Abstract
A method for producing magnetic particles includes forming a hydrophobic first polymer layer on the surface of a mother particle containing superparamagnetic particles, forming a second polymer layer having glycidyl groups at least on its surface on the first polymer layer, and introducing a polar group containing one or more of at least one atom selected from the group consisting of an oxygen atom, a nitrogen atom, and a sulfur atom by chemically modifying the glycidyl groups.
