| titleOfInvention | Preparation method of nanosilver and sulfydryl jointly modified magnetic microspheres |
| abstract | The invention belongs to the technical field of magnetic materials and in particular relates to a preparation method of nanosilver and sulfydryl jointly modified magnetic microspheres. The preparation method comprises the following steps of: 1) preparing Fe3O4 magnetic microspheres; 2) preparing SiO2 wrapped Fe3O4 magnetic microspheres; (3) preparing sulfydryl modified SiO2 wrapped Fe3O4 magnetic microspheres; and 4) preparing nanosilver and sulfydryl jointly modified SiO2 wrapped Fe3O4 magnetic microspheres. According to the method, nano Fe3O4 is wrapped by a silane coupling agent and the stability and the acid-base resistance are improved due to the safety and the stability of silica; and a functional sulfydryl group is introduced into the surface through chemical reaction, so that novel modified magnetic nanoparticles are obtained. Due to investment and development of biological technology industry, life science and diagnostic reagent industry, the development of biological magnetic bead products with the technological advantage and the cost performance advantage is greatly promoted. |
