A temporary “tattoo” can provide a partygor in search of a safe night, which is a secret indicator for detecting drugs often used to spike drinks in public bars and clubs.
Rohypnol – called “roof” – and GHB, sometimes called “liquid ecstasy” or “fantasy”, club drugs are used, often by young people, by young people, bar and nightclubs, in rush and other nightlife settings. It is illegal drugs at many places including the United States, Britain and Australia.
While some doses of thesis club drugs can cause a feeling of relaxation or enthusiasm, excessive dosage may have signs of drowsiness, diluted speech, loss of motor function, confusion and memory loss. Overdose and poisoning is so possible.
Drug regulators have identified both drugs, which are in the form of toxins of choice for criminals, who faint or close their victims, and then sexually harass them.
Because thesis thesis is less love, clever and colorless drugs, it is especially difficult for those who want a safe night to find out if their drink has become sharp.
Although a new report published in his magazine in American Chemical Society ACS sensor, A innovation from a South Korean research group is that can make the identity of the drug practically comfortable.
Rapid, prudent test for danger drugs
There are products that allow people to identify whether a drink has been pointed. Thesis appears in the form of strips that can be immersed in a drink, indicating the presence of an untrue chemical with a color change.
However the search technique can take minutes and leave a person sensitive to other social threats with a clear test method.
The new rapid test developed by scientists can introduce an alternative to the South Korean government.
Like a tattoo, but real a removable sticker, the new product may provide an opportunity to recognize the presence of GHB quickly and subtle.
The silicone sticker is a solution embedded in the film with an iodide indicator called BHEI. When the GHB comes in contact with a solution containing GHB, the indicator turns from yellow to red.
According to the reported results, the sticker changed the color almost immediately when exposed to GHB drops in whiskey, vodka, beer or coffee.
For stickers wearing, they will only need to highlight their markers in a drop of their drink for change. It was sensitive to detect 0.01 mg GHB per milliliter.
“This innovation represents an active and accessible solution to prevent the sexual assault with drug-facilities, increase the safety of personnel and promote a sense of control and awareness in a high-risk environment,” authors have written in the study.
Promising, but further testing is required
This is not the first time that the censor has developed bees to detect date rape drugs. More than a decade ago, a group of the National University of Singapore developed a fluorescent sensor platform, which can be made in drinks styers and straws to indicate drinking drinks with GHB.
A US startup first invented a quick testing platform which was tested for several drugs using the test disc.
But fast test products will need to be developed before going to the market.
Kabrena Roda, a forensic toxicologist at the Pacific Northwest Laboratory, US, said some spot tests may be unreliable.
“Inseparable, the methods of spot detection can often be highly false positive councils as search as search – that is, telling you that it is not really there when it is not there,” Rodda, who was not involved in the new study, told the DW in an email.
“It can motivate people to avoid drinks that can be safe, which in turn may be wrong that GHB is being shed in people’s drinks.”
However Roda stated what sticker tests developed by Korean researchers are “admirable and important”.
An enterprise company has now been sacrificed to bring and bring the product to the market in South Korea.
But adaptation and adaptability for other goal drugs, currently limited.
“A custom mold should be made and should be filled with GHB chemical receptor-containing agarose gel, limiting independently designing shapes such as actual tattoos,” said Gieng-G Kim, the lead writer of the study located at Suungkankwan University in South Korea. “Customization is somewhat possible, but it is technically constrained.”
“We have not yet developed chemical receptors to detect other drugs. However, if receptors search for substances is developed as opioid or synthetic canbinoids in the future, we believe that they can be integrated into our tattoo sticker platforms.”
