Patent number: 6255477Abstract: Magnetic glass particles are prepared containing a magnetic core coated with a glass layer having a substantially pore-free glass surface. The particles are used for separating biological material such as nucleic acids. A preferred process of preparing the particles is by forming a mixture of magnetic cores with a sol formed from an alcohol and a metal alkoxide, spray-drying the mixture to coat the cores with a layer of gelled sol, and heating the coated cores to obtain the magnetic glass particles. Preferably, the particles have an average particle size of less than 100 &mgr;m and any pores of the glass surface have a diameter of less than 10 nm. The magnetic core may be a composite material containing a mica core and magnetite particles immobilized on the mica core, and the glass layer may contain boron oxide. Magnetic core materials include magnetite (Fe3O4) and Fe2O3.Type: GrantFiled: March 11, 1998Date of Patent: July 3, 2001Assignee: Roche Diagnostics GmbHInventors: Jörg Kleiber, Thomas Walter, Herbert Harttig, Christoph Lesniak, Martin Mennig, Michael Riedling, Helmut Schmidt
