Cryofixation
Overview
 
Cryofixation is a technique for fixation or stabilisation of biological materials as the first step in specimen preparation for electron microscopy. Typical specimens for cryofixation include small samples of plant or animal tissue, cell suspensions of microorganisms or cultured cells, suspensions of viruses or virus capsids and samples of purified macromolecules, especially proteins.

The method involves ultra-rapid cooling of small samples to liquid nitrogen temperature (-196 oC) or below, thus stopping all motion and metabolic activity, and preserving the internal structure by freezing all fluid phases solid.
Quotations

My friend, you have seen this incident based on sworn testimony. Can you prove that it didn't happen? Perhaps on your way home you will pass someone in the dark, and you will never know it, for they will be from outer space. Many scientists believe that another world is watching us this moment. We once laughed at the horseless carriage, the aeroplane, the telephone, the electric light, vitamins, radio, and even television! And now some of us laugh at outer space. God help us... in the future.

Lt. Harper: One thing's sure: Inspector Clay is dead — murdered — and somebody's responsible!
