10. Conclusion The study successfully demonstrated the synthesis of silver nanoparticles ( AgNPs ) using propolis extract. The synthesized AgNPs showed enhanced stability, as well as notable antioxidant and antibacterial properties. Structural and functional integrity of AgNPs was confirmed using UV-Vis spectroscopy, FT-IR, SEM, and XRD. The results suggest strong potential for biomedical applications of AgNPs synthesized via propolis extract. The method provides a green, eco-friendly approach to developing advanced therapeutic materials with significant biological efficacy.

11. Conclusion XRD Analysis : All peaks matched anatase TiO ₂ Average crystallite size ~22 nm (Scherrer equation) SEM Results : Porous structure similar to pure anatase TiO ₂ Average pore length: 22–25 µm No structural disruption from doping EDX Spectrum : Confirmed presence of Mg, Al, Ti, and O UV-Vis Spectroscopy : No significant change in transmittance or absorption after doping
