 Master’s Thesis Discusses the Effect of Certain Polymers Coated with Different Nanoparticles Derived from Medicinal Plants
The College of Education for Pure Sciences discussed a master’s thesis entitled “Study of the Effect of Certain Polymers Coated with Different Nanoparticles Derived from Medicinal Plants.”
The thesis, presented by researcher Iman Byram in the Department of Physics, focused on the preparation of magnetic iron oxide nanoparticles (Fe₃O₄) using the co-precipitation method, with apricot seed kernel extracts (cold aqueous, hot aqueous, and alcoholic) serving as natural reducing agents. The nanoparticles were then coated with chitosan to improve biostability, and tested against pathogenic bacteria such as Staphylococcus aureus and Escherichia coli.
The results demonstrated that all nanoparticles exhibited significant inhibitory activity; however, the highest antibacterial effectiveness was recorded for the chitosan-coated nanoparticles prepared with the hot aqueous extract. This was attributed to the smaller particle size and enhanced colloidal stability, which facilitated their interaction with the bacterial cell wall.
