摘要：

The effectiveness of the metal oxide nanoparticles viz. CuO and Fe2O3 as antibacterial agents against multidrug resistant biofilm forming bacteria was evaluated. CuO nanoparticles were also experimented for antibiofilm and time kill assay. The CuO displayed maximum antibacterial activity with zone of inhibition of (22 +/- A 1) mm against methicillin resistant Staphylococcus aureus (MRSA) followed by Escherichia coli (18 +/- A 1) mm. The Fe2O3 showed the zone of inhibition against MRSA of (14 +/- A 1) mm followed by E. coli (12 +/- A 1) mm. CuO proved to be more toxic than Fe2O3 nanoparticles showing significantly high antibacterial activity and found to possess dose dependent antibiofilm properties.
