Syntheses of cross-linked polymeric superparamagnetic beads with tunable properties

A novel, rapid and reproducible method to synthesize functionalized magnetic beads with an original shape is presented. By coating Fe2O3 nanoparticles with PVA, it was possible to tune the size, the number of iron oxide nanoparticles encapsulated and the open porosity of silica beads. Moreover, with PVA pre-modification, functionalized nano-beads were obtained.
