▎ 摘  要

NOVELTY - A graphene-magnetic chitosan polymer as a nano probe of detecting pathogenic bacterium is disclosed. The graphene-magnetic chitosan polymer is manufactured by a method comprising: providing a graphene-chitosan polymer, providing a magnetic chitosan polymer, mixing the graphene-chitosan polymer and the magnetic chitosan polymer to form a mixture, wherein the mixture carries out a reaction under room temperature for 2 hours to obtain the graphene-magnetic chitosan polymer. The graphene-chitosan polymer is obtained by dissolving graphene into deionized water, followed by adding a first chitosan-acetic acid solution. The magnetic chitosan polymer is provided by mixing a mixture of ferrous chloride and ferric chloride with ammonia to form a magnetic nanoparticle, followed by mixing the magnetic nanoparticle with a second chitosan-acetic acid solution to immobilize chitosan on surfaces of the magnetic nanoparticle.
