Magnetic particles having porous surfaces, method of producing the same, carrier for biochemical use, and biotin-bonding particles

摘要

Magnetic particles having porous surfaces are obtained by forming a polymer part (B) soluble in an organic solvent (S) and a polymer part (C) insoluble in the organic solvent (S) on surfaces of magnetic matrix particles (A) and causing the polymer part (B) to come into contact with the organic solvent (S).
