Transparent Transistors Printed On Paper

I've read the fine article, and it might not be immediately clear from the summary that the breakthrough here is not the transistor per se - the important step was in using the "nanopaper" (which is tech that is in fact NOT 2KA old).

And while the nanopaper may be biodegradable, I am wondering about the carbon nanotubes they are printing on top (as conductors). While the toxicity of carbon nanotubes is still being studied, there are good indications that they might behave similar to asbestos fibres. So not something you would necessarily want to throw on your compost heap.
