| Abstract | ||||
| Silver nanoparticles (AgNPs) have gained significant attention in diverse fields, including medicine, owing to their exceptional antibacterial, antiviral, and anti-inflammatory properties. Given the potential therapeutic uses of AgNPs, this study provides in depth analysis of the impact of silver nanoparticles on the tested Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Pseudomonas aeruginosa. The AgNPs were biologically synthesized by reducing silver nitrate with almond kernels water extract. Surface Plasmon Resonance (SPR) ~435 nm. XRD calculated particle sizes were 18.1 ± 3.5 nm while TEM sizes are 18.2 ± 4 nm for AgNPs.. silver nanoparticles (Ag NPs) exhibited a power full antimicrobial activity against the tested Gram-positive bacteria Staphylococcus aureus with inhibition zone rang (IZ=20.0 mm) and Gram-negative bacteria Pseudomonas aeruginosa (IZ= 23 mm). The obtained results indicate that the silver nanoparticles (Ag NPs) exhibited a powerful antimicrobial activity against the tested Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Pseudomonas aeruginosa which enable us to use this nanoparticle material in contact lenses preservation and packaging. | ||||
