Does the size and shape of NiO nanoparticles impact antibacterial activity?

Studies have shown that the size and shape of NiO nanoparticles can have a significant impact on their antibacterial activity. Smaller nanoparticles have been found to exhibit greater antibacterial effects due to their increased surface area, which allows for more efficient interactions with bacterial cells. Additionally, the shape of nanoparticles can also play a role in their antibacterial activity, with certain shapes (such as rods or spheres) showing enhanced efficacy compared to others. Understanding how the size and shape of NiO nanoparticles influence their antibacterial properties is crucial for the development of more effective antimicrobial agents.
