With the help of the EXIST research transfer the startup True Detection System (TDS) will develop a portable and easy-to-use handheld device based on chemical-optical sensors that can detect the smallest traces of various explosives and markers (e.g. TNT, C4, ANFO, TATP, DMDNB, etc.) and pure salts (e.g. potassium nitrate) reliably and without major cross-sensitivities. The device has been developed over the last 10 years at the Federal Institute for Material Research and Testing (BAM) in cooperation with an SME. Within the next 18 months, a laboratory prototype will now be converted into a commercial device.
The development of a Lab-on-a-Chip (LoC) is presented, which can detect reactive phosphorous compounds in the gas phase in combination with an optochemical hand-held sensor. The LoC prototype contains three pairs of sensing materials containing fluorescent indicator dyes in various carrier materials. By measuring the fluorescence response to phosphoryl chloride, a surrogate compound, the detection of chemical warfare agents (CWAs) in gas phase becomes possible within seconds, introducing a novel approach to CWA detection.
