제목 Preparation and Characterization of Doxorubicin Loaded Core/Shell Nanoparticles for Anti-Cancer Drug Delivery.
초록 Doxorubicin loaded core/shell nanoparticles were prepared and characterized as a drug delivery system. The lipid core is composed of lecithin and polymeric shell is composed of Pluronic (poly(ethylene oxide)-poly(propylene oxide)- poly(ethylene oxide) triblock copolymer, F-68). The freeze-drying of doxorubicin loaded lipid core was performed in the F-68 aqueous solution containing trehalose used as a cryoprotectant to form stabilized core/shell nanoparticles. FE-SEM (field emission-scanning electron microscopy) was used to observe the morphology of core/shell nanoparticles and electrophoretic light scattering was used to observe the particle size and zeta potential. doxorubicin was loaded into the core/shell nanoparticles by electrostatic interaction. As a result of release pattern, the core/shell nanoparticles show the sustained release of loaded drug. The core/shell nanoparticles in this study can be utilized as a drug delivery system for anti-cancer drug.
