Superparamagnetic iron–platinum particles

From WikiMD's Food, Medicine & Wellness Encyclopedia

Superparamagnetic iron–platinum particles (SPIPs) are a type of magnetic nanoparticle that have potential applications in biomedicine, particularly in the field of magnetic resonance imaging (MRI). They are composed of an iron core coated with a thin layer of platinum, which makes them superparamagnetic. This means that they can be magnetized and demagnetized quickly, which is important for applications like MRI where rapid signal changes are required. Additionally, the platinum coating on the surface of the particles makes them biocompatible and resistant to oxidation, making them suitable for use in biomedical applications.
