Tracking of magnetic nanoparticle biodistribution

Nanotechnology holds great promise for medicine, but there are also many unknowns. Magnetic nanoparticles (MNPs), for example, can carry drugs directly to a tumor, but we don’t know their ultimate fate in the body.
Dr. Lucia Gutierrez Marruedo uses their magnetic properties to quantify MNPs in tissue and measure how they degrade over time. Knowing how they interact with the body could tell us about their performance and potential side effects and lead to tailored treatments for disease.
