Fig. (1) Representative IR spectra from 3500 to 1350 cm-1 of hemoglobin in bidistilled water solution after 3 h of exposure to 1750 MHz mobile phone MWs at the power density of 950 mW/m2 (red line refers to exposed sample). Significant increase in intensity of Amide I vibration band (p < 0.05) is indicated by an arrow.
