nanoComposix iron oxide nanoparticles are composed of magnetite (Fe3O4) and exhibit superparamagnetic properties. In addition to their magnetic properties, iron oxide nanoparticles have unique optical, physical, and chemical properties that make them candidates for use in a variety of applications, ranging from imaging contrast agents and hyperthermia therapy to biosensors and catalysis.
nanoComposix has the ability to customize particle size and surface chemistry to integrate into your application – learn more about our capabilities below.

Custom Synthesis & Contract Development
While many other manufacturers use “top-down” synthesis methods to break down bulk iron oxide into nanoparticles, nanoComposix uses colloidal synthesis methods to fabricate iron oxide nanoparticles, yielding high quality, high purity particles with precise size control.
Summary of Iron Oxide Nanoparticle Synthetic Capabilities
Size
We are able to tune single crystal iron oxide nanoparticle size from 5 nm to 30 nm.
Surface
The native oxide surface is a scaffold for surface modifications ranging from metal oxide shells such as silica to organic ligands.
Concentration & Matrix
Our oleic acid capped iron oxide nanoparticles are typically supplied at 5 mg/mL in toluene. Additional concentrations and matrices, including dried samples, can be provided upon request.
