    摘要： The present invention relates to a perfluorocarbon nanoemulsion containing quantum dot nanoparticles and a method for preparing the same, more specifically, relates to a method for preparing a multifunctional perfluorocarbon nanoemulsion which simultaneously shows the fluorine-based magnetic resonance properties of perfluorocarbon and the optical properties of quantum dot nanoparticles, the method comprising dispersing quantum dot nanoparticles, modified with a fluorine end group, in perfluorocarbon, and then adding an aqueous emulsifier solution containing lipid to the dispersion. The disclosed perfluorocarbon nanoemulsion containing quantum dot nanoparticles has excellent biocompatibility and simultaneously shows optical properties and magnetic resonance properties, and thus can be used as a contrast agent for multi-mode molecular imaging. Accordingly, the nanoemulsion can be used to study cell and small-animal molecular imaging in various fields, including biological and medical fields.

    摘要： The present invention relates to a method for manufacturing uniform size polymeric nanoparticles containing poorly soluble drugs, and more particularly, to a method for manufacturing uniform size polymeric nanoparticles containing poorly soluble drugs, including a first step of dissolving a biodegradable polymer in a non-volatile polar organic solvent, a second step of adding poorly soluble drugs to water and the biodegradable polymer solution to produce a dispersion, and a third step of adding the dispersion to emulsifier solutions in a batch under the condition of low mechanical energy level stirring. The polymeric nanoparticles of the present invention is capable of manufacturing nano-sized small and uniform polymeric nanoparticles through a simple method of employing a non-volatile polar solvent, especially a solvent having a polarity similar to that of water, as a solvent for a mixture solution of biodegradable polymer and poorly soluble materials, and using a low mechanical energy condition and batch-adding of dispersion in an emulsifying process. The polymeric nanoparticles of the present invention are advantageous in that the dissolution rate of the poorly soluble drugs contained in polymeric particles is dramatically improved, and the poorly soluble drugs are gradually and steadily released and maintained at a constant density over a long period of time.
