Fluorescence study of the fluidity and cooperativity of the phase transitions of zwitterionic and anionic liposomes confined in sol-gel glasses

Article Abstract:

The thermotropic, physical, and dynamical properties of large unilamellar liposomes formed from either 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) or 1,2-dimyristoyl-sn-glycero-3-[phospho-rac-glycerol] (DMPG) encapsulated in sol-gel matrixes are characterized. The results show that the electrostatic interactions between phospholipid polar heads and the porous surface of the host matrix play a vital role for the preservation of the structural integrity of encapsulated bilayer.

Effect of coenzyme [Q.sub.10] incorporation on the characteristics of nanoliposomes

Article Abstract:

The effect of coenzyme [Q.sub.10] (Co[Q.sub.10]) incorporation on the characteristics of nanoliposomes, especially the hydrocarbon chain structures of membrane lipids, is investigated. The results have indicated that Co[Q.sub.10] might intercalate between lipid molecules and perturb the bilayer structure.
