 New fingerprint method can spot drugs or explosives

New fingerprint method can spot drugs or explosives
August 7, 2008 - telegraph.co.uk
Fingerprints could be used to detect traces of drugs or explosives in one of the most significant improvements in the technology for years.
 Police now have the ability to analyse the traces of cannabis, cocaine and other drugs, or explosives, in a fingerprint itself.
The new technique reveals, in extraordinary detail, the chemical compounds that make up the print and could also find medical uses, since tiny traces of chemicals at our fingertips could signal the presence of a disease or an illness.
This method can also be used directly on a fingerprint, right where it's found, without the need to lift the print off and take it to a lab for analysis.
Dr Demian Ifa, Prof Graham Cooks at Purdue University in West Lafayette, and colleagues report in the journal Science how they used a technique called desorption electrospray ionization, or DESI, which involves spraying a solvent onto a fingerprinted surface and then analysing the droplets that scatter off the print with a method called mass spectroscopy.
The technique provides a "chemical image" of the fingerprint with higher resolution than other techniques, and can analyse as little as a billionth of a gram of material, said Prof Cooks.
"The classic example of a fingerprint is an ink imprint showing the unique swirls and loops used for identification, but fingerprints also leave behind a unique distribution of molecular compounds," Prof Cooks said. "Some of the residues left behind are from naturally occurring compounds in the skin and some are from other surfaces or materials a person has touched."
In this way, the researchers can detect minute traces of compounds - marked as dots on the print - that were on the fingertips of the person who left the print.
This technique can pick up small amounts of drugs like cocaine or THC, the active ingredient from marijuana, as well as compounds from explosives.
Researchers may also find this technique useful for identifying metabolites or other compounds in fingertip secretions, whose presence may signal other processes happening inside the body.
The team is also studying if it could be used as an alternative to blood and urine tests for athletes, said Prof Cooks.
The image can also be analysed with standard fingerprint imaging software to try to identify that person and help distinguish overlapping prints."Because the distribution of compounds found in each fingerprint can be unique, we also can use this technology to pull one fingerprint out from beneath layers of other fingerprints," Dr Ifa said.
"By looking for compounds we know to be present in a certain fingerprint, we can separate it from the others and obtain a crystal clear image of that fingerprint. The image could then be used with fingerprint recognition software to identify an individual."

This a joke. 40% of money contains trace amounts of drugs, there is no way there is going to hold up.

Funny thing, a couple of friends and I were talking about money the other day... Around here it seems like they are trying to do away with physical currency altogether. I'm seeing a push you move all money into a purely electronic format. I'm kinda worried about how I'll buy weed, etc when all I have is a debit card.... off topic a little but what the hell, I'm glowin'!!!

no way, itll never happen, theres too much risk in having purely electronic funds, people wont let that happen i dont think.
but does this mean that they have a new fool proof drug test system for cannabis? that would suck.

as long as republicans are in office, then we are going to see a push towards policed states, no actual freedoms among the people, and more lives and families destroyed from the "war on drugs".
I know i've posted in the past supporting eradication of poppy and coca. I'm not a republican. I think this fingerprint crap is intrusive, and will be abused.
I hate the government now, it used to be cool... technology is making it impossible to have certain freedoms.
I miss the cold war reagen era when pot was schedule 5, and punk rock kicked ass, and people weren't so intrusive into personal lives, back when "what people do behind closed doors" meant something.
Now, all of our lives are exposed, and it's only going to get worse.
Ultimately society is going to want a "purist society" where there are no criminals, drugs, or freedom.
reminds me of an old sci fi movie...

bullshit. If they introduced it in drug testing, someone would come up with a counter. technology can work both ways

yeah this is bullshit, on top of having touched money and tested positive for 30 drugs, one may touch a pack of matches and test positive for terrorist.
welcome to prison, heres your butt-plug, enjoy your stay.

I bet some people said the same thing when Lincoln was trying to get everyone to give up their gold and silver in favor of paper currency .
The Constitution states ' Article 1, Section 10, Clause 1 says that No State shall...make anything but gold and silver coin a legal tender in payment.
And yet we have this worthless paper money which is just as risky as having electronic funds. When the economy tanks and the dollar falls you might as well just use that paper to wipe your ass. It will be worth nothing. but gold and silver will be so which would you rather have paper or gold and silver that can be used any where in the world?

this is how the system generates cash!
also, i think i recall somewhere reading that by the next ten years over half the US residents will actually be incarcerated .

the greenback used to just represent gold and silver, you could trade them in for its value in gold and silver, but then they did away with that, that is when we became an electronic system, and the credit crises started. Everything became electronic, so if someone created more, and no one knew better you could just have more, especially when it is controlled by one asset, so then money is just created where none exists. though i would still rather have cash over plastic any day, because while it is still pretty much worthless in certain times, it requires no electric to exchange, so it is one less level of control over my money. And it is the most widely accepted form of payment.
but being able to know what is on your fingertips would really bother me. What if i just happened to touch a door handle someone who just touched it did, or shook the hand of someone who had some drug on them, and it somehow got on the fingerprint, what is to say it really was something from me, or something else. Plus people touch the ground way to many times in a day for there to be no residue anyways.

Heh, the system could be broken relatively easy, just start shaking everyones hand after rolling a J, and start rubbing illegal droogs on the money you spend....
"New system introduced, 700,000 Americans arrested."
--------------------
God takes those closest to us, because it makes him feel better about himself. He is a very vengeful God. He's all pissed off about something we did thousands of years ago. He just can't get over it, so he doesn't care who he takes. Children, puppies, it don't matter to him, so long as it makes us sad.
Why does God give us anything?
Look at it this way: if you want to make a baby cry, first you give it a lollipop. Then you take it away. If you never give it a lollipop to begin with, it would have nothin' to cry about. That's like God, who gives us life and love and help just so that he can tear it all away and make us cry, so he can drink the sweet milk of our tears. You see, it's our tears, Stan, that give God his great power.
