Posted: Dec 10, 2008 12:15 pm Post subject: Fingerprints Can Reveal Drug Use, Medical History |
|
|
From Discovery News: http://dsc.discovery.com/news/2008/12/10/fingerprint-drugs.html
The new technique attaches the iron oxide particles to antibodies and suspends them both in a liquid solution, which is then drizzled over a fingerprint. If the chemical that a specific antibody targets is present, the molecules latch onto it and glow.
So far the scientists can detect five different drugs: THC (marijuana), cocaine, nicotine, methadone and a derivative of methadone. Other drugs, particularly opium-based drugs like heroine or morphine, should also be detectable, since antibodies already exist for them as well.
Drugs aren't the only chemicals the new tests could detect. Cancer, diabetes, heart disease and other medical conditions produce specific chemicals also secreted in sweat and oil. By tweaking the antibodies on the particles, forensic scientists could test for a variety of medical conditions. This could help police track down a suspect by, say, watching the local kidney dialysis clinic if the suspect has kidney failure.
On the other side, prosecutors could also use additional fingerprint information to convict criminals, or defenders could use it to help keep clients out of jail. If a fingerprint has the antibodies for, say, a genetic disease that a client doesn't have, a defender could use that information to raise doubts about the prosecutor's case.
On the flip side, what ethical issues may arise from this technology?
More from the article: The technique will certainly help police gain more information about criminals, but there are privacy concerns for law abiding citizens, said Cooks.
"If I come to your office and leave a fingerprint on your desk, you now have a biomedical sample of me," said Cooks. "You can then proceed to find out as much information about me as you want," from what lotion you used that morning to what drugs you did last night. _________________ chance favors the prepared mind |

I assume it's like anything else... hair and blood and urine samples... it eventually won't show up, but the article didn't discuss timeframes. _________________ chance favors the prepared mind |

LFdisciple, hair will retain THC and show how often youve smoked for the length of the time that hairs been there, could work for other drugs to but haven't heard of it _________________

jeff knox - you have to cut off all of your hair
weed shows up on any hair on your body
but there are special shampoos that actually work
my little bro's HS dose random testing and so my mom got him the shampoo and he passed. so my parents hung his paperwork on the fridge . lol _________________ https://vimeo.com/moontowerco |
