The purpose of this work is the attribution of gunshot residue (GSR) to manufacturer using Surface enhanced Raman Spectroscopy enabled by a bench top portable spectrometer. We propose nanostructures that span zero- (metal and magnetic clusters), one- (rods), and three- (microbars) dimensions, synthesized in our laboratory. These substrates are chosen because they have charge transfer capabilities with the organic analytes present in the GSR or electromagnetic field enhancements to provide a basis for this approach. This study presents the LOD measurements of the SERS signal from diphenyl amine and ethyl centralite with the gold and silver nanoparticles.
