Funny, my initial assumption before reading the article was that it was going to be something nano-scale.<p>Also, the article is focussing solely on the "this stuff dissolves in water and is bio-compatible" part of the equation, pretty much ignoring the "fight infection" part.<p>So I'm guessing that this is just a proof-of-concept of the "electronics that dissolve in the human body without killing you" part of a complete solution (which is very cool, don't get me wrong...). If so, is the fighting infection part a solved or trivial problem? I'm trying to figure out how a chip inserted into a single point in a body fights infection.
