Water in Confinement

Abstract
Reverse micelles--isolated, surfactant-coated water droplets--are useful model systems for confined water in biology and materials science. In her Perspective, Levinger reviews recent advances in the study of reverse micelles, which have shown that the properties of confined water differ substantially from those of bulk water. The collective motion of the water molecules is shown to depend strongly on the confinement in the reverse micelles. Such effects are also likely to occur in cells and porous materials and may be exploited in nanometer-scale synthesis.
