Abstract

Optical tweezers technology utilizes the optical potential well generated by a focused laser beam to achieve precise manipulation of micro and nanoparticles. Based on the optical tweezers platform, the motion behavior and dynamic laws of particles are deeply studied, which can reveal the transport mechanism of complex systems. Based on summarizing the principles and experimental methods of optical tweezers technology, this article systematically summarizes the typical force characteristics of particles in optical tweezers, focusing on the dynamic research progress of single particle non-equilibrium state, double particle coupling, and multi-particle cluster system, laying a theoretical foundation for expanding the application of optical tweezers technology in physics, chemistry, biology, and other fields.
