  • Porous ferro-or ferrimagnetic glass particles for isolating molecules
    Patent number: 8202427
    Abstract: Porous, ferro- or ferrimagnetic, glass particles are described that selectively bind molecules of interest, especially nucleic acid molecules; under appropriate conditions. Methods of preparing the porous, ferro- or ferrimagnetic, glass particles and their use for identifying or separating molecules of interest are also described. Kits comprising the porous, ferro- or ferrimagnetic, glass particles are also provided.
