Used in targeted drug delivery systems to transport medications directly to diseased cells, especially in cancer therapy, minimizing damage to healthy tissues.

Employed in magnetic resonance imaging (MRI) as contrast agents to enhance image clarity and improve diagnosis of tumors and inflammatory conditions.

Applied in biosensors and diagnostic assays for rapid and efficient separation of biomolecules such as DNA, proteins, and pathogens from complex mixtures.

Utilized in environmental remediation to remove heavy metals and organic pollutants from wastewater through magnetic separation after adsorption.

Commonly used in immunoassays and cell separation techniques due to their ability to bind selectively to specific cells or molecules under external magnetic fields.

Stable in biological environments, making them suitable for in vivo applications where prolonged circulation and low immune response are required.
