What surfactants are used in SLN?
Could you please elaborate on the surfactants utilized in Solid Lipid Nanoparticles (SLN)? Are there specific types or classes of surfactants that are commonly employed? Are there any advantages or disadvantages to using certain surfactants in the preparation of SLN? Additionally, how do these surfactants contribute to the stability, encapsulation efficiency, and drug release profile of the SLN? Your insights would be greatly appreciated.
