Abstract :
In recent years, explosive based terrorism has grown enormously; moreover, chemical warfare is forecasted as the next terror inflicting agents. Detecting such materials is a challenging task. Aiming towards "artificial nose", we take advantage of highly sensitive porous silicon microcantilevers devices in combination with non specific polymer layers and monitor their interaction with target analytes. Our screening method is through passive and active modes of detection and has been proved effective for distinguishing between different isotopically labeled substances.
