| description | This study presents a SPR biosensor based on angular interrogation to get the significant figure of merit (FoM) by means of aluminium doped zinc oxide, dielectric, and graphene. Graphene is used here as an interaction layer with the sensing medium due to its larger surface area for binding of biomolecules. SPR biosensor’s performance parameters for aluminium doped zinc oxide-based SPR sensor is compared with conventional SPR sensor that utilize metal for plasmon generation. The maximum FoM of 426.1 RIU−1 is acquired for the proposed SPR sensor design using AZO and dielectric having 3000 nm thickness. Hence, proposed theoretical work would be practically suitable for biosensing with high accuracy and quality in near future with available fabrication technique. |
