  Hybrid Techniques in Fingermark Visualization: Combining Spectroscopic and Chromatographic Methods for Complex Substrates
  Author(s): Saleh Mansour*
  
  Speculations have been made for some time as to what might happen if hybrid techniques were used in conjunctions to enhance fingermarks. The main consideration to date has been imaging, but there appears to have been no studies of the effects of using spectroscopic techniques on a fingermark that has been developed using a chromatographic technique. This is a significant omission as it is likely that the chemical additives inherent in some substrates would confound the spectral information obtainable from the sebaceous components of a fingermark. Four selected chromatographic techniques, Cobalt-2, Ninhydrin, Sticky Side Powder, and Vacuum Metal Deposition, were used to develop fingermarks on substrates containing chemical additives. Apart from Derek (Cobalt 2), a dark grey background, most of the chemical additives used were either at- or near-IR fluorescent. Fingermarks d.. Read More»
