. Additionally, a 10−6 mol·L−1 solution of lysozyme was successfully detected using the Mg–Au nanopore substrates. Our low-cost method is reproducible, homogeneous, and suitable for the fabrication of SERS substrates.

Surface-enhanced Raman spectroscopy (SERS) can be used to detect biomolecules [1][2][3], explosives [4][5][6], and pesticide residues [7][8][9]. Plasmonic metal nanostructures are often used as SERS substrates to increase the molecule-specific
