Title:
METHOD FOR PRODUCING MICROPARTICLES
Document Type and Number:
WIPO Patent Application WO/2020/197365
Kind Code:
A3
Abstract:
The present invention relates to a method for producing microparticles. A method for producing microparticles according to an embodiment of the present invention comprises: (a) a step for preparing a porous micro mold (10) and a cover substrate (20), the porous micro mold (10) having a plurality of micro cavities (11) concavely recessed in a predetermined shape and size in one surface thereof; (b) a step for degassing the micro mold (10) in a vacuum chamber (40); a step for taking the degassed micro mold (10) out of the vacuum chamber (40), and placing a microparticle precursor solution (50) between one surface of the micro mold (10) and one surface of the cover substrate (20) so as to fill the microparticle precursor solution (50) inside the micro cavities (11); (d) a step for polymerizing a microparticle precursor in the microparticle precursor solution (50) to synthesize microparticles (60); and (e) a step for recovering the synthesized microparticles (60).
