  • Method for producing porous particle
    Patent number: 9987228
    Abstract: A method for producing porous particles includes (1) a step of preparing a solution of an amphiphilic substance by dissolving the amphiphilic substance in a mixed solvent capable of being freeze-dried, (2) a step of producing a precipitate containing the amphiphilic substance by cooling the solution obtained in step (1) to a temperature equal to or less than a phase separation temperature of the solution, and thereafter holding the solution at the temperature, and (3) a step of producing porous particles by freeze-drying the solution containing the precipitate obtained in the step (2).
