Hard even to imagine such a thing! However, perhaps one could preserve, not
an entire cell nor even a section, but a sort of "ghost" of one, contents
immobilized on a substrate like NC or in a gel.
Or, if it's only a particular enzyme whose activity you care about, find
some affinity substrate for it you can freeze-etch cells into/onto. What
enzyme or enzymes are you interested in?
