COATED CHROMIUM DIOXIDE PARTICLES |
摘要 |
TITLE COATED CHROMIUM DIOXIDE PARTICLES Chromium dioxide has favorable magnetic properties which make it desirable as a solid support in heterogeneous immunoassays. However. to be useful in such assays it must be protected against hydrolytic degradation. This invention provides magnetic particles useful in immunoassays having a core of CrO2 which has a reduced surface, the core coated with silica and further coated with a silane. |
