Electromagnetic forces and torques enable many key technologies, including optical tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical process: the interaction of an oscillating electric field with a particle of matter. This work provides a unified framework to understand this interaction both when considering fields oscillating at low frequencies─dielectrophoresis─and high frequencies─optical tweezers. We draw useful parallels between these two techniques, discuss the different and often unstated assumptions they are based upon, and illustrate key applications in the fields of physical and analytical chemistry, biosensing, and colloidal science.
电磁力和转矩促成了许多关键技术，包括光镊技术或介电泳技术。有趣的是，这两种技术都依赖于相同的物理过程：振荡电场与物质粒子之间的相互作用。这项工作提供了一个统一的框架，以便在考虑低频振荡场（介电泳）和高频振荡场（光镊）时理解这种相互作用。我们在这两种技术之间建立了有用的类比，讨论了它们所基于的不同且往往未阐明的假设，并举例说明了物理化学、分析化学、生物传感和胶体科学领域的关键应用。
