We report a one-pot synthesis of poly(diallyldimethylammonium chloride)-coated Fe3O4 (PDDA-Fe3O4) nanoparticles (NPs) by the coprecipitation method. The formed PDDA-Fe3O4 NPs were characterized by powder X-ray diffraction and superconducting quantum interference device. The crystalline structure and superparamagnetic property of PDDA-Fe3O4 NPs were found to be similar to those of Fe3O4 NPs, indicating that the presence of PDDA does not affect the formation of Fe3O4 NPs. Moreover, glucose… CONTINUE READING
