Plug microvalve integrated device for rapid and portable qualitative TNT detection.129 (a) Device photograph where fluorescent silica nanoparticle and TNT solutions were introduced by the two inlets. Mixing of TNT and nanoparticle solutions leads to fluorescence quenching in the test channel. (b) Device tested with TNT solution under 366 nm excitation. (c) Control assay run with water.
