This thesis developed antibacterial nanobiocomposites based on biodegradable polymers for potential food packaging applications. Phyllosilicates were incorporated to enhance the mechanical, thermal, and barrier properties of the polymers, while AgNPs provided antibacterial activity.

The work also investigated the optimization and stability of biogenic AgNPs synthesized using rosemary extract. These AgNPs showed strong antibacterial activity at non-cytotoxic concentrations, with stabilization further enhancing their antibacterial performance without cytotoxicity toward mammalian fibroblasts.

The developed materials and AgNPs were characterized using complementary techniques, including TGA, TEM, SEM, DLS, FTIR, XRD, UV-Vis spectroscopy, and SEC, to evaluate their structural, morphological, thermal, and physicochemical properties.
