    摘要: The present invention relates to separation of biomolecules. More closely, the invention relates to a method for production of a separation medium comprising hybrid particles of inorganic and organic material as well as the hybrid particles produced by this method. Finally, the invention relates to use of the hybrid particles for separation of biomolecules, preferably phosphoproteins. The method comprises the following steps: addition of inorganic metal oxide particles to an organic solution to form a mixture; and emulsification of the mixture to form porous hybrid particles, wherein the density of the porous hybrid particles is between 1.0 and 1.5 g/ml, and wherein the inorganic particles have a shape and size that maximizes their active surface area enabling the inorganic particles to interact with biomolecules.
