A scientific seminar on “The influence of iron nanoparticles on internal organs and embryonic development stages of common carp (Cyprinus carpio L., 1758)” was held at the Faculty of Biology of Baku State University (BSU).

Aysel Hajiyeva, a doctoral student at the Department of Biophysics and Biochemistry, made a report on the topic. In the presentation, the bioaccumulation properties of iron oxide nanoparticles (Fe₃O₄) in the small intestine and liver of common carp grown in aquaculture conditions, as well as their effect on embryonic development, were evaluated using light and electron microscopy methods. The results of the studies showed that significant pathomorphological changes were observed, such as the collapse of microvilli, cytoplasmic edema, damage to mitochondria and vascular endothelium. At the same time, it was determined that nanoparticles penetrated enterocytes, hepatocytes and erythrocytes and systematically accumulated in various tissues.

The seminar participants emphasized the scientific novelty and practical importance of the topic, and noted the importance of further investigating the potential risks associated with nanoparticles, as well as their possible effects on the environment and aquatic ecosystems.
