Doaa Rifaat Jassim, a lecture in the Department of Forensic Evidence at the College of Science at Al-Nahrain University, obtained a doctorate degree from the College of Science for Girls at the University of Baghdad after discussing her thesis tagged
"Preparation of some nanomaterials using cold plasma jet for physical and medical applications"
This thesis dealt with the preparation of copper particles with a selenium core shell (Cu:Se) using cold plasma jets and converting them into transparent crystalline films for use in physical and medical applications.
The study aimed to manufacture nanoparticles with a structure (Cu:Se) and use them in physical applications, where the effect of changing the ratio of (Cu:Se) on the structural, morphological, optical and electrical properties of the resulting nanostructures and in medical applications was investigated, where the study included its effect on the line of breast cancer cells MDA and normal cells REF in addition to its effect on L.Tropica parasites.The results showed that the rates of change of resistance and sensitivity of the samples depend on surface characteristics such as roughness, where the highest inhibition rate of cancer cells (80%) was achieved after 48 hours and the greatest inhibition rate of leishmania cells (73%) after 48 hours as well, and cytotoxicity reached (20.33%-24.33%) after 24 and 48 hours respectively.
