The master's thesis defense of (Rusel Jaafar Dahi) in the Department of Physiology and Medical Physics at Al-Nahrain College of Medicine.

On Wednesday, December 18, 2024, the master's thesis defense of (Rusel Jaafar Dahi) in the Department of Physiology and Medical Physics took place for her thesis titled:

(Comparison of the Antibacterial Impact of Biosynthesized Selenium Nanoparticles in the Absence and Presence of an Electric Field).

The objectives of the study:

• Preparation of SeNPs nanoparticles biologically from Ralstonia mannitolilytica.

• Characterization of biosynthesized selenium nanoparticles using Ralstonia mannitolilytica isolated from soil, along with various tests, including UV-V spectroscopy, Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), and FTIR.

• Investigating the effect of selenium nanoparticles against both gram-positive and gram-negative bacteria with and without the application of an electric field.

• Studying the impact of selenium nanoparticles on bacterial toxicity and cytotoxicity (in vitro and in vivo) in the presence and absence of an electric field.

• Evaluating the cytotoxic effects of selenium nanoparticles against cells.

The defense committee consisted of:

• Prof. Dr. Rasha Sabeeh Ahmed (Chair)

• Prof. Dr. Firas Sabeeh Mohammed (Member)

• Assist. Prof. Dr. Jenan Hussein Taha (Member)

• Assist. Prof. Dr. Mazin Kamel Hamed (Supervisor)
