Zinc Oxide Nanoparticle Properties and Antimicrobial Activity

In this study, zinc oxide was prepared by pulsed laser ablation method (PLAL), which is an easy-to-use and inexpensive physical method. The optical properties were studied using UV-Vis spectrometers, structure properties by (XRD) to calculate the crystalline size, and particle size determination by Field emission scanning electron microscopy (FE-SEM) and (EDS), transmission electron microscopy (TEM) assays and it was proved that they are within the ideal nanoscale for biological application. These ZnO NPs were employed on the inhibitory activity of different types of Gram-positive and Gram-negative bacteria, as well as on fungi, and it was noted their ability to penetrate the bacterial cell wall and inhibit its action.

Automated summary

In this study, zinc oxide nanoparticles were synthesized using the pulsed laser ablation method. The nanoparticles exhibited desired optical and structural properties for biological applications, and demonstrated significant inhibitory activity against various types of bacteria and fungi.
