In this study, we proposed a method to measure the escape time of DNA molecules trapped in front of a nanogap by concentrating DNA molecules in front of a nanogap and observing the escape process upon their entry. We measured the escape time for λDNA molecules entering a 25nm deep nanogap in the semi-dilute unentangled regime to verify the validity of our method. Our obtained escape time was the same order of the relaxation time of the DNA molecule, represented by the Rouse model.

测量纳米间隙前浓缩DNA分子的逃逸时间

在这项研究中，我们提出了一种通过将纳米分子前的DNA分子浓缩并观察其进入后的逃逸过程来测量捕获在纳米隙前的DNA分子逃逸时间的方法。我们测得的逃逸时间为λ进入半稀未缠结政权的25nm深纳米间隙来验证我们的方法的有效性DNA分子。我们获得的逃逸时间与以Rouse模型表示的DNA分子的弛豫时间相同。
