An object of the present invention is to provide a bioabsorbable composite hollow particle in which inorganic particles are adsorbed only on the surface of a hollow particle made of a bioabsorbable polymer, and a method for producing the same. A homogenizer is used for a mixed solution containing a hydrophobic solution in which a bioabsorbable polymer is dissolved in a hydrophobic solvent at a concentration of 5% by weight or more, an inorganic particle, and a hydrophilic solution. After stirring at a speed of 8 m / s or more to form a pickering emulsion, the hydrophobic solvent is removed from the pickering emulsion so that inorganic particles are adsorbed only on the surface of the hollow particles made of a bioabsorbable polymer. Bioabsorbable composite hollow particles can be produced. [Selection figure] None |
