Detecting Benzene Vapor via a Low-Cost Nanostructured TiO₂ Sensor

A vapochromic dye/graphene coated long-period fiber grating for benzene vapor sensing

“…For instance, semiconductive benzene sensors operate at high temperature; gas chromatography and mass spectrometry can detect benzene with high sensitivity, but the efficiency is low thus not conducive to real-time and on-site detection. [7][8][9][10][11] There is an urgent need to develop new benzene sensors for practical applications. Innovations in material engineering, such as the study in new sensitive materials, and device engineering such as developing novel sensing structures, both contribute to developing the benzene vapor detection.…”
