A REVIEW ON "Solid Lipid Nanoparticles" (SLNs)

Solid lipid nanoparticles (SLNs) were recently developed in 1991 having particle size range from 10 to 1000 nm. SLNs used for novel drug delivery system basically it is colloidal carrier of lipids. In this review proposed of ideal characteristics of SLNs, Advantages & disadvantages of SLNs. This review also discussed the preparation methods of SLNs with diagrammatic representation procedure. Appropriate determination of characterization of SLNs like zeta potential and particle size, SEM, differential scanning Calorimetry and powder x-ray diffraction, etc. Route of administration of SLNs are also discussed in this review. Also added the various applications of SLNs in the advance drug delivery with suitable example.
