An ultra-sensitive explosive detector inspired by a butterfly

published on , updated on

The teams of NS3E and the LMSPC (Strasbourg) have created one of the most sensitive explosive detectors in the world, based on an AFM microcantilever covered with titanium dioxide nanotubes. This system is inspired by the sensillas of the silkmoth, bombyx mori.

These results have been published in the journal Angewandte Chemie. The article is available in English and in German.
