To be clear, there are bacteria 5 microns long. A tenth of a micron is smaller than the human eye can see, by quite a bit. Certainly, some research labs have experimented with super fine printing, but from a practical standpoint, most people are going to have a hard time appreciating the difference and we aren't talking about bioprinting here.
Where are these research labs? I'm not saying you're wrong, but I'd like to see what they're up to.
