Advantages of SLNs over liposomes and polymeric nanoparticles.

Issue Advantages of SLNs over liposomes Advantages of SLNs over polymeric nanoparticles
Avoidance of organic solvents Avoidance of organic solvents when desired Avoidance of organic solvents when desired
Preparation and reproducibility Excellent reproducibility and feasible large-scale production Excellent reproducibility and feasible large-scale production with cost-effective high-pressure homogenization method as the preparation method6
Stability Increased stability of the active ingredient because of the rigid core lipid matrix8 Increased product stability of about 3 years7
Biodegradability Both liposomes and SLNs are biodegradable Lipids of SLNs are physiological and biodegradable, and hence have better biocompatibility and sterilization. On the other hand, polymeric nanoparticles may accumulate undesirably in the liver, spleen etc.9
Binding, entrapment and release SLNs impose greater entrapment efficiency for hydrophobic drugs (since they do not contain an aqueous core with lipid bilayer like liposomes) Drug delivery is extremely site specific for SLNs, whereas polymeric nanoparticles may produce non-specific drug delivery or show unpredictable release towards siRNAs10
Ability to allow controlled release (similar to polymeric nanoparticles) and drug targeting by coating/attaching ligands to SLNs12 11
