Making a microscopic swarm move through a maze

A microscopic swarm, just a few millimetres in length, can move through a maze with a just few clicks of a mouse. The swarm is formed from millions of magnetic nanoparticles suspended in a rapidly oscillating magnetic field. Researchers in China have been testing the new technology by altering the magnetic field to move the swarm around various obstacles.

Such an exciting work! Can't wait for its biomedical applications.

pfffft i already have that stuff swarming around my body from that time the aliens took me....
...and so do you! (scary music)

Looks like an early web flash game from Newgrounds

Interesting technology and I enjoyed the video

Hmm. shades of Magneto. This tech could easily be used as an assassin's weapon. Artificial blood clot to the heart, lungs or brain your trget dies and then you an disperse the clot's magnetic particles.

في رأيي ، أعتقد أن هذه التكنولوجيا هي حديثة نسبياً ، ولكن عندما تقرأ الورقة العلمية ، فأنت متأكد أنها حديثة ، لذا أعتقد أن هناك فشلاً في صنع الفيديو.
أعتقد أن المشروع متخصص في مجالات الكيمياء الحيوية ليس في العملية الجراحة كثيراً

This is so sad, alexa, play despacito

Just once I'd love to see the paper authors and university press department be HONEST about this kind of research and simply say "this has no real world applications at all and is completely useless, we just thought it was neat.". Then I would actually respect them. The constant absurdly implausible reaching for "applications" to keep the funding $ flowing is so lame.

Everything shown on this channel has "medical applications", but they never say what. I think its a very poor explanation for why something is useful. Scratch youre head a little more and suggest some real applications. If you can come up with one its probably not very useful
