Studying the in vitro behaviour of cationic solid lipid nanoparticles as a nonviral vector

SLNs are basically composed of a solid lipid core in nanometer ranges stabilized by a layer of emulsifier; they can be prepared by using lipids with a relatively high melting point (i.e., triglycerides, hard fat types, partial glycerides, steroids and waxes). Among these lipids, glycerides, which are composed of fatty acids, can be employed in injection form since they are already used in parenteral nutrition
