Abstract

Optofluidics is an exciting new area of study resulting from the fusion of microfluidics and photonics. It broadens the application and extends the functionality of microfluidics and has been extensively investigated in biocontrol, molecular diagnosis, material synthesis, and drug delivery. When light interacts with a microfluidic system, optical force and/or photothermal effects may occur due to the strong interaction between light and liquid. Such opto-physical effects can be used for optical manipulation and sensing due to their unique advantages over conventional microfluidics and photonics, including their simple fabrication process, flexible manipulation capability, compact configuration, and low cost. In this review, we summarize the latest progress in fiber optofluidic (FOF) technology based on optical force and photothermal effects in manipulation and sensing applications. Optical force can be used for optofluidic manipulation and sensing in two categories: stable single optical traps and stable combined optical traps. The photothermal effect can be applied to optofluidics based on two major structures: optical microfibers and optical fiber tips. The advantages and disadvantages of each FOF technology are also discussed.

摘要

光流体学是微流体学与光子学融合产生的一个令人兴奋的新研究领域。它拓宽了微流体学的应用范围并扩展了其功能，已在生物控制、分子诊断、材料合成和药物递送等方面得到广泛研究。当光与微流体系统相互作用时，由于光与液体之间的强相互作用，可能会产生光力和/或光热效应。由于这些光物理效应相对于传统微流体学和光子学具有独特优势，包括制造工艺简单、操作灵活、结构紧凑和成本低等，因此可用于光学操控和传感。在本综述中，我们总结了基于光力和光热效应在操控和传感应用中的光纤光流体（FOF）技术的最新进展。光力可用于两类光流体操控和传感：稳定的单光阱和稳定的组合光阱。光热效应可基于两种主要结构应用于光流体学：光学微纤维和光纤尖端。还讨论了每种FOF技术的优缺点。
