With the prevalence of wireless radio frequency (RF) devices, interest is growing to more fully understand the effect of RF on biological tissue. This research explores how ?DNA interacts with RF energy. By sweeping a radio frequency range from 1 GHz to 8.5 GHz we hope to observe if specific frequencies show significantly elevated RF energy-?DNA interaction (e.g. either absorbed and/or reflected). Our procedure is as follows: 1) Set up RF equipment (horn antennas and network analyzer), 2) vary frequency from 1- 8.5GHz at a RF power level of 0 dBm, 3) vary same frequency sweep with buffer in the cell culture wells, and next with DNA and buffer in the cell-culture wells, and 4) the frequency sweep was repeated 100 times with a duration of 1.0 second per sweep. The results indicate regions of RF- ?DNA interaction around 3 and 3.5 GHz.
随着无线射频（RF）设备的普及，人们越来越有兴趣更全面地了解射频对生物组织的影响。本研究探讨了DNA如何与射频能量相互作用。通过在1吉赫兹至8.5吉赫兹的射频范围内进行扫描，我们希望观察特定频率是否显示出显著增强的射频能量与DNA的相互作用（例如，吸收和/或反射）。我们的步骤如下：1）设置射频设备（喇叭天线和网络分析仪），2）在射频功率电平为0分贝毫瓦的情况下，将频率从1 Ghz变化到8.5 Ghz，3）在细胞培养孔中有缓冲液的情况下以及接下来在细胞培养孔中有DNA和缓冲液的情况下，对相同的频率扫描进行变化，并且4）以每次扫描持续1.0秒的方式将频率扫描重复100次。结果表明在3吉赫兹和3.5吉赫兹左右存在射频与DNA相互作用的区域。
