摘要: Abstract The PMMA@Co0.5Ni0.5Fe2O4 ferrite containing hybrid nanomaterials with hyamine were prepared using emulsion polymerization method. Structural and morphological properties evaluated XRD, FT-IR, SEM techniques. TGA DTA analysis performed in order to study the thermal of materials contrast reference material. Magnetic studied Quantum Design PPMS (VSM option) a constant external magnetic field equal (100 Oe 1000 Oe) temperature range from 2 380 K. Both pure Co0.5Ni0.5Fe2O4and sample 85% PMMA exhibit superparamagnetic behavior whereas blocking temperatureTB decreases increase content. cytotoxicity assessment J774.E murine macrophages U2OS human osteosarcoma cell lines was performed. Additionally, sensitivity bacteria Escherichia coli ATCC 8739 Staphylococcus aureus 25923 (with/without hyamine) investigated Kirby-Bauer disc
