The potential application of any nanoparticles, including silver nanoparticles (AgNPs), strongly depends on their stability against aggregation. In the current study, an aqueous extract of pomegranate peel was used as a stabilizer during synthesis of AgNPs. Nanoparticles have been prepared by the chemical reduction method from an aqueous solution of silver nitrate in the presence of sodium borohydride as a reducing agent. The AgNPs were characterized by dynamic light scattering (DLS), zeta-potential measurements, UV-Vis spectroscopy and transmission electron microscopy (TEM). The antibacterial efficiency of AgNPs against Escherichia coli was investigated. The size, polydispersity index, FWHM, and colloidal stability of nanoparticles in dispersion depends on the extract concentrations. In the presence of pomegranate peel extract, the nanoparticles suspension shows colloidal stability at least for a week. Our studies show that synthesized AgNPs with the above described procedure were stable at pH = 3-12 and in the temperature range of 25-85 °C. Additionally, AgNPs exhibit antibacterial properties, especially at the lowest amount of extract to silver ratio (K).

Article Synopsis
- The pomegranate peel is rich in phenolic compounds, which have medicinal and commercial value, but their concentrations and biological activities during different ripening stages are not well understood.
- Extracts from pomegranate peels at various growth stages (40, 80, and 120 days) were tested, with stage 2 and stage 3 showing strong antimicrobial effects.
- Notably, the stage 2 extract was most effective against lung, breast, and liver cancer cells, and further analysis confirmed γ-Sitosterol as a key compound responsible for its antimicrobial and cytotoxic properties, although more testing is required to confirm these findings.

Smart innovative nanocomposites based on active ingredients and metallic nanoparticles with effective wound healing and antifungal properties are efficient in overcoming the limitations of traditional therapeutic products. Open wounds provide an ideal niche for colonization by () which poses substantial global health issues owing to delayed wound healing and disordered healing mechanisms. Therefore, proficient innovative therapies that control infection and promote wound healing are of imperative importance for the management of wounds and prevention of infection and possible complications.

The prevalent presence of naphthalene contamination in aquatic ecosystems is a significant concern due to its carcinogenic and priority pollutant properties. This study focuses on the synthesis of magnetized chitosan/alginate/pomegranate peel extract nanocomposites (FeO/PPE/Cs-Alg), was characterized by Zeta potential, vibrating sample magnetometer (VSM), Field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyses. The results predicted that the successfully synthesis of Fe3O4/PPE/Cs-Alg.
