Nanotechnology is on a much coarser scale than molecular engineering, and it is not just about nano silver, but more general nano scale effects of nano particles.
But they are often interrelated. Thin films created by molecular engineering that have nano effects, or can be made into nanowires, and then broken into nanoparticles.
And like carbon nanotubes, other material can be grown in situ. The last image is vanadium oxide nanoparticles that are grown for use in batteries. They look like sea urchins but they are metal oxide and only a few nanometers in diameter, giving them tremendous surface area. Those familiar with cell biology will note a similarity in surface area to the endoplasmic reticulum where biological nanomachines called ribosomes do their work.
And if you didn't learn about the endoplasmic reticulum in 8th grade, like kids in British commonwealth countries, ask yourself, is there a reason why this is the case? Were you being prepared to be RULED OVER by others?
Don't be angry at the minions of Britain or the Deep State. Just fix the problem and educate yourself NOW! Far more productive then endless moaning and discussion about who is bad and who is good. Be a BUILDER!
