Iron oxide nano-material: physicochemical traits and in vitro antibacterial propensity against multidrug resistant bacteria

The synthesis of Azadirachta indica leaf extract mediated Iron oxide nanoparticles (FeO-NPs) from ferric chloride were investigated. The characterization results confirmed that FeO-NPs were having good physicochemical traits. The FeO-NPs hold the resistance in ohmic range and coercivity value reached 126emu/g. The FeO-Nps antioxidant efficiency was observed to be 95% of inhibition against 1, 1-diphenyl-2-picrylhydrazyl. The indigo-carmine dye decolourization of 79 and 85% under sunlight and UV-light irradiance were attained for FeO-NPs. The antibacterial and antibiofilm activities of FeO-NPs against bacterial pathogen were tested. The results confirmed that FeO-NPs have a virtuous propensity against gram negative than positive bacteria.
