Highly Sensitive Bimetallic Graphene- Based SPR Biosensor for Blood Plasma Detection
This research proposes a highly sensitive biosensor utilizing bimetallic surface plasmon resonance (SPR) technology for detecting blood plasma concentration which consist of a BK-7 prism, Au (25 nm), Ag (20nm), BatiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>(5 nm), Graphene (3L*0.34nm) and a biosample. To increase the sensitivity a dielectric material BaTiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>is introduced between bimetal and graphene layer. With optimized layer parameters the proposed sensor shows enhanced sensitivity of 220°/RIU as compare to the single metal structure.
