摘要
The characteristics of Love wave biosensors are systematically investigated.The results show that sensors with combination of a ZnO guiding layer and 90ST or 90AT Quartz substrates exhibit purer Love modes than those with the SiO 2 guiding layer.The corresponding maximum sensitivities are -10.9069and -11.641 m 2 /kg, respectively, which are nearly two times higher than those of SiO 2 layer.The ZnO/90ST Quartz Love wave sensor exhibits the largest K 2 of 0.3022 and achieves 0 ppm/ • C of TCF at h ZnO /λ = 0.0216.The sensor employing the graphene IDT further improves the sensitivity by nearly one order of magnitude.
