Ferrofluid actually is the stuff of science fiction. It was created at NASA as a strategy to transfer gasoline in area, and sometime quickly, it might be used to pilot medication by way of your physique.
This weird good is fabricated from three elements: magnetic nanoparticles, like iron oxide; a particular coating that retains the particles from clumping collectively; and a water-based or oil-based liquid. What makes ferrofluid “magical” is that you should utilize a easy magnet to maneuver it round from a distance, with out utilizing pumps or wires.
The primary ferrofluid was invented by a NASA engineer named Steve Papell within the early 1960s. His thought was that if you happen to add these magnetic nanoparticles to gasoline, you’ll be able to transfer it round in zero gravity with a magnetic subject. That didn’t actually pan out. However since then, ferrofluids have been used far and vast. Immediately, you could find ferrofluids in audio system, onerous drives, and skateboards. However the way forward for biomedicine is the place issues get actually thrilling.
Scientists like Thomas Webster, the director of the Nanomedicine Laboratory at Northeastern College, are wanting on the methods ferrofluid can kill most cancers cells, combat drug-resistant infections, and even assist neurons talk with one another. Watch the video above to delve into the sci-fi world of ferrofluid — and luxuriate in some hypnotizing goo alongside the way in which.
If you wish to experiment with ferrofluid, watch the video under, the place Verge video director Cory Zapatka and supervising director Tom Connors talk about the method of working with ferrofluid and present some photographs that didn’t fairly make the minimize.
