Hydrogels are expected to have important applications as biomaterials , while the dispersion of nanoparticles in such polymeric matrices can provide optical or electrical properties. Here is described the inclusion of Fe 2 O 3 nanoparticles in several hydrogels. Analysis of the resulting magnetic polyacrylamide gels includes their ability to swell in aqueous solution (the Figure shows such a gel before and after swelling).
