Controllable engineering of asymmetric phosphatidylserine-containing lipid vesicles using calcium cations†
Abstract
A novel method to produce controllable asymmetric lipid vesicles using Ca2+ is reported. The enrichment of negatively charged phosphatidylserine (PS) molecules in the inner leaflet is found not due to charge–charge attraction, but rather a modulation effect on the occupying size of the headgroups of PS molecules.
