单金属Au和Ag/Si3N4/Au等离子体传感器用于葡萄糖refractive index测量

Application of single metal Au and Ag/Si3N4/Au plasmonic sensors for glucose refractive index measurements

Hussein Akafzade, Nader Hozhabri, Suresh C Sharma

摘要:

我们采用单层金层金属和多层Ag/Si 3 N4/Au等离子体传感器来监测葡萄糖/水溶液的折射率变化。我们的研究结果表明,传感器可以解决葡萄糖折射率低至1%的浓度。此外,我们还利用COMSOL有限差分法模拟了表面等离子体共振瞬态电场的强度。Ag/Si 3 N4/Au传感器的电场强度比单层金SPR传感器的强得多。

英文摘要:

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.
