- Biocompatibility and Biodegradability: SLNs are made from lipids that are generally recognized as safe (GRAS) by regulatory authorities. - Controlled Release: SLNs can provide sustained and controlled release of active pharmaceutical ingredients (APIs). - Protection of Drugs: Encapsulation in SLNs can protect drugs from degradation due to environmental factors. - Improved Bioavailability: SLNs can enhance the bioavailability of poorly water-soluble drugs.
