There is a growing need for engineers to develop effective, powerful, and economical nanocomposites with effective antimicrobial effects. The co-precipitation method was used to fabricate Zinc oxide/Silver nanocomposites (ZnO/Ag NCs). FTIR analysis confirms the presence of a functional group responsible for the stabilization and reduction of fabricated NCs. TEM and SEM analysis showed the internal morphology of the ZnO/Ag NCs as nearly spherical and the average crystallite size of NCs 16.64nm. The NCs are polycrystalline, as demonstrated by the selected area electron diffraction (SAED) pattern. The NCs show good antimicrobial action against Prokaryotic and Eukaryotic organisms. The Minimum inhibitory concentration (MIC) of the NCs are 12.50 and 50µg/mL for E.coli and S. aureus respectively. The finding reveals, ZnO/Ag is found to be an efficient combat agent against prokaryotic and eukaryotic organisms and may be employed as an antimicrobial in the future.
