Surface acoustic wave (SAW) devices have been utilized for the sensing of chemical and biological phenomena in microscale for the past few decades. In this study, SAW device was fabricated by electrospinning poly(vinylidenefluoride-co-trifluoroethylene) (P(VDF-TrFE)) incorporated with zinc oxide (ZnO) nanoparticles over the delay line area of the SAW device. The morphology, composition, and crystallinity of P(VDF-TrFE)/ZnO nanocomposites were investigated. After measurement of SAW frequency response, it was found that the insertion loss of the SAW devices incorporated with ZnO nanoparticles was much less than that of the neat polymer-deposited device. The fabricated device was expected to be used in acoustic biosensors to detect and quantify the cell proliferation in cell culture systems.

通过静电纺丝 P(VDF-TrFE)/ZnO 纳米复合材料降低插入损耗的表面声波器件。

过去几十年来,表面声波(SAW)设备已被用于微尺度化学和生物现象的传感。在本研究中,SAW 器件是通过在 SAW 器件的延迟线区域上掺入氧化锌 (ZnO) 纳米颗粒的聚偏二氟乙烯-三氟乙烯 (P(VDF-TrFE)) 静电纺丝来制造的。研究了 P(VDF-TrFE)/ZnO 纳米复合材料的形貌、组成和结晶度。测量SAW频率响应后,发现掺有ZnO纳米颗粒的SAW器件的插入损耗比纯聚合物沉积器件的插入损耗小得多。所制造的装置预计将用于声学生物传感器,以检测和量化细胞培养系统中的细胞增殖。
