Oh KS, Han SK, Lee HS, Koo HM, Kim RS, Lee KE, Han SS, Cho SH, Yuk SH: Core/Shell nanoparticles with lecithin lipid cores for protein delivery. Biomacromolecules. 2006 Aug;7(8):2362-7.
Core/shell nanoparticles with lipid core, were prepared and characterized as a sustained delivery system for protein. The lipid core is composed of protein-loaded lecithin and the polymeric shell is composed of Pluronics (poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide) triblock copolymer, F-127). Based on the preparation method in the previous report by us, the freeze-drying of protein-loaded lecithin was performed in the F-127 aqueous solution containing trehalose used as a cryoprotectant to form stabilized core/shell nanoparticles. Cryo-TEM (transmittance electron microscopy) and a particle size analyzer were used to observe the formation of stabilized core/shell nanoparticles. For the application of core/shell nanoparticles as a protein drug carrier, lysozyme and vascular endothelial growth factor (VEGF) were loaded into the core/shell nanoparticles by electrostatic interaction, and the drug release pattern was observed by manipulating the polymeric shell. |
