Abstract

The biologically active gel is prepared by bringing together an organic gelling agent, an inorganic compound, a biologically active component or a precursor thereof and a precipitant; as a result of gel precipitation, a biologically active, precipitated gel is formed which contains the biologically active component or its precursor in uniform distribution, the precursor being a substance which, when the gel is used, is converted into the biologically active component. The gel can be precipitated in the form of droplets and can also be dried.
