Claim:
1. A method of fabricating a sensor having a metamaterial comprising split-ring resonators operable in the visible-infrared range, the method comprising a) depositing a layer of a conductive material on a non-conductive flexible substrate; b) forming a layer of electron beam resist on the layer of conductive material; c) patterning the layer of electron beam resist using electron beam lithography to form a patterned substrate; d) depositing a layer of a noble metal on the patterned substrate; and e) removing the resist to generate the metamaterial comprising the split-ring resonators having a least line width of about 20 nm to about 40 nm on the non-conductive flexible substrate.
