In this study, we introduce an inexpensive and a novel 3D printing process using the electrohydrodynamic jet printing methodology. A wide variety of controlled silver nano islands and nano lines have been printed to measure plasmonic response to fabricate cheaper and faster Surface-Enhanced Raman Scattering (SERS) sensors. The jetting parameters have been developed to control the size, shape and periodicity of the nano metallic patterns. These structural differences are compared with the changes in SERS measurements comprising of both localized and propagating surface plasmons. The above printing process can be used to create a highly ordered, 3 dimensional, multilayered, plasmonic platforms to enhance the electromagnetic hotspots for high SERS enhancement factor (EF). Such a platform can also be used to detect multiple species in chemical, biological and optical sensors on the same platform.
