摘要： This invention relates to a unique process for the preparation of polymeric nanoparticles with target molecules bonded to the surface of the particles and having sizes of up to 1000nm, preferably Inm to 400nm, more preferably Inm to 200nm, that are dispersed homogeneously in aqueous solution. To accomplish the above objective, the polymeric nanoparticles of the subject invention are prepared using a novel technique of microemulsion polymerization. The resulting aqueous solution of polymeric nanoparticles is comprised of about 1 to 100 parts per weight of water or buffer, about 1 to 80 parts per weight of polymeric nanoparticles, which the bio-active molecules are conjugated, about 0.001 to 10 parts per weight of emulsifier, and about 0.00001 to 5 parts per weight of radical initiator based on the weight of the solution. In the method of this invention, the target drug/target substance is covalently bonded to the polymeric nanoparticles to secure them from outer intervention in vivo or cell culture in vitro until they are exposed at the target site within the cell.
