Nanoscale iron particles are sub-micrometer particles of iron metal. Due to their high catalytic activity, permanent magnetic properties, low toxicity, and strong adsorption capacity, iron-based nanoparticles are widely utilized in drug delivery, production of magnetic tapes (e.g., camcorders and backup tapes of computers), gene therapy, and environmental remediation.
