Due to the high degree of resemblance to biological membranes,

lipid vesicles are attracting a great deal of attention as a model

cell membrane system. Since the cellular membrane function is

fundamentally related to its essential constituent, the phospholipid

bilayer (Fig. 2.1), the lipid vesicle studies could provide many

answers related to biological membranes (Fig. 3.1). Vesicles enable

studies to be made of biological membrane structure, self-assembly

properties, phase behaviour, transport, and elasticity properties, as

well as their interactions with ions, macromolecules, or products of
