Abstract
This study employed the chemical reduction (CR) method to synthesize nano-ZnO particles
of varying sizes. Zn(NO₃)₂ functions as a metal precursor whereas NaBH₄ operates
as a reducing agent, creating the fundamental elements necessary for the synthesis
of nano-ZnO particles. The detailed chemical composition of nano-ZnO powders was
examined through Fourier transform infrared spectroscopy (FTIR), X-ray diffraction
(XRD), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM).
The analysis of the nano-ZnO particle encompassed an examination of its composition,
shape, size and crystallinity. The nano-Zn oxide particles were measured at 100
nm and displayed a wurtzite hexagonal structure. The method employed for testing
antibacterial activity against both Gram-positive and Gram-negative bacteria facilitated
the assessment of the antimicrobial properties of the synthesized nano-ZnO particles.
