The explanation of the mechanism of smell seems somewhat implausible, but, yes, there are a variety of ways one could make a nanoscale IR spectrometer. Another option would be to look for resonant energy transfer, not between a tunnelling electron, but between a vibrational excitation in another molecule and the test molecule.
