Macromolecular microparticles and methods of production

(57) They are inside of an aqueous phase, or a polymer microparticle composite formed by carrying out bridge construction combination by a crosslinking agent while heating about the macromolecule which dried the polymer solution of summary water and dried. Dehydrators are a polyvinyl pyrrolidone and a polymer mixing thing of a polyethylene glycol preferably, and a crosslinking agent is glutaraldehyde -- and a macromolecule -- protein -- it is an immunoglobulin most preferably. The directions for research, diagnosis, and medical treatment are also offered.
