最近将声表面波(SAW)技术引入芯片实验室平台,开辟了微流控领域的新前沿。这种SAW微流控具有许多优点:制造简单、生物兼容性高、流体驱动速度快、通用性强、紧凑且廉价的设备和附件、非接触式颗粒操纵以及与其他微流控部件的兼容性。我们相信,这些优势使声表面波微流体在生物、化学、工程和医学的各种应用中发挥着重要作用。在这篇综述文章中,我们讨论了支撑锯片的理论以及它们与颗粒和悬浮在其中的接触流体的相互作用。然后,我们回顾了迄今为止展示的支持SAW的微流控设备,首先是通过使用移动锯来完成流体混合和传输的设备;然后,我们回顾了使用立式锯实现的最新创新,这些创新实现了粒子/细胞聚焦、分选和构图等操作。最后,展望和评价了声表面波微流体学科的下一步发展方向。
The recent introduction of surface acoustic wave (SAW) technology onto lab-on-a-chip platforms has opened a new frontier in microfluidics. The advantages provided by such SAW microfluidics are numerous: simple fabrication, high biocompatibility, fast fluid actuation, versatility, compact and inexpensive devices and accessories, contact-free particle manipulation, and compatibility with other microfluidic components. We believe that these advantages enable SAW microfluidics to play a significant role in a variety of applications in biology, chemistry, engineering, and medicine. In this review article, we discuss the theory underpinning SAWs and their interactions with particles and the contacting fluids in which they are suspended. We then review the SAW-enabled microfluidic devices demonstrated to date, starting with devices that accomplish fluid mixing and transport through the use of travelling SAW; we follow that by reviewing the more recent innovations achieved with standing SAW that enable such actions as particle/cell focusing, sorting, and patterning. Finally, we look forward and appraise where the discipline of SAW microfluidics could go next.
