Abstract
Silica-coated magnetic nanoparticles with greater ability to remain dispersed, and methods of making and using silica-coated magnetic nanoparticles. The magnetic nanoparticles comprise a core and a coating, where the core comprises FeOor other magnetic material and the coating has a thickness of from about 1.5 nm to about 2 nm. The magnetic nanoparticles are useful for preparing nucleic acids for analysis, by separating nucleic acids from other components and by normalizing nucleic acid concentrations.
