摘要 The mass sensitivity of a layered surface acoustic wave (SAW) device,ZnO/36°LiTaO_3,has been studied.Gold layers of different thicknesses were deposited to form the protein-sensitive layer,in order to compare the responses to biological materials and to find the optimum thickness of the gold thin film.Sensitivity of the device was investigated by immobilization of lactate dehydrogenase (LDH) onto the device active area.

Sensitivity of the device was investigated by immobilization of lactate dehydrogenase (LDH) onto the device active area.
