通过将流体几何限制在亚毫米尺度，微流体提供了一个与宏观世界截然不同的物理环境，这是显着增强的表面效应的结果。这种环境的特点是层流和惯性颗粒行为、短扩散距离和大大增强的热交换。近二十年来，微流控技术在生物技术、生物技术等各个领域得到了快速发展。分析科学；和诊断；以及物理、化学和生物研究。另一方面，另一个领域仍在不断涌现。随着纳米材料和软物质研究的进步，已经有一些关于在微流控芯片上合成这些材料的尝试中发现的优势的报道。由于纳米材料和软物质的形成对构建块的供给环境敏感，因此与传统的本体合成相比，微流体独特的物理环境以及与其他力场耦合的有效性为形成新产品提供了很多可能性。本综述总结了利用微流控技术生产新型功能材料的最新进展，例如生成窄且受控尺寸分布的颗粒、结构化杂化材料和具有新结构的颗粒，以更快的速度完成反应和新的反应路线，并能够更有效和高效地控制反应。最后还讨论了该领域未来的发展趋势。
By geometrically constraining fluids into the sub-millimeter scale, microfluidics offers a physical environment largely different from the macroscopic world, as a result of the significantly enhanced surface effects. This environment is characterized by laminar flow and inertial particle behavior, short diffusion distance, and largely enhanced heat exchange. The recent two decades have witnessed the rapid advances of microfluidic technologies in various fields such as biotechnology; analytical science; and diagnostics; as well as physical, chemical, and biological research. On the other hand, one additional field is still emerging. With the advances in nanomaterial and soft matter research, there have been some reports of the advantages discovered during attempts to synthesize these materials on microfluidic chips. As the formation of nanomaterials and soft matters is sensitive to the environment where the building blocks are fed, the unique physical environment of microfluidics and the effectiveness in coupling with other force fields open up a lot of possibilities to form new products as compared to conventional bulk synthesis. This Perspective summarizes the recent progress in producing novel functional materials using microfluidics, such as generating particles with narrow and controlled size distribution, structured hybrid materials, and particles with new structures, completing reactions with a quicker rate and new reaction routes and enabling more effective and efficient control on reactions. Finally, the trend of future development in this field is also discussed.
