Electron microscopes are fraudulent. Not withstanding the bullshit that is called "isolation," the preparation methods before you can even do EM is proof enough that what is being "looked at" isnt natural and is NOT proof of anything.
And fuck you if you think im going to limit an answer to yes or no about something more complex than just a yes or no answer.
go to viroliegy.com and read about EM there. Watch some videos that are even on Jewtube of Harold Hillman and how the preparation methods for histography, EM and various other tools damage the samples to the point that they are unrecognizable from what you initially intended to look at.
