carotenoic acid into the Ti02 conduction band with a quantum...

The alumina surface is an extremely versatile and widely used support for studies in many areas of chemistry. To complete the review of the literature in the past two years, Lefondeur et al used EPR to study the paramagnetic properties of nickel nanoparticles deposited on alumina, while Konovalova et al used ID and 2D ESEEM and pulsed ENDOR to study the nature of the adsorbed canthaxanthin and 8 -apo-P-caroten-8 -al radical cations on an activated silica-alumina surface. Both of these excellent and thorough papers describe in detail the interpretations of the EMR data in relation to the role of the surface.
