| titleOfInvention | A kind of preparation method of sulfydryl modification ferroso-ferric oxide/silica magnetic nano particle |
| abstract | The invention discloses a kind of preparation method of sulfydryl modification ferroso-ferric oxide/silica magnetic nano particle, comprise the following steps：1) magnetic ferroferric oxide particle is prepared by solvent-thermal method by raw material of trivalent iron salt；2) using tetraethyl orthosilicate as silicon source, by sol-gal process by the coated with silica of generation on the surface of magnetic ferroferric oxide particle, ferroso-ferric oxide/silica magnetic nano particle is formed；3) ferroso-ferric oxide/silica magnetic nano particle is placed in toluene solution, is uniformly dispersed and obtains solution A；Dimercaptosuccinic acid is added in dimethyl sulphoxide solution, is uniformly dispersed and obtains solution B；Solution A and solution B are mixed into separation of solid and liquid after reaction a period of time, cleaning again, dried, that is, obtains sulfydryl modification ferroso-ferric oxide/silica magnetic nano particle.The magnetic nanoparticle dispersive property of the present invention is good, with good stability and biocompatibility, has potential application value in biomedical sector. |
