Differentiated neuroblastoma cells (SH-SY5Y) were used to study the effects of lowstatic magnetic fields (SMFs) and extremely low frequency electromagnetic fields (ELF-EMFs) on the structure of DNA. Fourier Transform Infrared (FTIR) spectroscopy analysis showed that exposures to a SMF at 2mT and to a 50Hz EMF at 0.7mT produced peakÂ’s centroid shift and significant decreases of the phosphate absorption bands in the infrared region of DNA. The exposure also induced significant increase in reactive oxygen species (ROS) production in comparison to control confirming this scenario.
