A process of producing particles for diagnostic reagent, including forming a matrix particle by mixing a nuclear particle having a CV value of 20% or less and a magnetic substance containing at least one of FeOand FeOand giving a shear force to the mixture to adsorb the magnetic substance on the surface of the nuclear particles; and polymerizing a polymerizable monomer in the presence of said matrix particle to form a polymer layer on the magnetic substance layer.

Process for producing particles for diagnostic reagent

A process of producing particles for diagnostic reagent, including a step of polymerizing a polymerizable monomer in the presence of a matrix particle having a magnetic substance layer containing at least one of Fe O and Fe O on the surface thereof and having a mean particle size of 0.4-200 &mgr;m to form a polymer layer on the magnetic substance layer.
