There's an ongoing trend in miniaturizing optical spectrometers [1]. MEMS-FTIRs should have interesting application in air analysis [2,3].

Real-time gas measurements are quite routine and mandatory in industry [4]. Wider spread of analytical chemistry technology to consumers will lead to a better world - pregnancy tests, insulin meters, breathalyzers are just the beginning :)
