Unfolding and aggregation of myoglobin can be induced by three hours exposure to mobile phone microwaves: A FTIR spectroscopy study

摘要

The effects of 3 hours exposure to mobile phone microwaves at 1765 MHz at the power density around 800 mW/m~2 on the secondary structure of myoglobin in D_2O solution were investigated by Fourier transform infrared spectroscopy. A significant shift to lower frequencies of the amide I vibration was observed after exposure. Furthermore, a significant increasing of the β-sheet components with respect to the α-helix content after exposure was highlighted after applying Fourier self-deconvolution analysis in the amide I region. These results led to the conclusion that mobile phone microwaves induce unfolding of myoglobin and formation of aggregates.
