Chain-Like Structures of Biogenic and Nonbiogenic Magnetic Nanoparticles in Vascular Tissues

Abstract

Overview

This study investigates the characteristics and localization of magnetic nanoparticles in various multicellular organisms, analyzing both biogenic (naturally occurring) and nonbiogenic (artificial) types.

Findings

• Utilization of atomic force microscopy and magnetic force microscopy to examine organ slices from animals, plants, and fungi.
• Revealed the presence of magnetic nanoparticles localized in chain formations within the capillary and conducting tissue walls.
• Discussion of the potential role of these chains as ferrimagnetic organelles with specific functions in multicellular organisms.

Conclusion

The study highlighted the critical implications of magnetic nanoparticles as essential components in medical applications such as drug delivery and MRI. Furthermore, it emphasized the potential health risks, particularly the formation of aggregates leading to vascular occlusion, necessitating mindful consideration in the design of biomedical devices.
