Dye-modified silica–anatase nanoparticles for the ultrasensitive fluorogenic detection of the improvised explosive TATP in an air microfluidic device Lapcinska, Sindija Revilla Cuesta, Andrea Abajo Cuadrado, Irene Cuevas Vicario, José Vicente Avella, Manuel Arsenyan, Pavel Torroba Pérez, Tomás Química Chemistry We describe the proof of concept of a portable testing setup for the detection of triacetone triperoxide (TATP), a common component in improvised explosive devices. The system will allow field-testing and generation of real-time results to test for TATP vapor traces in a number of different environments. It will work by recirculating the gas samples in connection to the sensing mechanism in a suitable microfluidic portable device. In this way, the system will allow controlled trapping of the analyte in the chemical sensor to afford reliable results at very low concentrations in air.
