Targeted medication delivery remains a major challenge in pharmaceutical sciences. Made of solid biodegradable lipids, Solid Lipid Nanoparticles (SLNs) are a potential colloidal carrier system that combines the advantages of polymeric nanoparticles, emulsions, and liposomes while minimizing their disadvantages. SLNs enhance bioavailability, protect labile drugs from degradation, and enable controlled, site-specific administration. This page discusses many preparation methods, including solvent-based processes, high shear homogenization, ultrasonication, microemulsion dilution, and supercritical fluid techniques. Characterization methods such particle size analysis, zeta potential measurement, electron microscopy, atomic force microscopy, and differential scanning calorimetry are highlighted. SLNs are still a developing and important technology in modern drug delivery systems, and they show versatility in a range of administration methods, including parenteral, nasal, pulmonary, ophthalmic, rectal, and topical. Despite some limitations, such as poor drug loading, sophisticated systems like Lipid Drug Conjugates (LDCs) and Nanostructured Lipid Carriers (NLCs) provide useful solutions in addition to their growing uses in gene delivery and cancer treatment.
