| titleOfInvention | Method and apparatus for manufacturing polymer microspheres |
| abstract | The present invention relates to a method and apparatus for manufacturing a polymer microsphere, comprising: spraying a biocompatible water-soluble polymer solution at a constant pressure through a nozzle to form droplets; Contacting the formed droplets with a liquefied gas to form frozen particles; And removing the liquefied gas and lyophilizing the frozen particles to prepare a polymer microsphere. The present invention is characterized in that it is carried out at low temperature using a water-soluble polymer that is soluble in water, without using an organic solvent. |
