Fingerprints are used as individualizing evidence. However, they cannot be analyzed when prints are badly smudged or distorted. Hence, several studies have demonstrated the feasibility of DNA profiling from fingerprints and it was proven that they could become a potential source of DNA for personal identification.In this study, we compared two collection methods - “cut to pieces” or “swabbing” for STR genotyping from fingerprints on common office papers by three commercially available extraction and the effects of 1,10-phenanthroline (L) as ligand molecule treated to fingerprints in order to minimize DNA degradation by various metal ions (M) which are the components of sweats on fingerprints has also been demonstrated. This study shows that the “cut to pieces” collection is an efficient method for extracting DNA from paper and treatment of 1,10-phenanthroline to fingerprints has a tendency to provides more correct alleles compared to other samples, Therefore, further examinations have to be required.
