METAL PARTICLE, MAGNETIC BEAD FOR BIOLOGICAL SUBSTANCE EXTRACTION, AND THEIR PRODUCTION METHODS |
摘要 |
<p>Fine metal particles each comprising a magnetic metal core particle and two or more coating layers, the outermost layer among the two or more coating layers containing an oxide of silicon and aluminum at an Al/Si atomic ratio of 0.01-0.2, and a method for producing fine metal particles comprising the steps of coating each primary particle comprising a magnetic metal core particle and a first coating layer with a mixture of silicon alkoxide and aluminum alkoxide, and then hydrolyzing the silicon alkoxide and the aluminum alkoxide, thereby forming a coating layer comprising an oxide of silicon and aluminum.</p> |
