Nickel Oxide as a Potential Antimicrobial Agent: Synthesis and Characterization

Nickel oxide (NiO) nanoparticles have a natural bactericidal activity that can be further improved by smart doping with other metallic elements. In this work, NiO nanoparticles were prepared by sol-gel method at different concentration to understand their synergistic antimicrobial activity. The successful incorporation of dopants into the NiO lattice and their successful synthesis was confirmed by Fourier Transform Infrared (FTIR) spectroscopy. NiO nanoparticles also showed better performance, thus they hold the promising potential for their applications in the field of medical coatings, disinfectants and as new antibacterial agents used for the fight against drug-resistant microbes.
