Nitrogen dioxide optical fibre sensor based on nanoporous glass probe was obtained. As a sensor probe glasses from the Na2O-B2O3-SiO2 system modified with TiO2 and ZrO2 and Al2O3 have been made. Porous glasses based on silica posses very good thermal and chemical durability, they are also transparent in the wide of spectrum range. It makes also possibility of use this kind of material as an optical sensor element, operating in hard working conditions. The presented design consists in the spectroscopic changes caused by the specific coloration reactions between NO2 and organic reagents placed in the nanopores. The presented different sensing reagents are compared and allow to achieve ppb NO2 level detection. High specific surface area (200 m2/g) and stable pores distribution in the size of obtained glasses assured good repeatability of the sensor.
