▎ 摘　　要

NOVELTY - Producing graphene oxide porous magnetic particles, comprises (a) dispersing magnetic particles and graphene oxide in distilled water respectively, (b) mixing magnetic particles dispersion solution and graphene oxide dispersion solution, and adjusting pH of the mixed solution, (c) separating and washing the obtained gel-form reactant product, and (d) drying and heat treating the washed product. USE - The method is useful for producing graphene oxide porous magnetic particles (claimed). ADVANTAGE - The method improves recovery efficiency of particles. The particles improve inherent functions through immobilization and stabilization of enzyme, protein, drug and functional bio-molecule using porous structure in bio-industries.
