The switch which has been discovered, with its diameter of only 1.2 nanometers, could be used as a tiny magnetic reservoir in molecular electronics. Most of all, hard disk manufacturers may be interested in this, as a higher storage capacity can be achieved by reducing the size of the magnetic particles on the surface of the disks.
Professor Herges also believes the use of the magnetic switch in the medical field is feasible: "The record player molecule can be used intravenously as a contrast agent in MRT (magnetic resonance tomography) in order to search for tumors or constricted blood vessels. Initial tests in the University Medical Center Schleswig-Holstein's neuroradiology department were successful."
