The enhancement unit includes a nanongrid having a plurality of nanogaps. A gas is coupled to the enhancement unit and is configured to flow through the plurality of nanogaps of the nanogrid. The nanogrid comprises one or more plasmon-active materials. The light source is configured to generate plasmon-enhanced electric fields in the plurality of nanogaps of the nanogrid to induce enhanced Raman scattering of the constituent molecules in the gas within the plurality of nanogaps such that a plurality of different constituent molecules in the gas can be detected. In one embodiment, a molecule in the gas is configured to scatter the light from the light source at a rate more than 1000 times greater than in the free space in the enhancement unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-gas detection system and method","description":"A Raman multi-gas detection system including an enhancement unit coupled between a light source and a detector.
