freeze-fracturing
freeze-frac·tur·ing (frēzґfrak″chər-ing) a method of preparing cells for electron-microscopical examination: a tissue specimen is frozen at −150°C, inserted into a vacuum chamber, and fractured by a microtome; a platinum carbon replica of the exposed surfaces is made, freed of the underlying specimen, and then examined.
