| 20090050839 | METAL OXIDE NANO-COMPOSITE MAGNETIC MATERIAL, FABRICATION METHOD, AND METHOD FOR LINKAGE, ENRICHMENT, AND ISOLATION OF PHOSPHORYLATED SPECIES - The present invention relates to a metal oxide nano-composite magnetic material, fabrication method, and method for linkage, enrichment, and isolation of phosphorylated species. The metal oxide nano-composite magnetic material comprises the magnetic iron oxide nanoparticle, a silica layer immobilized onto the magnetic iron oxide nanoparticle and a metal oxide layer coated onto the silica layer. The magnetic iron oxide nanoparticles can be used for absorbing microwave radiation to accelerate the enrichment and linkage for phosphorylated species onto the metal oxide nano-composite magnetic material. Furthermore, the magnetic property of magnetic iron oxide nanoparticles leads to isolation of the metal oxide nano-composite magnetic material-target species conjugates by simply employing an external magnetic field. The specificity of the metal oxide on the surface of the metal oxide nano-composite magnetic material for phosphorylated species also leads to the linkage/enrichment of phosphorylated species with high selectivity in a short time (extracting time is 30˜90 seconds). | 02-26-2009 |
