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