Abstract
We have reported a novel design of Surface Plasmon Resonance (SPR) device, which uses alternative dielectric layers to enhance the SPR signal quality and modulate its resonant position. Admittance loci method of thin film design has been used in the design of such a device. The fabricated device results in a calibration curve, y= 0.124x + 62.39 (R2=0.99) of different glucose concentrations.
