Description

technical field [0001] The invention relates to the technical field of nano biomedical materials, in particular to a production system and a production method of nano biomedical materials. Background technique [0002] In recent years, with the emergence of nanotechnology, nano-biomedical materials have emerged as the times require. Nano-biomedical materials have become important research objects in the field of biomedical due to their unique biocompatibility, good degradation performance, and high targeting. . However, the current lack of industrialized production systems and production methods for nano-biomedical materials leads to high production costs of nano-biomedical materials, and the existing production systems are more complicated due to production methods and involve more equipment. Biomedical materials are easily contaminated, which leads to lower purity, which affects their medical effects. Contents of the invention [0003] In view of this, the present inve...
