Paper Abstract
Zeolite-coated cantilevers provided with internal heating elements have been developed and used for the selective
detection of nitroderivates, in particular o-nitrotoluene as an example of an explosive-related molecule. In particular, Co
exchanged commercial BEA zeolites have been deployed of rectangular Si cantilevers by microdropping technique. In
particular, two different strategies have been demonstrated to increase the zeolite modified cantilevers performance: the
sensing coating and the operating temperature. As a result, o-nitrotoluene LOD values below 1 ppm are attained at room
temperature conditions; whereas the interference of toluene at concentrations below 1000 ppm is completely suppressed
by heating the cantilever.
