Cocaine Biosensor
Aaron Rowe writes "The MIT Technology review reports that a lab at UC Santa Barbara has created a biosensor by attaching a special type of DNA called an aptamer to a gold electrode. When cocaine is present, the aptamer tightly hugs a cocaine molecule and leans over so that a metal tag can touch the gold surface. This causes a spike in a plot of current versus voltage when the electrode is attached to a machine called a cyclic voltmeter."
I'm a known gold bug and I've been very interested in the industrial applications of gold (partially to gauge demand issues for future supply). In recent months I've found gold being useful for medicine (possibly as a cancer detector most recently). Now it seems it is useful in finding drugs (although I'm sure this would be only for a police purpose, in a free market the same device might be useful in finding the best drugs).
What are the reasons for gold being used in these situations? I'm very familiar with gold's uniqueness, but it surprises me that it is becoming such a popular metal again -- even beyond the computer and audio industry. Is it really unique for these applications, or is it just a great way for the manufacturers to pad their bottom lines?
Great, there goes my job.
Will these be for sale to the public, I could use one!!
Or does the medical research community not care that my life is made hazardous having to work with sweets-scarfing aspartame junkies??
How they get the coke for testing?
um... officer, it's for "medical research"
crackheads around the USA mourne.
There are already plenty of "instant" drug detection kits, but I wonder what OTHER uses this technology will have?

and seconds after they turned it on, the sensor was activated by a passing UCSB undergrad...

Sounds kinky. Makes me regret not listening during chemistry class.
Don't trust a bull's horn, a doberman's tooth, a runaway horse or me.

There are a lot of "Cocaine biosensors" you could hire off the street for a few dollars ah hour. They will react quite strongly when they find the compound in question (i.e. the "good stuff").
Cocaine's a hell of a drug!
They might as well have named it the $20 bill biodetector.

It has the potential to measure concentrations of thereputic/analgesic drugs too. Imagine an needle with appropriate probes inside which constantly monitor the blood concentration of drugs. Wires lead to an IV control which then administers the drugs at precisely the rate required.
This is, of course, a very hypothetical future - it might not work out this well.

Maybe they could install these in banks and have them thrown out after about 5 minutes because the staff were going nuts about the constant beeping every time they counted $100 bills...

One would hope that this would lead to methods that would be available to employers who currently only test for marijuana. Supposedly cannibus will show up even it it was consumed a month prior, cocaine on the other hand does not show up.
Of course if you look at the history of the CIA in the 80's, one might hypothesize that the government has no interest in stopping cocaine consumption.
At least we all know marijuana is very bad.....there's this new movie out, Reefer Madness......really informative.
Do users get a different type of buzz?? Bet Robert Downey Jr will try to quash this technology ASAP.
As a recent grad of UCSB, i'd have to say they picked the perfect place to develop a cocaine sensor. The students and faculty will have no problem finding suitable substances to test it on.

"attaching a special"... "an aptamer to a gold electrode."... "...the aptamer tightly hugs..." "...and leans over so that a metal tag can touch the gold surface. This causes a spike in a plot of current versus voltage when the electrode is attached to a machine called a cyclic voltmeter."

Have you hugged a cocaine molecule today?
In other news, dogs are arguing that this will eliminate hundreds of jobs, putting many on the street to fend for themselves.
The difficult bit was persuading George W Bush to swap the silver spoon for a gold one.

As soon as the sensor was activated, swat helicopters started circling the place; hidden cameras in the ceiling monitored every move; FDA agents, in cooperation with neighbors, were listening behind the walls.
That's when it hit me: It is time for more Brandy...
"It is the mark of an educated mind to be able to entertain a thought without accepting it."
At-home pregnancy tests are the model of diagnostic simplicity: a tester just pees on a stick and within minutes knows if she has to buy a crib. Imagine if one could just as easily detect HIV infection or a drug overdose.
The real challenge is getting the corse to pee on the stick. I suggest the 'old hand in the warm water' trick.

contamination... physical scraping... oxidation...
I think there is enough dust and grime to mess up this sort of tech in real-world usage.
Now the War on Drugs will *surely* be won in short order!
Any program relying on (nontrivial) preemptive multithreading will be buggy.
Since its pretty common knowledge that roughly 80% of US paper money is contaminated with cocaine, the more cash you carry the more likely the government will bust you as a drug dealer :)
It's only paranoia if your wrong...
It ended up taking about 68 kilos of cocaine to finally nail down the winning formula, reported biochemist George Placky. "We put in a lot of long nights, in fact we frequently would stay in the lab for 72 hours straight." "The team worked so hard we tried to accomodate them wherever possible." Indeed the lab is awash with stereo equipment, couches, and large screen TVs.
Univeristy officials confirmed the long nights. Security guard Paul Costas remakred "Yeah, those guys were going at it for days on end. I helped them smuggle chicks into their parti..ahh *research*."
"We feel that with another couple of years we will have similar sensors for crystal meth, heroin, and extasy." said Dr. Placky, who is currently applying for federal grants to fund the research, as well as provide sufficient quantities of the substances for thorough research.

When asked if the device could register false positives, the researchers responded, "She don't lie, she don't lie, she don't lie; cocaine."
Since when has this country used intellectual elite as a pejorative term?
Are they sure that they've established true causality? Are they sure it's the cocaine?
I volunteer to snort some cocaine (I'll need more than a molecule) and touch a gold surface they've provided if the urge strike me. And I volunteer to keep doing it at 30 minute intervals until all of the cocaine is gone.
All in the interests of science, of course.
I am interested in your 0-day, and would like to offer my services as a Beta Tester.

I can understand the reasons for a business such as home depot needing to test their employees for drug use but I think it's more of an insurance/legality thing for them. It's one of the only stores that I know of that often has a few hundred lbs of moving merchandise on a moving forklift several feet above customers heads. So, I don't want someone who's just done a line at the wheel.
/motor skills test at the beginning of each shift.
But do I feel safer knowing that Home Depot does drug testing?! HELL NO! It's just piss in a bottle and quite often it's origins are not of the piss'er.
Comply with laws, legal requirements and fuck the customer. If they really wanted to ensure that customers didn't get CinderBlockHeadItus then they could subject each employee to a simple peer evaluated sobriety
What a crock. I think i'll shop at Lowes now.
Go figured they'd detect Cocaine at UCSB. I went there in the 80's, and I detected plenty of coke. Also the same school where a Psych grad got busted for stealing cocaine from lab rats.

until someone realises that Ritalin sets off the sensor, due the the similarities of their structure.
"Aptamer" is too general a term, and it is not limited to DNA. Please call it an oligonucleotide.
You sprinke a suspect with substance X, which your sensor can detect in minute quantities. You can then follow the trail of X using your handy-dandy biosensor, finding everywhere they went, everyone they met, all the money they handled, and their current location.

With this new sensor I will know when its time to go back to the bathroom and reapply before the shit wears off.
anyone residing around the area will know what I'm talking about.
I'm sure they had all the coke they needed for testing.
2 years and no mod points. Join reddit. Because openness is good.
Who modded my post up? It was intended as a personal reply to correct some of the Parent poster's misconceptions. It has nothing to do with the Article and is completely off-topic! Mod me down!
Cocaine has a plasma half-life of 90 minutes. Current cocaine drug tests detect metabolites, not the drug itself, and even those only work within 24-48 hours after using.
Check it out. These are Euros. They haven't even been in circulation very long.
I know it was a joke, but the dogs can usually detect more than one drug. :-)
I'm sorry, the number you have dialed is an imaginary number. Please rotate your phone 90 degrees and dial again.
I'm a current UCSB student and I read about this in the school newspaper a couple weeks ago. The biosensor can actually be set to be used for other things than cocaine, but the article stated that cocaine was just a material that they used to test it on. *cough cough* A convient material. *cough cough* So it has many other uses than just cocaine testing. But in other things..... GO GAUCHOS! TAKE THAT UCBerkeley! You don't see UCB on Slashdot now do you!
That government installed biosensor on your sewer outlet won't need a warrent.

According to this article on the Science Blog two local high school students helped on the research: http://www.scienceblog.com/cms/might_gauchos_devel op_portable_cocaine_sensor_10107.html
...
The high school students made their own sensors and collected data shown in a graph in the scientific article they co-authored describing the work.
Elaine Doctor, a senior at Channel Island High School in Oxnard, Calif., and McCall Wood, a senior at Santa Barbara High School in Santa Barbara, Calif., participated in the summertime Research Mentorship Program at UCSB on this work. Elaine Doctor said, "At first I felt kind of intimidated by all the graduate students who are used to all the equipment, but we caught on really fast and everyone was really helpful. I felt honored to help America's war on drugs." Elaine plans to continue her studies in the sciences, either in biochemistry or biology.
McCall Wood said, "I'm really excited about this work. It let me know what research is like and I definitely want to pursue this. Everyday we would go into the lab and test a different hypothesis. I found it really exciting and extremely challenging. I found my limits, like patience. Being in the lab every day taught me so much about myself and about science in general. It's not really the results that were so important but the journey and the process."

And there's a pretty good chance you're eventually going to have to take a drug test. According to a 2004 American Management Association (AMA) study, 61.8 percent of companies surveyed said they test employees for illegal substances.

This from a high school senior? What is wrong with teenagers today? I'm appalled by this clear decline in standards. A high school senior is... happy... to be helping... the Man... crack down on drugs? FOR FUCK'S SAKE! Someone get this kid to a fucking party already!
I weep for the future if this is typical of kids today. It's horrifying.

But frankly we got stuff to pass every kind of drug test there is and every home drug test out there:

I've often wondered if Coke still laces Coca Cola with Cocaine to "relieve pain." I guess maybe now we can find out.
So when your spaztic buddy spills the coke all over the table it's now a little bit easier to filter out the yay from the common dirt.

Sechedule I substances (such as pot and lsd) have (paraphrase) "extreme danger of addiction with no medical or scientific uses", and as such licenses may *not* be obtained for these substances (please correct me if i'm wrong, but i'm pretty sure i'm not)
obviously, some states are trying to use local legislation to get around this classification where the medical uses of pot are concerned, but the federal govermant claims that federal law trumps
