Magnetic surface imprinted hydrogel nanoparticles for specific and reversible stabilization of proteins

Abstract

Abstract In this work, we demonstrate the unique capability of surface imprinted hydrogels over magnetic nanoparticles (Fe3O4@MIP-NPs) for protection of enzyme proteins from denaturation induced by heat, UV irradiation, ultrasonication and addition of urea. Moreover, the Fe3O4@MIP-NPs successfully enabled rapid renaturation of heat-denatured proteins under mild conditions. These interesting properties of MIP nanoparticles offer useful tools for protection and renaturation of proteins in various applications.
