A method for preparing macroporous polymethyl methacrylate (PMMA) particles includes the steps of: (a) dissolving a polymethyl methacrylate polymer and Pluronic polymer into an organic solvent (b) introducing the mixed solution of step (a) to an aqueous solution containing a surfactant to carry out emulsion polymerization (c) heating the resultant product of step (b) to allow evaporation of the organic solvent and (d) washing and drying the porous polymethyl methacrylate particles remaining after the evaporation.
