Biomedical Applications of Magnetic Nanoparticles

Abstract

Magnetic nanoparticles are widely used in biomedical applications due to their small size, exotic properties, and processability. The main uses of magnetic nanoparticles in biomedicine are categorized into analytical and therapeutic applications. Under analytical applications, magnetic nanoparticles are used as magnetic carriers in separation processes, biosensors for detecting molecular recognition events, and contrast agents for magnetic resonance imaging. Main therapeutic applications include the use of magnetic nanoparticles for delivery of various drugs and bioactive compounds into cells as well as for hyperthermia during cancer therapy. The applications of magnetic nanoparticles in biomedicine must confirm strict requirements on the properties of the particles. It is a continuous challenge to produce reliable nanomagnets with the correct characteristics for biomedical applications.
