摘要: The past five years have witnessed a renewed interest in the field of superparamagnetic composites driven by both excitement understanding individual and cooperative properties at nanoscale potential for use such catalysis, magneto-optics, specially bioscience, where new applications are emerging. basis lies combination nanoparticles with matrixes different nature. Superparamagnetic endow adequate magnetic functionality (guiding, monitoring, heating), while improve stability (sedimentation, shielding), chemical functionality, compatibility (hydrophobicity or hydrophilicity, toxicity,stealth).
