50 Hz Electromagnetic Field Produced Changes in FTIR Spectroscopy Associated with Mitochondrial Transmembrane Potential Reduction in Neuronal-Like SH-SY5Y Cells

Figure 2

ATR spectra of neuroblastoma cells in the spectral IR region from 1800 to 1250 cm−1. (a) after 4 h of exposure to 50 Hz EMF at 50 μT; (b) after 4 h of exposure to 50 Hz EMF at 0.8 mT; (c) after 4 h of exposure to 50 Hz EMF at 1.4 mT. The increase in β-sheet content with respect to α-helix component in amide I region and the increase at 1740 cm−1 vibration band in the amide I region appeared clearly after the exposure to 50 Hz EMF at the intensity of 0.8 mT. The β-sheet content increased more after exposure to 1.4 mT, as reported in Table 2.
