General description

Iron oxide(II,III), magnetic nanoparticles solution (Fe3O4) is an organic solvent dispersed nanoparticle solution, which can be synthesized by the thermal decomposition of iron acetylacetonate in 2-pyrrolidone. It is majorly used in biomedical applications due to its magnetic properties, particle size, and surface properties.
It contains <1.0% oleic acid stabilizing ligands.
Concentration 5mg/ml includes total weight nanocrystals plus ligands.

Application

Fe3O4 can be used in the targeting and imaging of tumor cells for cancer therapy-based applications. It may also be used in the separation of tumor cells from fresh whole blood. It can also be used as an effective material in drug delivery systems and magnetic resonance imaging (MRI).
