Design and analysis of low-cost high-sensitive surface plasmon resonance-based biosensor

摘要

In this paper, we are going to select low-cost plasmonic material and in accordance with special design structurewhich is economical with respect to high-cost noble metals with respect to conventional structure. We are goingto analyze and compare the sensitivity of different metal with fixed special structure. The optical property ofthe material is size dependent and can be achieved by tuning micro and nanostructure design and selection ofproper 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 sizedmetal nanoparticles have drawn and simulated with nanometer precision for difierent material. The selection ofnanostructure with proper material gives the best trade-off with the noble metal. The low-cost SPR sensor isneeded for society to check pollution and other biochemical property and as biosensors.
