The trace level detection of explosive compounds is a rapidly evolving field of crucial interest for environmental safety and homeland security. In this frame, surface-enhanced Raman spectroscopy (SERS), has gained increasing importance because, since its first observation, the surface enhancement effect promised to overcome the problems arising from the low sensitivity of Raman spectroscopy, combining its analytical advantages with the possibility of trace level detection. The results, discussed in application note, validate the use of the SERS technique with a lower cost compact Raman platform for in-field security diagnostics.
