  • Patent number: 8420055
    Abstract: Amine functionalized magnetic nanoparticle compositions and processes for synthesizing the same are described. The process consists of obtaining a carboxylated polymer in substantially pure form, which is used to prepare a substantially size homogeneous, polymer coated carboxyl, functionalized magnetic nanoparticle. The carboxyl groups are converted to reactive primary amino groups by the use of a water-soluble carbodiimide followed by reaction of a large excess of a diamine. The amine-terminated nanoparticles are then reacted with bifunctional crosslinking agents and with various biomolecules to make nanoparticles for in vitro assays, cell sorting applications and target specific MR contrast agents.
    Type: Grant
