  • Publication number: 20220226512
    Abstract: Composite particles, each of which is obtained by forming, on the surface of a gadolinium oxide-containing particle, a cover film that contains a polymer obtained by polymerizing a monomer component containing a monomer having an ethylenically unsaturated bond; a macrophage imaging agent which contains the composite particles; and a method for producing composite particles, wherein a monomer component containing a monomer having an ethylenically unsaturated bond and gadolinium oxide-containing particles are mixed with each other, and after emulsifying the thus-obtained monomer component-containing mixture in water in the presence of a surfactant and a polymerization initiator in water, the monomer component is polymerized, thereby forming cover films on the surfaces of the gadolinium oxide-containing particles.
