The effect of tobacco concentration on the DNA blood samples using the AC electrical impedance spectroscopy.

The electrical impedance of DNA of female and male healthy blood sampleswas recorded in vitro. The Nyquist Plots for female and male samples were of the samefeature. The peak of each Nyquist Plot was increased and shifted to higher real electricalimpedance values as tobacco concentration increased from 1μl to 4μl. The Bode moduleplots confirm these results for female and male DNA blood samples. The start values ofthe A.C electrical resistance and electrical capacitance were 95.98KΩ and 2.36μF forfemale DNA and were 183.6KΩ and 5.47μF for male DNA, respectively. These valueswere changed to be 82.65KΩ and 3.18 μF for female DNA and 177.35KΩ and 5.30μF formale DNA, respectively, under the effect of 1μl tobacco concentration for each of them.The increase of tobacco concentration gradually more than 1μl and up to 4μl, these valuesreach 139.63KΩ and 5.81μF for female DNA, and 219.42KΩ and 9.00μF for male DNA,respectively. These results were attributed to the increase of covered area in the lungsalveolus by the smoke in female and male DNA. Finally, these results illustrate that thecovered areas of the lung alveolus by the smoke were wider in the case of female DNAthan that of male DNA.
