Iron oxide nanoparticles (Fe3O4) in organic solvents have a variety of applications such as probing agents to indirectly study the structure of mixed SAMs, solid phase extraction, anode materials for Li-ion batteries, and electromagnetic interference (EMI) shielding materials.
These particles are compatible with many spin-coaters and dip-coaters for applications that require the fabrication of films.
