Abstract

Magnetic microgels—obtained by encapsulation of magnetic nanoparticles into polymers acting as clustering agents—represent good candidates for biomedical applications and high gradient magnetic separation process because they fulfill important requirements, such as: superparamagnetic behavior, high saturation magnetization, and rich in surface functional groups. Biocompatible magnetic microgels were obtained using high colloidal stability magnetic nanofluids as primary materials in various synthesis procedures that allow encapsulation of clusters of magnetite nanoparticles into different polymers including polyacrylic acid, poly(N-isopropylacrylamide), poly(3-acrylamidopropyl trimethylammonium chloride). Our results show that polymer encapsulation of magnetite nanoparticles from magnetic nanofluid allows for the tailoring of the magnetic microgels’ properties by controlling the synthesis parameters.
