Investigation of Cytotoxicity of Biosynthesized Zinc Oxide Nanoparticles Using (Cress Extract): A New Master’s Thesis

College of Education, Iraqi University discussed a master’s thesis on the investigation of cytotoxicity using the biosynthetic zinc oxide nanoparticles (HdFN) cell line using cress extract (Lepidium sativum) and the study of its antibacterial activity against Pseudomonas aeruginosa isolated locally, On Sunday, 10/2/2022.

The thesis presented by  (Wissam Issa Abdel )from Department of Biological Sciences aimed to use zinc oxide nanoparticles and aqueous extract of cress plant against the normal cell line (HdFn) and the melanoma cell line (A375) by (MTT) assaying Pseudomonas aeruginosa was isolated and diagnosed morphologically, microscopically and by biochemical methods using PCR.

The toxicity of zinc oxide nanoparticles and the aqueous extract of Cress against Pseudomonas aeruginosa was also investigated. The study concluded that the effect of zinc oxide nanoparticles has greater toxicity than Cress aqueous extract against normal cells (HdFn) and skin cancer cells (A375), and that zinc oxide nanoparticles and Cress aqueous extract have a toxicity that inhibits the growth of Pseudomonas aeruginosa.

The thesis was approved with Excellence grade.
