    Abstract: Provided are organic-inorganic hybrid silica nanoparticles having excellent monodispersity, an organic component (polymer) being introduced into a silica matrix, the whole of each particle being composed of a hybrid between the organic component and an inorganic component [silica], and the particle diameter being in the range of 5 to 100 nm; and a simple and efficient method for producing the silica nanoparticles. Organic-inorganic hybrid silica nanoparticles contain a copolymer (A) composed of an amorphous polyamine chain and a nonionic polymer chain, an acidic group-containing compound (B), and silica (C). A method for producing organic-inorganic hybrid silica nanoparticles includes the steps of allowing a copolymer (A) composed of an amorphous polyamine chain and a nonionic polymer chain to associate with an acidic group-containing compound (B) in a medium and then performing a sol-gel reaction of a silica source using the association product as a reaction field in the presence of water.
