Claim 0:
1. A Raman multi-gas detection system having an enhancement unit coupled between a light source and a detector wherein the enhancement unit includes a nanogrid having a plurality of nanogaps, wherein the nanogrid has a first side and a second side, wherein a gas having constituent molecules to be detected is configured to enter the nanogaps of the nanogrid on the first side of the nanogrid, wherein the nanogaps of the nanogrid are configured having plasmon-enhanced electric fields, and wherein the gas is configured to exit the nanogaps on the second side of the nanogrid such that constituent molecules in the gas are configured to undergo enhanced Raman scattering as they pass through the plasmon-enhanced electric fields of the nanogaps of the nanogrid.
