摘要：
The terahertz dynamics of water nanodroplets confined in phospholipid reverse micelles have been developed as a probe to explore the interactions of metal ions with lipid membrane interfaces. The terahertz absorption coefficients of reverse micelles vary greatly with different Cu2+ concentrations and with different headgroups. The results proved that the metal ion effects on water dynamics near a membrane surface can be detected via terahertz spectroscopy, thus providing a novel tool for investigating ion-lipid interactions.
