Abstract
The present invention relates to composite particles, coated particles, a method of producing composite particles, a ligand-containing solid phase carrier, and a method of detecting or separating a target substance in a sample. The above described composite particles each contains an organic polymer and inorganic nanoparticles, wherein the content of the inorganic nanoparticles in the composite particles is more than 80% by mass, and wherein the composite particles have a volume average particle size of from 10 to 1,000 nm.
Claims9
A method of producing composite particles, the method comprising:
- mixing a magnetic fluid, a monomer and a polymerization initiator to prepare a monomer mixed liquid so that a content of magnetic nanoparticles is more than 80% by mass with respect to 100% by mass of a material for forming the composite particles in the monomer mixed liquid;
- dispersing the monomer mixed liquid to prepare an emulsion;
- and
- polymerizing the monomer in the emulsion to produce composite particles that comprise magnetic nanoparticles in an amount of more than 80% by mass.
