Abstract
Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) have emerged as promising systems for delivering active ingredients. They are derived from physiological, biodegradable, and biocompatible lipids, offering benefits such as sustained release promotion and increased drug stability. These systems are apt for the efficient transport of therapeutic drugs to target tissues while also providing advantages such as facilitating large-scale industrial production, bioavailability, and protection against degradation. The preparation of these nanoparticles involves utilizing diverse types of lipids, surfactants, and solvents. Common lipid varieties encompass triglycerides, steroids, and fatty acids, selected based on the active ingredient for stabilization within the lipid matrix. Preparation methods can be categorized into high-energy and low-energy approaches. This study investigated the differences between the main methodologies used, comparing SLN and NLC systems, and scrutinizing their respective advantages, disadvantages, and applications.
