You can't. SEM requires coating the scanned things in a thin layer of metal.

- lokki 12y agonit-pick alert Basic SEM work requires a conductive surface (carbon coatings also work), and in some cases you can skip that if you have a good carrier gas. The real limitation here is that most SEMs require you to pump down to vacuum, which would eliminate the water. Even variable-pressure SEMs that operate close to atmosphere require a purge, first. So the limit is the vacuum, not the metal coating.
