Solid Lipid Nanoparticles (SLNs): Advancements in Modification Strategies Toward Drug Delivery Vehicle.

Abstract

Solid lipid nanoparticles are at the cornerstone of the swiftly growing area of medical nanotechnology, having several potential functions in drug delivery, research, clinical care, and a variety of other fields. They provide the opportunity of developing novel therapies due to their unique properties, such as small particle size and being prepared from physiological biodegradable lipids. The loading of bioactive molecules into nanocarriers is a novel drug delivery prototype employed for various drug targeting levels. Hence, SLNs hold a great promise for achieving the aim of targeted and controlled drug delivery. For this reason, they have attracted the extensive attention of scientists and researchers. This review is based on recent studies and research, and here we present advantages, disadvantages, and preparation methods, several advanced modifications, targeting strategies, and recent applications of solid lipid nanocarriers in drug delivery systems.
