[SIZE="3"][COLOR="Yellow"]Germ-inspired microbots shape shift to deliver drugs, unclog arteries - David Szondy July 24, 2016[/COLOR]
Microbots have made great strides in recent years, with developments ranging from tiny experimental robots that can swim through the bloodstream to origami-likecreations designed to be swallowed. But one of the tricky problems is figuring out how these microbots are supposed to propel themselves through a miniature world where standard propellers aren't very efficient.
Selman Sakar at EPFL and Hen-Wei Huang and Bradley Nelson at ETHZ are developing and testing a number of configurations of microbots that can not only move about, but can be produced quickly and in quantity using a new manufacturing technique. The result is a robot that can be controlled using an electromagnetic field and, when heated, can alter its shape.
The microbots are soft, flexible, and motorless thanks to the use of biocompatible hydrogel and magnetic nanoparticles. The latter act as mechanical reinforcers and react to electromagnetic fields, making the microbot move.[/SIZE]

5 more paragraphs followed, interesting reading.
The future possibilities might include an 'upgrade' from simple fluoridated water, to microbots in everyone's drinking water, & who knows what they might do, once inside us! :d evil: Perhaps they could be directed to perform activities in everyone, or, just someone in particular. hmy:
