A bisphosphonic amphiphilic molecule (BPA) forms a reverse bilayer vesicle in THF. When added a small amount of water, it is trapped inside the core as bound water and de-stabilizes the bilayer. Once the amount of water exceeds the capacity of the bound water sites, the reverse vesicle is transformed into a reverse micelle.
