A chemical sensor based on polymer nanostructures can detect nerve gas at concentrations as low as 10 parts per trillion (Nano Lett., DOI: 10.1021/nl204587t). With further development, the flexible sensor materials might enable wearable systems for detecting chemical weapons, the researchers say.

Currently, soldiers and police use mass spectroscopy-based devices to detect organophospates, the group of compounds . . .
