In this study, silver sulfide nanoparticles (Ag₂SNP's) were successfully produced by using fruit extracts of Phyllanthus emblica. UV-vis, FTIR, XRD with SEM and EDX techniques were used for the synthesis process and for characterization of the resulting nanostructures. According to the findings, the fabricated nanostructure had a monoclinic crystal structure, measuring 44 nm in grain size, and its strain was 1.82 × 10^-3. As revealed by SEM analysis, the synthesized nanostructure consists of irregular spherical and triangular shapes. The presence of silver (Ag) and sulfur (S) was also confirmed through EDX spectra. Furthermore, Ag₂S nanoparticles were tested for their ability to effectively inhibit gram-positive and gram-negative bacterial growth. As a result of this study, it was clearly demonstrated that Ag₂S nanoparticles possess powerful antibacterial properties, particularly when it came to inhibiting Escherichia coli growth. Ag₂S nanoparticles had high total H₂O₂ and flavonoid concentrations and the greatest overall antioxidant activity, according to the evaluation of antioxidant activity of the samples. The results obtained from the P. emblica fruit extract were followed by those obtained from Ag₂S nanoparticles were reported in detail. RESEARCH HIGHLIGHTS: Innovative Ag₂SNP synthesis using Phyllanthus emblica fruit extract. SEM with EDX revealed a monoclinic crystal structure with a grain size of 44 nm and a strain of 1.82 × 10^-3. Many of these applications are demonstrated by the potential of Ag₂SNPs to treat and combat bacteria, particularly Escherichia coli. A peak at 653 cm^-1 indicates the presence of primary sulfide aliphatic C-S extension vibrations. The abundant H₂O₂ and NO₂ found in P. emblica nanocomposites make them potent antioxidants.
