> the researchers designed ZIF-8 rods with diameters about 1/15 that of a human hair
Always amazes me how we're able to create things this small/thin.
> In simulated radioactive wastewater, the microrobots removed 96% of the uranium in an hour
That's a very respectable number, I'm curious how they simulated waste water and what the differences would be with real waste water.
> The team collected the uranium-loaded rods with a magnet and stripped off the uranium, allowing the tiny robots to be recycled.
And they're reusable? Bravo!

What about non-Uranium isotopes?

So it appears as if these MOFs capture the uranium and then can be collected.
From the title I expected the micro robots to actually get rid of the material. We still need a way to process the collected uranium and find a way to extract the MOFs from groundwater in case of leakage.

Their "motor" is just a bit of platinum, which makes bubbles in hydrogen peroxide: https://www.youtube.com/watch?v=A6nGjRB1_s4
I wonder how much H₂O₂ is required per liter of H₂O?

So what do they then do with the uranium?
Storage is still a problem, right?
