Microparticles formed by mixing a macromolecule with a polymer at a pH near the isoelectric point of the macromolecule and incubating the mixture in the presence of an energy source for a predetermined length of time. The microparticles are composed of homogeneously distributed, intertwined macromolecule and polymer. Each microparticle allows aqueous fluids to enter and allows solubilized macromolecule and polymer to exit the microparticle and may be formulated to provide a sustained release of macromolecule and polymer from the interior of the microparticle when placed in an appropriate aqueous medium, such as under physiological conditions. Methods of production and methods of use for research, diagnostics and therapeutics are provided.
A microparticle comprising a macromolecule and a polymer in an aqueous solution, wherein the concentration of the macromolecule in the microparticle is at least 40% and less than 100% by weight, and wherein the microparticle does not contain any oil.
A method of making microparticles comprising combining a macromolecule and a polymer in an aqueous solution at a pH near the isoelectric point of the macromolecule and exposing the solution to an energy source for a sufficient amount of time to form microparticles.
A microparticle prepared by a method comprising combining a macromolecule with a polymer in an aqueous solution at a pH near the isoelectric point of the macromolecule and exposing the solution to an energy source for a sufficient amount of time to form the microparticle.
A method for delivering a therapeutic agent to a patient comprising administering to the patient a therapeutically effective amount of a microparticle comprising a macromolecule and a polymer in an aqueous solution, wherein the concentration of the macromolecule in the microparticle is at least 40% and less than 100% by weight, wherein the macromolecule comprises a therapeutic agent.
