Scientists create temporary tattoo that detects if your drink has been spiked

Scientists have created a tattoo which can detect if a The drink was enriched With only a few drops.

The sticker, which is applied to the skin, can detect the presence of the drug Y-hydroxybutyrate (GHB) even in low concentration in a second.

Commonly used to increase drinks, depressed drugs from the central nervous system, known as the roof or GHB, was appreciated with sexual assault.

It causes drowsiness, slows down your breathing and reduces heart rate.

These drugs are colorless, insipids and induce stupor in victims who are similar to severe alcohol intoxication – leaving people vulnerable to sexual assault.

The prevalence of doping is high, 11% of British adults say they are generated at any time in their lives, according to Drinkaware.

He added that 9% of men and 13% of women reported that their drink was enriched.

There are means of people who can protect themselves drink dopingWith bands and specialized cards that change color when exposed to these drugs.

But many of these screening test kits are visible or take a few minutes to report a result.

In the study published in the journal ACS Sensors, researchers South Korea Enter to develop a quick action test for GHB which is carried on the skin using a tattoo type sticker.

Gyeong-ji Kim, I am Eun An, Kyong-Cheol Ko, Oh Seok Kwon and his colleagues created the stickers by placing a mold on the top of a thin plastic film decorated with tattoo drawings.

They poured a mixture of gel into the mold which contained a chemical receiver which becomes red when it detects the GHB.

The back of the sticker was then covered with a diluted glue solution, so that it can stick to the skin.

The researchers tested the capacity of the sticker to detect small amounts of GHB in a variety of drinks: whiskey, vodka, beer, Soju (a Korean alcoholic drink) and coffee.

The medication was detected in a second after being in contact with contaminated drinks. He even changed color when he detected drug levels lower than that would induce serious physiological symptoms – 0.01 micrograms of GHB in 1 milliliter of drink.

The sticker is designed to be able to discreetly soak a finger in a drink, touch the drop in the sticker and see the result almost immediately.

A positive result is displayed up to 30 days after detection, which could be important if necessary as a form of proof of falsification.

Researchers say that their sticker technology is inexpensive and easy to make, and that it could soon be available commercially.
