Tuning and Sensitivity Enhancement of Surface Plasmon Resonance Biosensor With Graphene Covered Au-MoS 2-Au Films
In the conventional surface plasmon resonance biosensor, the sensitivity using angular interrogation is low. Graphene/MoS<sub>2</sub> has been attached on the metal surface to improve the sensitivity; however, the ability to improve sensitivity is limited. Here, by sandwiching the MoS<...

| description | In the conventional surface plasmon resonance biosensor, the sensitivity using angular interrogation is low. Graphene/MoS<sub>2</sub> has been attached on the metal surface to improve the sensitivity; however, the ability to improve sensitivity is limited. Here, by sandwiching the MoS<sub>2</sub> sheets between two gold films in the Kretschmann configuration, we demonstrate an ultrasensitive surface plasmon resonance sensor. By optimizing the structure of sensor, we find that the sensitivity as high as 182°/RIU can be realized with 4-layers MoS<sub>2</sub> and a monolayer graphene. Moreover, it is indicated that the sensitivity can be tuned and controlled by changing the layer numbers of graphene and MoS<sub>2</sub>. |
