This paper compares plasmonic substrates manufactured by three lithography methods: E-beam. soft and hard UV NanoImprint Lithography. The different plasmonic modes existing in samples made of an array of gold nanostructures on gold film are investigated for biochemical detections taking advantage of Surface Plasmon Resonance Imaging (SPRI) and Surface-Enhanced Raman Scattering (SERS).... https://www.roneverhart.com/SAAB-9-3-I-98-02-Frontlykt-Hoyre/
