Experimental workflow of the ML-SERS platform. (a) Rhodamine 6G was used as a SERS reported molecule on plasmonic Moxtek (1) or Plasmore (2) substrates. Varying solutions of R6G were pipetted (~20 µL total) onto the surface and 20 × 20 pixels surface areas were scanned. (b) SEM micrographs illustrate the structure of the Moxtek and Plasmore substrates. (c) Representative SERS spectrum of R6G; the highlighted peaks at 620, 780, 1198, 1367, and 1513 cm⁻¹ are characteristic spectral features of R6G.
