Then you should know that science advances mostly in small steps instead of big ones? And that additional data helps supporting other ideas, so that other researcher can build on those?

From a quick search, wearable tattoos for drug testing are a pretty recent development. And often it’s not only about the what, but especially in an early field about the how. Other researcher can look into this and get ideas for how to incorporate the fundamentals for other drug testing compounds.

Is this contribution going to save the world or stop all date rape drugging? No.

Thanks for your input.

While it isn’t the sole mean to end all date rape drugging, it is one additional tool to combat it. And the question regarding price is valid, but easier and more hidden way of using it is also an important factor for some. Not everybody is comfortable making a big scene in a bar.

Regarding selectivity: as an expert, is there a better indicator with broader selectivity without too many common false positives? As chemist, I can’t really imagine that, since the chemical structures I find for other date rape drugs are so different and no common structural motive between them.

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.

I mean, you are free to go into the lab and research your own selectively recognising, non-toxic, stable, easy to use chemical. Shouldn’t take you long since you are such an expert.

Kinda, but the thing this time is that they will change it f unilaterally rom their side, even if you specifically disabled this connectivity on your phone. So they want that data reallyyyyy badly. So even more important to not give it to them.
