Highly-branched plasmonic nanostructures are interesting substrates to be exploited in Surface- Enhanced Raman Scattering (SERS) detection, as sources of efficient Raman ‘‘hot-spots”. In this study, L-cysteine is proposed as reducing/capping agents for the production of Ag nanonets showing different morphologies by varying the synthesis conditions. Substrates are coupled to PDMS membranes and characterized by Raman spectroscopy using 4-MBA to define their SERS performance. Experimental evidences confirm that only the thinnest structures are able to guarantee significant SERS responses.
