光学镊子

用光学镊子夹起一串DNA，研究微小的分子发动机中的物理原理。

Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors .

光的吸收可以同时导致光束的自旋角动量或轨道角动量转移给微米粒子，就像光学镊子一样引起粒子的转动，从而形成光学扳手。

Absorption of the light allows both the spin and orbital angular momentum of a light beam to be transferred to microscopic particles held within optical tweezers , forming an optical spanner .

另外，简单介绍了圆对称光束作为光学镊子和光学扳手在微米粒子和生物细胞的光学导引、囚禁与操控等领域中的应用。

In addition , as optical tweezers and spanners , the potential applications of cylindrical symmetric beams in optical guiding , traps , manipulations and controls of microscopic particles and biological cells are briefly discussed .
