Abstract
In this study, a surface plasmon resonance biosensor at near infrared frequency based on a metamaterial is proposed. The proposed biosensor utilizes the properties of plasmons and metamaterial for enhancement of its performance parameters i.e. sensitivity, detection accuracy and quality factor. The thickness of the metamaterial and gold film has been optimized for optimal performance of the proposed biosensor at near infrared wavelengths. Results obtained from the proposed biosensor were compared with existing two-dimensional nanomaterials such as a graphene based biosensor and a conventional surface plasmon resonance biosensor. Finally, it is observed that the performance parameters of the proposed biosensor are very high when compared to existing surface plasmon resonance biosensors.
