Publication number: 20160022300Abstract: The present invention provides a cell eradication method and a cell eradication principle for necrotizing a cell by agitating a cell using a physical turning force from the impression of an AC magnetic field, after preparing a magnetic nanowire having a dipole and introducing the magnetic nanowire into a cell. Therefore, the composition for inducing cell eradication of the present invention, when applied to a cell that is requested to be removed such as a cancer cell, can eradicate the cell by applying a physical impact through the rotation of the nanowire introduced inside the cell. Additionally, the heat generated from induced current from the magnetic field impression can add an effect of thennotherapy, and also, attaching a drug to the surface of the nanowire enhances the treatment effects.Type: ApplicationFiled: July 28, 2015Publication date: January 28, 2016Inventors: Sung Hoi CHOI, Jung Rae PARK, Young Keun KIM
