表面声波（saw）是在压电晶体表面形成的机电波。由于它们易于构建和操作，SAW设备已被证明是直接化学传感或上游微流体处理和样品制备的多功能和强大的平台。本文综述了用于化学传感和分析的SAW器件的最新进展。讨论了在气体和液体介质中使用声表面波技术进行化学检测，以及为下一代声表面波传感器指明道路的最新制造进展。同样，本书也涵盖了SAW器件作为微流控平台的应用和进展，从雾化和混合到裂解和细胞粘附研究的新方法。最后，提出了该领域的潜在新方向和前景，并特别关注了将SAW技术用于生物分析应用的潜在策略。
Surface acoustic waves (SAWs), are electro-mechanical waves that form on the surface of piezoelectric crystals. Because they are easy to construct and operate, SAW devices have proven to be versatile and powerful platforms for either direct chemical sensing or for upstream microfluidic processing and sample preparation. This review summarizes recent advances in the development of SAW devices for chemical sensing and analysis. The use of SAW techniques for chemical detection in both gaseous and liquid media is discussed, as well as recent fabrication advances that are pointing the way for the next generation of SAW sensors. Similarly, applications and progress in using SAW devices as microfluidic platforms are covered, ranging from atomization and mixing to new approaches to lysing and cell adhesion studies. Finally, potential new directions and perspectives on the field as it moves forward are offered, with a specific focus on potential strategies for making SAW technologies for bioanalytical applications.
