Acoustic plate modes (APM) on various quartz substrates have been investigated in order to determine their usefulness for liquid-sensing applications. The modes have been characterized in terms of their mass sensitivity, mode separation, temperature sensitivity, and reproducibility of the experimental results. Promising characteristics are found for rotated Y-cuts of quartz with the direction of acoustic mode propagation being perpendicular to the X-axis of the quartz crystal. Experiments on the detection of immunochemical reactions are performed using different quartz APM sensors, and the results are compared to similar experiments utilizing APM devices on ZX-LiNbO3.
为了确定各种石英衬底上的声板模式（APM）在液体传感应用中的实用性，对其进行了研究。这些模式已根据其质量灵敏度、模式分离、温度灵敏度和实验结果的可重复性进行了表征。对于石英的旋转Y切型，发现了有前景的特性，其声模传播方向垂直于石英晶体的X轴。使用不同的石英APM传感器进行了免疫化学反应检测实验，并将结果与在ZX-LiNbO3上使用APM器件的类似实验进行了比较。
