Abstract
A gas conduit directs a flow of gas from a gas flow source. A surface enhanced luminescence (SEL) stage is within the conduit and includes a substrate and nano fingers projecting from the substrate. A heater heats the nano fingers to a temperature so as to soften the nano fingers such that the nano fingers collapse towards each other to capture molecules entrained in the gas therebetween.
