论文摘要
光学离心机已成为在许多领域中实现颗粒的离心机运动的有前途的工具。在本文中，我们报告了一种新型的光学离心机，该离心机是由全息光晶夹中光的横时梯度引起的光学侧向力驱动的。它具有显着的优势，包括快速速度，占地面积小，灵活设计和易于控制。通过使用AU和聚苯乙烯纳米颗粒，通过实验证明了光学清除和排序作为应用示例。结果表明，光学离心机表现出色，同时用作光学清除和光学分类。例如，其在光学清除中的离心速度可以在短时间内达到120μm/s的峰值速度，这对于微流体系统中各种颗粒的光学操纵非常可取。这项研究为实现光学操作的新功能提供了一种方法，包括光学清除和光学分类。
Optical centrifuge has emerged as a promising tool for achieving centrifuge motion of particles in many fields. Herein, we report a novel optical centrifuge, as driven by optical lateral force arising from transverse phase gradient of light in holographic optical tweezers. It has remarkable advantages, including rapid speed, small footprint, flexible design and easy control. The optical clearing and sorting as application examples have been experimentally demonstrated by using Au and polystyrene nanoparticles. The results show that the optical centrifuge exhibits excellent performance, while used as optical clearing and optical sorting. For instance, its centrifuge velocity in optical clearing can reach its peak speed of 120 μm/s in a short time, which is highly desirable for optical manipulation of various particles in microfluidic systems. This study opens a way for realizing novel functions of optical manipulation including optical clearing and optical sorting.
