摘要
The present invention relates to a method for preparing a capsule nanoparticle used in encapsulating hydrophobic medicines, comprising the following steps: (A) providing a biocompatible polymer and an organic solution containing a hydrophobic medicine; (B) stirring the organic solution at 3-10℃, and titrating with an alcohol solution, so as to make the biocompatible polymer encapsulate hydrophobic medicine to form a capsule nanoparticle; (C) ultrasonic vibrating the capsule nanoparticle at 3-10℃; (D) filtering the capsule nanoparticle to an average size controllable in the range of 60-450 nm; and (E) lyophilizing the encapsulated particles.
