    • PROBLEM TO BE SOLVED: To provide a method for producing mesoporous silica nanoparticles by which particle diameter and mesopore size are more easily controlled than by a conventional method and spherical, monodisperse and highly homogeneous mesoporous silica nanoparticles are easily obtained.
      SOLUTION: The method for producing mesoporous silica nanoparticles includes: (1) a step 1 where in an emulsion solution containing a surfactant, water and a hydrophobic solvent, the following step A and step B are carried out simultaneously or sequentially to obtain polymer-silica composite particles which are composite particles of polymer particles and silica particles; step A: a step of forming polymer particles by adding a monomer and a polymerization initiator, step B: a step of forming silica particles by adding a silica source which produces a silanol compound upon hydrolysis and a basic catalyst and bringing the silanol compound into hydrolysis-dehydration condensation; and (2) a step 2 of removing the organic component from the polymer-silica composite particles.
