Iron nanoparticle
open-in-new
<p>Nanoscale iron particles are sub-micrometer particles of <a href="/facts/Iron/QK1JYy8E">iron</a> metal. Due to their high <a href="/facts/Catalysis/LPBS7TQC">catalytic activity</a>, permanent magnetic properties, low toxicity, and strong <a href="/facts/Adsorption/ARH9peYM">adsorption</a> capacity, iron-based nanoparticles are widely utilized in <a href="/facts/Drug_delivery/vDfboXeT">drug delivery</a>, production of magnetic tapes (e.g., camcorders and backup tapes of computers), <a href="/facts/Gene_therapy/CaxRLfKM">gene therapy</a>, and <a href="/facts/Environmental_remediation/S6wKBuhm">environmental remediation</a>. </p>
