In this work, graphene-based metasurface infrared biosensors are presented. The C-shaped tungsten metasurface is placed over graphene material to achieve higher sensitivity. The sensitivity of biosensors depends on how the absorption peak is shifted by the addition of biomolecules over the sensor. T...
