Abstract
Glass microbeads bearing a coating which includes at least one binding agent fixed to the glass microbeads, and which binding agent is adapted releasably to bind to a material contained within a fluid medium by a biological affinity reaction, whereby the material can be removed from the fluid medium with the glass microbeads and then stripped from the glass microbeads while leaving the at least one binding agent attached to the glass microbeads. Inventive microbeads may bear a monomolecular layer of a silane as a fixing agent for a binding agent which is selected for its biological affinity for the material to be separated.
