The ISOGAL survey discovered a population of narrow (down to 10 arcsec in size) absorbing filaments and globules which appear as dark features in the 7 μm and 15 μm plates. These infrared dark clouds turn out to be the highly condensed parts of Giant Molecular Clouds (GMC's) kiloparsecs away from the Sun. We report here follow-up observations at radio-mm wavelengths conducted at the IRAM 30-m telescope, and present the first results of the physico-chemical analysis of the gas associated to the dense dust revealed in mid-IR.
