A team of researchers has developed a new method of generating an oscillating magnetic field (OMF) that eradicates cancer cells via a wearable device. These studies were made possible by the prior invention of a wearable miniaturized multifocal transcranial magnetic stimulator by Santosh Helekar, MD, PhD, associate professor of neurosurgery, and Henning Voss, associate professor of physics in radiology at Weill Cornell Medical College. The device uses microstimulators, called oncoscillators, that rotate strong neodymium permanent magnets devised patterns. Helekar and his colleagues have produced selective anti-cancer effects in patient-derived GBM and breast cancer cells in culture without damaging cultured normal cells.
