Magnetic nanobeadsare a kind of new biomedical functional materials, which have been widely used tothe biological separation, targeted drug, biological sensing, disease diagnosis, tumor hyperthermia, environment monitoring and repair. According to the application problems of the present commercial magnetic nanobeads, we overcame difficult challengesin the preparationand surface modification of magnetic nanomaterials, so theseries of magnetic beads including three categories have successfully developed, which have superior performances, such as smaller particle size, good uniformity, high monodisperse, highmagnetic response, and biological load.Users reflecting, the performanceof the developedmagnetic nanobeadshas reached the international advanced level.We canprovide technical support according to customer's application requirements, we also can joint development of the downstream productions of magnetic nanobeads.
