Cardioprotective activity of iron oxide nanoparticles [PDF]

Scientific Reports, 2015
AbstractIron oxide nanoparticles (IONPs) are chemically inert materials and have been mainly used for imaging applications and drug deliveries. However, the possibility whether they can be used as therapeutic drugs themselves has not yet been explored. We reported here that Fe2O3nanoparticles (NPs) can protect hearts from ischemic damage at the animal,

Synthesizing efficacious genistein in conjugation with superparamagnetic Fe₃O₄ decorated with bio-compatible carboxymethylated chitosan against acute leukemia lymphoma [PDF]

, 2014
Background Genistein (C15H10O5) is a soy isoflavone with anti-cancer properties such as inhibition of cell growth, proliferation and tumor invasion, but effective dosage against hematopoietic malignant cells was not in non-toxic range.
