In this paper, we are going to select low-cost plasmonic material and in accordance with special design structure which is economical with respect to high-cost noble metals with respect to conventional structure. We are going to analyze and compare the sensitivity of different metal with fixed special structure. The optical property of the material is size dependent and can be achieved by tuning micro and nanostructure design and selection of proper material. Due to change in optical property of macro and nano scales structure properties of materials, we can achieve for low-cost material with high-performance SPR sensor. Optical properties of submicron sized metal nanoparticles have drawn and simulated with nanometer precision for different material. The selection of nanostructure with proper material gives the best trade-o_ with the noble metal. The low-cost SPR sensor is needed for society to check pollution and other biochemical property and as biosensors.
