That’s gonna be a nope from me fam.

They used to use ferrofluid as a contrast in medical imaging but all of it got pulled not because of the tale of darth plagus the wise who said don’t inject the black ooze, but because the people who feed and inject into you radioactive particles so they can get a better picture decided it was too unsafe.

Which tbh good but that happened in the 0s.

Imma pass on the Too Hot For Medical Science brita, thanks.

Mia Heller of Virginia said she got the idea after learning that government agencies were not funding filtration programs

That's awesome. "What, nobody's working on it? okay watch this-"

The final result? A filtration system about the size of an average home appliance that removes roughly 95.5% of microplastics — a level that is competitive with many current filtration methods.
Heller’s system uses a magnetic liquid called ferrofluid. As water passes through the system, the ferrofluid attaches to microplastic particles. A magnet then pulls the contaminants out of the water, leaving cleaner water behind.
The process also allows most of the ferrofluid to be collected and reused, which could help keep costs down over time.
“The result is an affordable, low-waste filtration system without the use of a solid membrane,” Heller said.

I wonder how the mechanical process actually works. Very interesting.

And of the ferrofluid that gets by? How does that effect water treatment and distribution? What level of ferrofluid is safe for humans? Does it pass through? Does it accumulate?

Questions that need to be studied and answered before it can go to market or large scale.

Hopefully this gets the attention of some universities and grants to get it.

Same concept from 7 years ago: https://www.youtube.com/watch?v=AJUOjBhJe1E
