Magnetic Nanoparticles and their Applications

The magnetic nanoparticles attach to particles in the blood stream called microvesicles which originate in brain cancer cells. NMR is then used to detect these microvesicle/magnetic nanoparticle clusters, allowing an early diagnosis. Iron oxide nanoparticles can be used to improve Magnetic Resonance Imaging (MRI) of cancer tumors.

Intracranial thermotherapy using magnetic

Thermotherapy using magnetic nanoparticles was tolerated well by all patients with minor or no side effects. Median maximum intratumoral temperatures of 44.6 degrees C (42.4-49.5 degrees C) were measured and signs of local tumor control were observed. In conclusion, deep cranial thermotherapy using magnetic nanoparticles can be safely applied on glioblastoma multiforme patients. Publication
