The successful design of nanofluidic devices for the manipulation of biopolymers requires an understanding of how the predictions of soft condensed matter physics scale with device dimensions. Here we present measurements of DNA extended in nanochannels and show that below a critical width roughly twice the persistence length there is a crossover in the polymer physics.
用于生物聚合物操控的纳米流体装置的成功设计需要了解软凝聚态物理的预测如何随装置尺寸而变化。在此，我们展示了在纳米通道中伸展的DNA的测量结果，并表明在大约为持久长度两倍的临界宽度以下，聚合物物理存在一个转变。
