Abstract

Objective(s): Antibacterial materials are so significant in the textile industry, water disinfection, medicine, and food packaging. Unfortunately, organic compounds for sterilization show toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. Materials and Methods: Nickel and nickel hydroxide nanoparticles (NiNPs and Ni(OH)2-NPs) were prepared and characterized by DLS, SEM, AFM and ATR. Antibacterial activity assay was carried by Spot on lawn method against two selected standard pathogenic bacteria such as E. coli (as Gram negative), S. aureus (as Gram positive) and multidrug resistance K. pneumonia and E. coli. Also the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined against two selected standard pathogenic bacteria and multidrug resistance K. pneumonia and E. coli. Results: The formation of the NiNPs and Ni(OH)2-NPs were confirmed by DLS, SEM, AFM and ATR. Antibacterial activity of nanoparticles were confirmed against two selected standard pathogenic bacteria such as E. coli and S. aureus. And also, NiNPs and Ni(OH)2-NPs revealed fair antibacterial effect against multidrug resistance K. pneumonia and E. coli based on MIC and MBC data. As well, the experimental data presented that the antibacterial activity of NiNPs was more than Ni(OH)2-NPs. Conclusion: Based on the achieved results, NiNPs and Ni(OH)2-NPs show antibacterial activity against clinical patients bacteria (multidrug resistance K. pneumonia and E. coli(. Finally, the NPs evaluated in this study have promising properties for applications as antiseptic agent for environment; however, further studies are warranted such as study toxicity NPs on normal human cell line and other clinical bacteria.
