Abstract: Methods are provided for making a membrane or textile having a mechanically robust surface-enhanced Raman spectroscopy (SERS) substrate by in a first step adhesively bonding a micropatch array to a substrate, the micropatch array having a plurality of micron-scale pillars, each of the micron-scale pillars in the plurality of micron-scale pillars containing a plurality of plasmonic nanoparticles dispersed within a polymer matrix; and in a subsequent step etching a portion of the polymer matrix to expose at least a portion of the plasmonic nanoparticles at or near a surface of the micron-scale pillars. Membranes and textiles containing the mechanically robust surface-enhanced Raman spectroscopy (SERS) substrates are also provided.
