FABRICATION AND Some CHaracteristics OF HYBRID NANO PARTICALes Ag-MnFe2O4
Abstract
Hybird nano particles Ag-MnFe2O4 was successfully fabricated by the Seed-growth method and Thermal decomposition method. The shape and size of these nano particles were evaluated by TEM images showing that the particles are quite uniform and have a diameter of about 20 nm. The UV-Vis spectrum of the sample shows that in the wavelength region from 300 ÷ 800 nm, the ferrite manganese nanoparticle does not appear to have an absorption peak, while the spectrum of the silver nanoparticle shows a characteristic surface plasmon resonance (LSPR) peak (with peaks between 400 and 420 nm). Research results show that nano hybrid particles Ag-MnFe2O4 coated with PMAO (MFA10-PMAO) has the ability to inhibit both E. coli - intestinal bacilli and S. areus - Staphylococcus aureus. In which, the antibacterial ability with E. coli is stronger than that of S. Aureus, the antibacterial ring size in both cases are 21.5 and 16 mm, respectively. In addition, MFA10-PMAO nanoparticles also showed easy recovery after treatment, which is favorable for reuse.
