Abstract

We demonstrate the fabrication and characterization of an array of plasmonic metamaterial nanostructures based on asymmetric split H (ASH) resonators on a zinc selenide substrate that produce plasmonic resonances matched with the molecular vibrations of an organic material. Estrogenic hormones; 17β-Estradiol (E2) and Estrone (E1) were chosen as analytes for coupling with the plasmonic resonances. The experimental results show there is a good match with the molecular bond resonances of the C-H, C=O and C=C observed in estrogen and we have also shown that it is possible to differentiate the molecular bond resonance spectrum of E2 in a mixture with E1.
