Tiny Robots for Drugs

Taking medication isn't really too taxing of a task, right? You just pop one in your mouth and wash it down with some water, and you're done. Although, they don't always take effect right away so you would still have to deal with your headache or allergies for some more time before getting relief.

But, what if the drugs we take have the capability to get to the problem right away and alleviate our condition in one or two minutes tops? That would be awesome. Actually, some scientists are doing research to do that through microrobots.

One day we may be able to ingest tiny robots that deliver drugs directly to diseased tissue, thanks to research being carried out at EPFL and ETH Zurich.
The group of scientists – led by Selman Sakar at EPFL and Bradley Nelson at ETH Zurich – drew inspiration from bacteria to design smart, biocompatible microrobots that are highly flexible.
Because these devices are able to swim through fluids and modify their shape when needed, they can pass through narrow blood vessels and intricate systems without compromising on speed or maneuverability.
