摘要：
A method for manufacturing resin particles is provided. The method includes the steps of: dissolving a resin free of poly(lactic-co-glycolic acid) (PLGA) in a good solvent of the resin to prepare a resin solution; and discharging the resin solution from at least one discharge hole having an inner diameter of less than 1,000 μm into a poor solvent of the resin to form resin particles.
