DSC and Raman study on the interaction between polychlorinated biphenyls (PCB) and phospholipid liposomes

Polychlorinated biphenyls (PCB) are very toxic lipophilic substances widely used in the past as non flammable dielectric fluids. PCB accumulation in the environment appears to be a great risk for human health. Dipalmitoylphosphatidylcholine (DPPC) and dimyristoylphosphatidylethanolamine (DMPE) liposomes with increasing amounts of Aroclor 1254 have been studied by DSC and Raman spectroscopy. Noticeable changes take place in thermograms and Raman...
