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

Abstract

Overview

In this study, the localization of magnetic nanoparticles in various multicellular organisms was examined. Both biogenic and nonbiogenic magnetic nanoparticles were explored.

Findings

• Using atomic force microscopy and magnetic force microscopy, the presence of chain-like structures of nanoparticles was identified in organ slices from animals, plants, and fungi.
• These nanoparticles are positioned in vital locations such as the capillary walls in animals and conducting tissues in plants and fungi, contributing to the organism's transport systems.
• The study also introduces a new concept for the purpose of biogenic magnetic nanoparticles, suggesting they may act as ferrimagnetic organelles.

Conclusion

The interaction of biogenic magnetic nanoparticles with artificial nanoparticles used in drug delivery and MRI imaging poses a potential risk, including vascular occlusion, and should be carefully considered in medical applications.
