| Due to their unique physicochemical properties, the production and application of nanomaterials have significantly increased across biomedical, environmental, and pharmaceutical fields. Ethanoic extract of Nannorrhops ritchiana was prepared by the maceration method. For the synthesis of zinc nanoparticles, the aqueous extract of Nannorrhops ritchiana is combined with 0.1 M zinc sulfate solution to form zinc nanoparticles. The average diameter of the nanoparticles is measured by X-ray diffraction and scanning electron microscopy (SEM). The antimicrobial activity of the synthesized zinc nanoparticles was assessed against standard bacterial strains using the microdilution method, and the diameter of the inhibitory zone and the minimum inhibitory concentration against the bacterial strains were determined. The results revealed that at a concentration of nanoparticles Nannorrhops ritchiana 1024 µg/mL, the largest inhibition zones were observed against Proteus mirabilis (25 mm) and Streptococcus mutans (15 mm). At 256 µg/mL, no inhibition zone was detected against Streptococcus pyogenes, while Proteus mirabilis showed a 17 mm zone of inhibition, and ethanol extract showed that the largest diameter of the inhibitory zone was at a concentration of 1024 µg/mL against Proteus mirabilis bacteria (10 mm), while the lowest inhibition was against Bacillus cereus and Streptococcus pyogenes bacteria. These findings suggest that zinc nanoparticles synthesized from Nannorrhops ritchiana exhibit strong antibacterial activity against human pathogens, even under particulate matter–contaminated environmental conditions. | ||
