Detection of explosives on human nail using confocal Raman microscopy
Trace amounts of explosives were detected on human nail using confocal Raman microscopy. Contamination of the nail can result from the manual handling, packaging or transportation of explosive substances. Raman spectra were obtained from pentaerythritol tetranitrate (PETN), trinitrotoluene (TNT), ammonium nitrate and hexamethylenetetramine (HMTA) particles on the surface of the nail with dimensions in the range 5–10 µm. An added ... Read more

Raman spectroscopy and security applications: the detection of explosives and precursors on clothing

Raman spectroscopy and security applications: the detection of explosives and precursors on clothing
This study describes the application of confocal Raman microscopy to the detection and identification of explosives and their precursors _in situ_ on undyed natural and synthetic fibres and coloured textile specimens. Raman spectra were obtained from explosives particles trapped between the fibres of the specimens. The explosives pentaerythritol tetranitrate (PETN), trinitrotoluene (TNT), and ammonium nitrate as well as the explosives ... Read more
