Description and Specification Magnetite Nanoparticles

Magnetite nanoparticles (Fe₃O₄) a tiny iron oxide particles measuring between 1 and 100 nanometers in size. Due to its small size and large surface area, it is helpful in medicine and technology. This particles can be made in uniform shapes and sizes and have unique magnetic properties.

Magnetite is a naturally found mineral in the air. When inhaled, it impacts the lungs, heart, and brain. This nanoparticles is engineered variants of magnetite that is designed to be harmless. Scientists use it in various fields. In environmental remediation, it can adsorb pollutants from water. The particles and pollutants can then be removed by magnetic separation.

Magnetite is an iron oxide nanoparticle that is superparamagnetic at room temperatures and has a high surface area-to-volume ratio. Scientists use magnetite in different fields.
