In this chapter, the structural dynamics and properties of liposomes, composed of amphiphilic lipid molecules with liquid crystal-like features, are examined.
The self-assembly of lipids into aggregates such as micelles and bilayers is driven by
weak non-covalent interactions, including hydrophobic forces. Factors such as temperature, pH, and lipid concentration influence the size and shape of these aggregates,
while the packing parameter provides insights into the geometry of lipid structures.
The chapter also discusses lipid bilayer permeability, highlighting the effects of temperature and hydrophobicity on the movement of molecules like ions, water, and nonpolar
gases. Investigating packing constraints and permeability mechanisms is critical for
advancing knowledge of liposome behavior, particularly in biomedical applications.
Keywords: Amphiphilic lipids, self-assembly, packing parameter, bilayer structure, permeability, drug delivery, lipid dynamics.
