Audio to microwave frequency dielectric study of the pretransition region in DPL-water systems

The phospholipid-water mixtures are used as model systems to investigate the structure and function of biological membranes. The dielectric behaviour of DPPC-water and DPPE-water systems was explored at audio (≥ 2kHz) and microwave (10 GHz) frequencies versus temperature. Particular care was devoted...

Zusammenfassung:The phospholipid-water mixtures are used as model systems to investigate the structure and function of biological membranes. The dielectric behaviour of DPPC-water and DPPE-water systems was explored at audio (≥ 2kHz) and microwave (10 GHz) frequencies versus temperature. Particular care was devoted to the pretransition below the main gel-liquid-crystalline phase transition. A possible interpretation of the pretransition mechanism is given in terms of capillary waves.
