ABSTRACT:
The invention relates to spherical and magnetic silicagel particles which are provided with an increased surface by incorporating SiO2colloids and produced by a method for inverse dispersion cross-linking of silica sols. The addition of certain metallic oxides to said silica sols and a subsequent tempering make it possible to obtain silicagel particles which exhibit increased nucleic acid binding properties and are used for separating a nucleic acid and isolating biomolecules.
