Abstract
The invention relates to a method for the preparation of discrete particles containing a biologically active substance comprising discrete particles of support material having immobilized in the pores thereof a biologically active substance (e.g. an enzyme). The method includes precipitating a biologically active substance in the pores of the particles of support material, by use of a precipitating agent comprising or including a water miscible organic liquid, and treating the biologically active substance precipitated in the pores to cause cross-linking so as to immobilize biologically active substance in the pores of the particles or porous support material.
