NOVELTY - The apparatus comprises a chamber as a collecting device, a source material feeding unit, and a unit for depositing a source material such as nanopowder for sputtering such that the nanopowder is vaporized to form nanoparticle. The nanopowder depositing unit comprises a base (200), a unit (600) for forming vacuum in the inner side of the chamber, a unit (700) to supply necessary gas within the chamber to generate plasma that induces the movement of the nano particle cluster to a liquid solvent, and a unit (300) to generate plasma for sputtering the source material target.    USE - The apparatus is useful for manufacturing nanoparticle, which is useful for producing next generation display and solar cell.    ADVANTAGE - The apparatus ensures efficient manufacture of the nano particle with high purity and yield, low surface oxidation, excellent physical properties and dispersibility and uniform-size.    DETAILED DESCRIPTION - The apparatus comprises a chamber as a collecting device, a source material feeding unit, and a unit for depositing a source material such as nanopowder for sputtering such that the nanopowder is vaporized to form nanoparticle. The nanopowder depositing unit comprises a base (200), a unit (600) for forming vacuum in the inner side of the chamber, a unit (700) to supply necessary gas within the chamber to generate plasma that induces the movement of the nano particle cluster to a liquid solvent, a unit (300) arranged inside the chamber to generate plasma for sputtering the source material target, a rotating cylindrical chamber arranged inside the chamber, and a unit filled with the liquid solvent. The base, the plasma forming part, the vacuum formation part and the gas input part rotate together according to the rotation of the collecting device. The source material target is a metal having a diameter of 100 nm to 1 mm or ceramic. The obtained nanopowder has a particle size of 10-100 nm. An INDEPENDENT CLAIM is included for a nano particle manufacturing method.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a nano particle manufacturing apparatus.
