研究了单个DNA分子的弛豫。该实验系统由光镊和一个微米大小的珠子组成，珠子通过一个单一的双链DNA分子拴在样品的底部。珠减慢DNA从强拉伸构型的松弛，使得其通过拉伸平衡状态。这允许的弛豫轨迹，这是在良好的协议与实验的理论描述。
The relaxation of a single DNA molecule is studied. The experimental system consists of optical tweezers and a micron-sized bead that is tethered to the bottom of the sample by a single double-stranded DNA molecule. The bead slows down the DNA relaxation from a strongly stretched configuration such that it is passing through stretched equilibrium states. This allows for a theoretical description of the relaxation trajectory, which is in good agreement with experiment.
