|Title:||SURFACE PLASMON RESONANCE BASED SENSORS UTILIZING GRATING COUPLER|
|Keywords:||PHYSICS;GRATING COUPLER;PLASMON RESONANCE;BIOSENSORS|
|Abstract:||The use of surface plasmon resonance (SPR) biosensors is increasingly popular in fundamental studies, health science research, drug discovery, clinical diagnosis, and environmental and agricultural monitoring. SPR allows for the qualitative and quantitative measurements of bimolecular interactions. Now days, the development of SPR is geared toward the design of compact, low-cost, and sensitive biosensors. Rapid advances in micro-fabrication technology have made available integratable opto-electronic components suitable for SPR. The SPR effect can be observed by use of prism couplers, diffraction gratings and specially configured optical fibers. For purpose of minimizing the cost of fabricating media that support SPR effect. We investigated the feasibility of using a recordable compact disk for observation of the SPR based sensors development. Theoretical Analysis by Finite Difference Time Domain (FDTD) of the silver coated recordable compact disks (CD-R) with different configuration parameter. Angle and wavelength interrogation for structure are presented in this thesis. Experimental analysis of an available gold coated CD is also studied. Higher sensitivity and resolution obtained in results proves potential applications of SPR sensors for bio-sensing and air pollution monitoring.|
