摘要

光镊技术具有无损伤、快速灵敏地捕获微粒的特点，已被广泛应用于物理学、生物传感和化学等领域，但由于光镊是一种新兴技术，光学理论抽象繁琐，且光镊系统结构复杂，实验演示仪器贵重，因此，在现有物理实验课程教学中光镊实验演示仍然十分困难。本文聚焦于光镊在大学物理实验教学课程中的痛点问题，基于光镊的理论方法提出了一种基于单光束梯度力光阱原理的微粒捕获装置，通过实验演示和研究分析，得出实验现象符合光镊捕获微粒的研究规律，且能够观察到明显的粒子捕获过程的结论。基于单光束梯度力光阱原理的微粒捕获装置体积小巧，经济实用，适合在大学物理实验课程中推广应用。

Abstract:

Optical tweezers technology has the characteristics of non-destructive ,fast and sensitive capture ofparticles.It has been widely used in physics , biosensing and chemistry.However,because optical tweezers is anemerging technology, the abstract optical theory is complicated, the structure of optical tweezers system iscomplex, and experimental demonstration instruments are expensive. Therefore , it is still very dificult todemonstrate optical tweezers experiments in the teaching of existing physics laboratory courses. lt focuses on thedifficult problems of optical tweezers in university physics experimental teaching courses, and proposes aparticle capture device based on the principle of single-beam gradient force optical trap by using the theoreticamethod of optical tweezers, and concludes that the experimental phenomenon conforms to the research law ofoptical tweezers capturing particles through experimental demonstration research and analysis , and obviousparticle capture process can be observed.Based on the principle of single-beam gradient force trap ,the particlecapture device is compact, economical and practical, and more suitable for promotion and application inuniversity physics experimental courses.

Key words: single-beam gradient force particulate capture optical tweezers experimental demonstration
