Magnetic hematite, also known as magnetite, is a naturally occurring mineral that has been used for centuries. It is a ferromagnetic material, which means that it is attracted to magnets. This property makes it useful in a variety of applications, including compasses, magnetic resonance imaging (MRI), and data storage.
In recent years, there has been a growing interest in the use of magnetic hematite in biomedical applications. This is due to its high magnetic susceptibility, which allows it to be easily manipulated by magnetic fields. This property makes it a promising candidate for use in targeted drug delivery and tissue engineering.
