A study on the structural of phospholipid membranes by thermally stimulated displacement current method

열자격 변위 전류법에 의한 인지질막의 구조 연구

In this study, deposited lipid membranes on the electrode and detected thermally stimulated displacement current generated from it. The researchers examined displacement current of electric conduction organic monolayer generated due to orient change of monolayers alkylchain and changed of dipole moment vertical component due to thermally stimulated. We paid attention to the phase transition temperature obtained by the thermally stimulated displacement current of lipid membrane layers this time. We detected the thermally stimulated displacement current peak of layers. From above results the transition temperature dilauroylphosphatidylcholine layers is about 43.deg. C. This study also compared above results with those obtained by differential thermal analysis method.
