Abstract: An innovative surface plasmon resonance (SPR) approach for the detection of 2,4,6-trinitrotoluene (TNT) gas traces, obtained using an engineered molecular imprinted sol-gel film as recognition layer onto a plasmonic gold grating, is here proposed. The SPR substrate combined with the sol-gel matrix is able to trap gas phase TNT molecules from a TNT-saturated environment (4.9 ppb). Taking advantage of the azimuthally-controlled grating-coupled SPR, this sensing platform demonstrates the potentiality to detect TNT traces < 1 ppb with a sensitivity of 0.47 °/ppb
