not the first time

To our knowledge, this is the first example demonstrating observation of living organisms using SEM in this field.

This is a nice paper but the premise that this is the first time that living specimens have been viewed with a SEM is incorrect, in 1977, David Scharf wrote a book called Magnifications in which he explained his technique for capturing images of living specimens including many excellent photos.

I checked PubMed and found these from 1967:

Electron microscopy of living insects.
R F Pease, T L Hayes, A S Camp, N M Amer
Electron micrographs of living specimens of the various developmental stages of the insect Tribolium confusum have been obtained with a scanning electron microscope. In most cases the specimens resumed their normal activity after being examined with the electron microscope and under went metamorphosis into the next stage.
Science. 1967 Jul 28;157 (787):443-5 6028030

Stereoscopic scanning electron microscopy of living Tribolium confusum
by Thomas L Hayes, R F W Pease, Ann S Camp
The scanning electron microscope has been used to produce stereoscopic pictures of living Tribolium confusum at magnifications up to 1300 times. The physiological implications of survival in the environment of electron beam scanning are discussed.

Insects, mites and tardigrades have survived EM, but have any of them been seen to move while under the beam?
