%X Etched fiber Bragg grating (EFBG) was coated with diphenilalanine nanotubes (DNT) to produce sensors capable of detecting methanol in methanol-ethanol blend vapors. The DNT was studied in two phases, hexagonal and orthorhombic, which were observed by Raman spectroscopy and scanning electron microscopy (SEM). The temperature transition between the phases was determined through small angle x-ray scattering (SAXS). Considering the methanol concentration in the vapor, the orthorhombic phase showed a sensitivity of -7.3 ± 0.8pm / (
