Abstract: A system for detection of low concentration of explosives via Raman spectroscopy is disclosed that is more specifically a Raman detection substrate having a surface-enhancement effect by using roughened glass (or “frosted” glass) with a gold/silver nanosponge alloy sputter-deposited onto it under increased pressure resulting in a nano-porous structure to hold the analyte.
