Abstract
The present invention provides a method for producing microparticles in which a porous micromold is degassed such that a precursor solution is quickly loaded into the micromold through the suction force of the micromold regardless of the viscosity and wettability of the precursor solution.
Claims13
A method for producing microparticles comprising (a) preparing a porous micromold having a plurality of recessed microcavities with a predetermined shape and size on one surface thereof and preparing a cover substrate, (b) degassing the micromold in a vacuum chamber, (c) taking the degassed micromold out of the vacuum chamber, arranging a microparticle precursor solution between the one surface of the micromold and one surface of the cover substrate, and filling the microparticle precursor solution in the microcavities, (d) polymerizing the microparticle precursor in the microparticle precursor solution to synthesize microparticles, and (e) recovering the microparticles.
