Abstract This study explores the potential antibacterial applications of zinc oxide nanoparticles (ZnO NPs) enhanced with silver (Ag) using plant gel (ZnO-AgO NPs). The problem addressed is increasing prevalence pathogenic bacteria and need for new, effective antimicrobial agents. ZnO NPs possess distinctive physicochemical properties that enable them to selectively target bacterial cells. Their small size high surface area-to-volume ratio allow efficient cellular uptake interaction In this study, average synthesized ZnO-Ag was 77.1 nm, a significant standard deviation 33.7 indicating wide distribution. demonstrated remarkable efficacy against gram-negative gram-positive bacteria, inhibition zones 14.33 mm E. coli 15.66 B. subtilis at concentration 300 µg/ml. Minimum inhibitory concentrations (MIC) were determined be 100 µg/ml 75 S. saprophyticus . Additionally, exhibited excellent biocompatibility, making appropriate various pharmacological uses. utilizes Ferula latisecta gels, offering sustainable eco-friendly approach nanoparticle synthesis. Incorporating Ag into significantly enhances their properties, combined results showing great effects on microbes. findings suggest could promising candidate addressing challenges posed by drug-resistant infections enhancing treatments.

Magnesium (Mg) is an attractive candidate for fracture fixation implants due to its bioabsorbability. However, their mechanical properties under load and in biological environments appear be insufficient, bacterial biofilm formation may further complicate the situation. In this paper, first time, functionalized graphene nanoplatelets (FGNPs) as reinforcement Mg-3Zn-0.5Zr (ZK30) alloy matrix were homogeneously prepared using semi-powder metallurgy (SPM) method, subsequently, composites spark plasma processing (SPS). The compressive strength test was performed different before after immersion simulated body fluid (SBF). ZK30/0.5FGNPs composite shows a significantly higher ultimate (UCS) compared other composites, 285 ± 11 MPa 220 9 exposure SBF environment, ZK30 alloys; which 195 8 135 5 14 days of environment. Furthermore, evaluating antibacterial activity, it proved that adding FGNPs nanofillers could impressively prevent growth colonization Escherichia coli ( E. coli) Staphylococcus aureus S. aureus). Cytotoxicity studies also confirm with low amounts do not show cytotoxic behavior against MG63 cells, while loadings lead toxicity. general, according research results, can used application loaded treatment bone infection.
