Published Wednesday by the American Chemical Society (ACS), the study from Korean researchers developed a multicoloured temporary tattoo that reacts to the presence of GHB, a compound described as “commonly associated with drug-facilitated sexual assault.”
According to the study, the chemicals in the tattoo can detect concentrations of GHB in beer, liquor or coffee, changing colour from yellow to red in order to alert the wearer that their beverage may have been spiked.
“In practice, a wearer could dip a finger into a beverage, touch the drop to the sticker and see the result almost immediately,” the release reads.
The newly developed tattoos not only allow the users to test their drinks discreetly, but also act far faster than some older tests, delivering results in less than a second, rather than minutes.
Researchers also say the results last for up to a month, which can help preserve evidence of suspected tampering.

TIL that only experts in a field can offer criticism of that topic!
You completely missed the point.
You complained in a pretty smug way about science not being fast enough.
Problems often don’t have easy solutions or they would have been already found. Finding solutions which fulfill all or at least most requirements takes time. If you don’t like that, start contributing. But just sitting there and complaining that it doesn’t work like a video game where X research happens after Y time is just stupid.
Criticism is fine. But you just wanted to feel smug as e evident by the way of your comment.
Thanks for telling me what I said. I keep learning new things
I literally review research in my day job. I’ve never had someone present a study and say “we want to investigate this idea that’s waning in popularity instead of being on the frontier of science”
