An improved method of preparing support matrices for immobilization of reactive chemical entities, such as enzymes, comprises deposition of a polyamine on core support, such as an inorganic oxide, contacting the polyamine-coated core support with a bifunctional reagent which cross-links the polyamine and provides pendant functional groups, and recovering the matrix, wherein the improvement comprises means of depositing the polyamine as a thin, uniform film.
