Improvement stability and performance of invertase via immobilization on to silanized and polymer brush grafted magnetic nanoparticles.

In this study, magnetic nanoparticles (FeO) were modified sequentially with silica (FeO@SiO), glycidyl methacrylate (GMA) by surface initiated atom transfer radical polymerization (SI-ATRP) and hexamethylene diamine (as a spacer arm). The p(GMA) grafted and SA modified form (i.e.
