Modifications of human lymphoblastoid cells, induced by low frequency magnetic field: A three dimensional atomic force microscopy study.

Air operating atomic force microscopy (AFM) has been used to study human B lymphoblastoid (Raji) cells exposed to a 50 Hz 2mT sinusoidal magnetic field (MF), up to 64 hours. A statistical analysis performed on mean height and membrane roughness of the cells showed a loss of microvilli and several modifications of the overall shape and membrane surface at increasing MF exposure.
