论文摘要
我们已经采用了单金属金属和多层AG/SI3N4/AU等离子传感器来监视葡萄糖/水溶液的折射指数的变化。我们的结果表明,传感器可以解决葡萄糖折射率降低至1%的浓度。此外,我们通过使用COMSOL的有限差方法模拟了表面等离子体共振的Evanescent电场的强度。 AG/SI3N4/AU传感器的电场强度远比单金层SPR传感器强得多。
We have employed single gold layer metal and multilayer Ag/Si3N4/Au plasmonic sensors to monitor changes in the refraction index of glucose/water solutions. Our results show that the sensor can resolve glucose refractive index down to 1% concentration. In addition, we have simulated the strength of the surface plasmon resonance evanescent electric fields by using the finite difference method of COMSOL. The electric field strength for the Ag/Si3N4/Au sensor is much stronger than that for single gold layer SPR sensor.
