提出了一种用于操纵悬浮在微流体介质中的微米和纳米颗粒以及生物实体的PZT/玻璃毛细管致动器。PZT/玻璃毛细管谐振器能够在低电压驱动(1-20Vpp)的单个PZT/玻璃毛细管平台上实现生物分析能力，如收集、分离和混合分析物-这需要不同的驱动机制。这里介绍的致动器机构使生产成本效益高、电池供电的便携式诊断工具和护理设备成为可能。使用声阻抗作为辨别量，消除了对其他操纵机构施加的电解液、pH或磁性参数的依赖。
A PZT/glass capillary actuator for the manipulation of micro and nanoparticles and biological entities suspended in a microfluidic medium is presented. The PZT/glass capillary resonator enables bioanalytical capabilities such as collection, separation and mixing of analytes – which require different actuation mechanisms- on a single PZT/glass capillary platform at low voltage drives (1-20Vpp). Actuator mechanism presented here, enables production of cost efficient, battery operated, portable diagnostic tools and point-of-care devices. Use of acoustic impedance as a distinguishing quantity eliminates the dependence on the electrolytic, pH or magnetic parameters imposed by other manipulation mechanisms.
