Optimization and characterization of ultrasound assisted preparation of curcumin-loaded solid lipid nanoparticles: Application of central composite design, thermal analysis and X-ray diffraction techniques.

This study is devoted to preparation of novel solid lipid nanoparticles (SLNs) for the encapsulation of curcumin which is produced by micro-emulsion and ultrasonication using stearic acid and tripalmitin as solid lipids, tween80 and span80 as surfactants. The relation between particle size and entrapment efficiency of the produced SLNs was operated by central composite design (CCD) under response likes surface method (RSM). The variables including the ratio of lipids (X
