Parallel β‐sheet vibration band increases with proteins dipole moment under exposure to 1765 MHz microwaves

Effects of exposure of 4 h to mobile phones microwaves at 1765 MHz at a power density around 940 mW/m2 on four typical proteins (hemoglobin in H2O solution, and myoglobin, bovine serum albumin, and lysozyme in D2O solution) were studied by means of Fourier Transform Infrared spectroscopy and Fourier self‐deconvolution analysis. Increase in intensity of parallel β‐sheet component around 1635 cm−1 was observed after exposure of hemoglobin, myoglobin, and bovine serum albumin, showing that a mechanism of unfolding occurred after exposure, whereas no appreciable change in the amide I region occurred after lysozyme exposure. In addition, a relationship between protein dipole moment and protein unfolding rate was demonstrated with a correlation coefficient r = 0.973 and 95% confidence interval.
