Solid Lipid Nanoparticles: Method, Characterization, and Applications

Solid lipid nanoparticles (SLN) were highlighted as a promising next-generation drug delivery system with potential applications across pharmaceuticals, cosmetics, and clinical medicine. These nanoparticles served as colloidal carriers for both hydrophilic and lipophilic drugs, offering alternative administration routes such as oral, nasal, and pulmonary. The review emphasized SLN's ability to incorporate proteins and antigens for therapeutic purposes, potentially overcoming challenges associated with conventional chemotherapy. The document discussed the advantages, production methods, characterization, and applications of SLN, suggesting that further investigation could lead to new therapeutic approaches for complex diseases.
