Aqueous dispersion of hydrogel nanoparticles with inverse thermoreversible gelation

摘要

An aqueous dispersion of hydrogel nanoparticles and methods of making the aqueous dispersion of hydrogel nanoparticless having an interpenetrating polymer network (“IPN”) are described. The uniformed sized mono-disperse IPN nanoparticles have inverse thermo gelation properties that allow therapeutic medications to be uniformly distributed in a liquid form of the aqueous dispersion of hydrogel nanoparticles. Such medications can then be released from a solid form of the aqueous dispersion of hydrogel nanoparticles in time dependant manor.
