In this mini-review, recent advances on the role of a focused laser in micro- and nanofluidic systems is widely introduced with special interest in thermo-fluid dynamical aspects and their importance in optical manipulation. As a brief introduction to microfluidic systems, we describe the advantages and challenges of the use of micro- and nanoscale confinement in optical trapping, as well as standard fabrication techniques for micro- and nanofluidic systems. From thermo-fluid dynamical viewpoints, various phenomena that accompany a laser irradiation to fluidic devices, are explained in detail. These phenomena can affect the optical trapping of target materials significantly, and are classified into two categories: one that induces the fluid flow around the target and another that directly acts on it as an external force. These classes are reviewed by shedding light on some recent cutting-edge researches for optical manipulation. Some applications using thermo-fluid dynamics in microfluidic systems for the measurement of optical forces and for the separation, measurement, and detection of target materials are also introduced.

在这篇小型评论中，广泛介绍了聚焦激光在微流体和纳米流体系统中的作用的最新进展，特别关注热流体动力学方面及其在光学操纵中的重要性。作为对微流控系统的简要介绍，我们描述了在光捕获中使用微米级和纳米级限制的优势和挑战，以及微流控系统和纳米流控系统的标准制造技术。从热流体动力学的角度，详细解释了伴随激光照射到流体装置的各种现象。这些现象会显着影响目标材料的光捕获，并分为两类：一类诱导目标周围的流体流动，另一类作为外力直接作用于目标。通过阐明最近的一些光学操作前沿研究来回顾这些课程。还介绍了在微流体系统中使用热流体动力学测量光学力以及分离、测量和检测目标材料的一些应用。
