STRUCTURE AND PROPERTIES OF IMB |

| Abstract: | The influence of structure and properties of immunomagnetic beas(IMB) on application of IMB in bio engineering field was studied. The super para magnetic ultra fine magnetic powders was prepared. The ultra fine powers improved the surface properties and achieved the hybridization between the ultra fine powers and the organic monomer molecular. The IMBS of various diameters, which had discribution in the narrow range were obtained. The IMB consists of the core contained ultra fine magnetic powders, high molecular materials layer and the chemical functional groups layer. The IMB has super paramagnetic, absorptive capacity to protein and superior acid and alkali resisting properties. The IMB may be applied in cells separation, immunoassays, bio active substances separation and molecular biology field. |
