Highly sensitive force measurements of a single microscopic particle with femto-Newton sensitivity have remained elusive owing to the existence of fundamental thermal noise. Now, researchers have proposed an optically controlled hydrodynamic manipulation method, which can measure the weak force of a single microscopic particle with femto-Newton sensitivity.
由于存在基本热噪声，对单个微观粒子进行具有飞牛顿灵敏度的高灵敏度力测量一直难以实现。现在，研究人员提出了一种光控流体动力学操纵方法，该方法可以测量单个微观粒子具有飞牛顿灵敏度的微弱力。
