摘要

纳米级力测量高斯激光束产生的光学捕获捕获了一个微球，微球与红细胞、DNA和蛋白质相互作用，从而实现了皮牛顿级精度的精确力测量。力检测的基本原理通过方程F = kΔx来强调，其中F是力，k是陷阱刚度，Δx是微球的位移。该技术为探索纳米科学和生物物理学中的生物力学相互作用提供了有力的工具。更多的细节可以在文章2403140中找到曾淑文，王玉野，陈佳杰和同事。

Nanoscale Force Measurement

An optical trapping generated from a Gaussian laser beam traps a microsphere, which interacts with red blood cells, DNA, and proteins, enabling precise force measurements with piconewton-level precision. The fundamental principle of force detection is highlighted by the equation F = kΔx, where F is the force, k is the trap stiffness, and Δx is the displacement of the microsphere. This technique provides a powerful tool for probing biomechanical interactions in nanoscience and biophysics. More details can be found in article 2403140 by Shuwen Zeng, Yuye Wang, Jiajie Chen, and co-workers.
