Abstract:

We have developed a simple, effective, and user- and environmentally friendly fingermark detection method using chloroform extracts of Vitis vinifera L. leaves and Solanum melongena L. peels as fingermark reagents. The method is based on the reactions of phenolic compounds and anthocyanins in these plants with amino acids, which are an important component of fingermark residue. The extract solutions reacted with latent fingermarks on copier paper to give photoluminescent prints when illuminated at 515 nm viewed through red filter. Comparison to 1,8-diazafluoren-9-one (DFO) indicated that the Solanum melongena L. peels extract could be an alternative to existing methods like DFO.

Keywords: Latent fingermark; Anthocyanin; Solanum melongena L.; Vitis vinifera L.; DFO
