SoylentNews is people

Arthur T Knackerbracket has found the following story:

Many of the problems human engineers face have already been solved by nature, so why not use those as a jumping off point? Making artificial versions of the humble leaf has been an ongoing area of research for decades and in a new breakthrough, researchers from the Eindhoven University of Technology (TUE) have fine-tuned their artificial leaf design and used it to produce drugs for the first time.

[...] The new artificial leaf design from TUE builds on the team’s previous prototype, presented in 2016. Back then, the device was made of silicon rubber, but in the new version that’s been replaced with Plexiglas for several reasons.

“This material is cheaper and easy to make in larger quantities,” says Timothy Noël, lead researcher on the team. “It also has a higher refractive index, so that the light stays better confined. But the most important thing is that we can add more types of light-sensitive molecules in (Plexiglas). As a result, in principle all chemical reactions are now possible in this reactor across the entire width of the visible light spectrum.”

The leaf has started to earn its keep, too. The team put it to the test and found that it was able to successfully produce two different drugs: artimensinin, which is effective against malaria, and ascaridole, which is used against certain parasitic worms.

[...] The research was published in the journal Angewandte Chemie. An explainer of the artificial leaf can be seen in the video below.

    Get it to make some LSD, then I'll care.

      Wouldn't it be better to have an artificial leaf that could produce marijuana instead?

          The caffeine must flow.

          It is by the juice of caffeine the thoughts acquire speed, the hands acquire shaking, the shaking becomes a warning.
          It is by will alone I set my mind in motion.

        Not for me, personally.
        I derive too much satisfaction and amusement from growing my own legally.

          I recently harvested an Obama Kush(yes, really) autoflower, and the smell in my workroom is delightful...hippie air freshener FTW! 384 grams of tasty, potent, oh so frosty buds, not to mention about half pound of frosty trimmings to use for concentrates.

    Vitamin C, Vitamin D, etc. But if the leaves are producing them, what's to prevent anyone from just smuggling out some cuttings and growing their own, and chewing on the leaves?

      I would go for an artificial chewable leaf that could produce a pain reliever, like aspirin.

      Or a chewable leaf that was edible as food.

      (almost anything is edible -- at least once)

    This artificial leaf doesn't reproduce. Sunlight shines through micro fluidic channels catalyzing a chemical reaction. Does this reaction consume chemicals to produce its product? Is "leaf" even a good description? Leaf implies a lot of things that this does not seem to be.

      Well, it IS leaf shaped... as if that has anything to do with what it does or how it works.

      In other words, the fact that they made it leaf-shaped and showed pretty pictures suggests strongly to me that it’s junk science.

      I came here to say something similar. I'm guessing the 'leaf' is taking in some pretty complicated drug precursors and photo-catalyzing them. Unless the 'leaf' is creating drugs by taking in only CO2, water, and light (ok, plus micronutrients), then it's just a simple, inefficient bioreactor.

    plants make drugs!? why am I learning about this just now!?

    I think in all seriousness it would be an upgrade thought to just leave a plank of drug inducing cells in the backyard for the afternoon and then go out for a good lick session like it was an amazonian frog.

    I'm not sure, but according to my knowledge of humans and their wants and needs, there might be a way to make money on our planet with this idea.
