Solid lipid nanoparticles (SLN) are a type of a carrier system that employs solid lipids as a matrix for drug delivery.1 The drug is molecularly dispersed within the lipid matrix, and the system is stabilized with an emulsifier.2 Nanoparticles distributed within the matrix usually have a mean particle size between 50 and 1000 nanometers.3,4 This reduction in particle size along with drug incorporation throughout the lipid matrix provides relevant pharmaceutical features to SLN as a drug delivery system.
