  1. So if they extract DNA from the print, they can also narrow it down by gender if there is no hit on CODIS. But does this test dilute the DNA? According to the article, they are not done. They want to use prints to determine if “the person was young or old, male or female, and their ethnicity,” Dr. Halamek said.

    Fascinating. It will not be long before ID is determined in a traffic stop by an instant DNA check.

  2. I would think that this test would not dilute the DNA since it is only measuring amino acids in the fingerprint residue. It’ll be interesting to see if Dr. Halamek is able to determine those other characteristics, including age and ethnicity, from residue left behind by fingerprints, or whether, since he’s currently using protein markers found in blood samples, an actual DNA sample will have to be left behind; then also, concerns may arise about competing uses for DNA. Something closer to the subject of using DNA to determine ethnicity, age, and gender is Genomics, which was recently written on in the Huffington Post:
