Abstract

The present invention relates to silica magnetic particles having a spherical form and a process for preparing the same. The silica magnetic particles prepared according to the present invention, which are silica particles that includes the magnetic particles and additionally have the functional group on the surfaces, has an advantage that the particle size distribution is uniform. Further, the silica magnetic particles prepared according to the present invention can be used as a reagent for separating biomaterials and a reagent for detecting biomaterials.
