Abstract
Enzyme-occluding polymer particles are produced by a method including the steps of dissolving an enzyme in an aqueous solution of poly(vinyl alcohol) possessing a styrylpyridinium group or a styrylquinolinium group, spray drying the aqueous solution, and exposing the resultant dry particles to an actinic ray, thereby photo-crosslinking the particles.
