This paper presents new experimental results on the sensitivity of a microstructure fiber (MSF) to toluene and ethanol in gaseous mixtures with nitrogen. This sensitivity is compared with that determined with a single-capillary fiber (CF). The results obtained both with the fibers modified by a porous detection layer prepared by the sol-gel method from tetraethoxysilane are presented. MSF with air holes arranged in one shell and coated with an UV acrylate jacket was prepared by using the "stack and draw" technique. CF coated with polydimethylsiloxane optical cladding was prepared.
