Abstract
Techniques for forming nanoribbon or bulk graphene-based SPR sensors are provided. In one aspect, a method of forming a graphene-based SPR sensor is provided which includes the steps of: depositing graphene onto a substrate, wherein the substrate comprises a dielectric layer on a conductive layer, and wherein the graphene is deposited onto the dielectric layer; and patterning the graphene into multiple, evenly spaced graphene strips, wherein each of the graphene strips has a width of from about 50 nanometers to about 5 micrometers, and ranges therebetween, and wherein the graphene strips are separated from one another by a distance of from about 5 nanometers to about 50 micrometers, and ranges therebetween. Alternatively, bulk graphene may be employed and the dielectric layer is used to form periodic regions of differing permittivity. A testing apparatus and method of analyzing a sample using the present SPR sensors are also provided.
