▎ 摘　　要

NOVELTY - A magnetic graphene oxide-nano silver composite material comprises a magnetic graphene oxide as a carrier, polyethyleneimine as a reducing agent and a stabilizer, and silver nanoparticles formed and fixed in-situ on surface of the magnetic graphene oxide. The magnetic graphene oxide is obtained by subjecting graphene oxide and an amino group-containing magnetite to covalent reaction. USE - Magnetic graphene oxide-nano silver composite material is used as hydrophilic stationary phase in enrichment of glycopeptide (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of magnetic graphene oxide-nano silver composite material.
