Cryonics is an experimental Human preservation procedure whereby patients who no longer can be kept alive with today's medical abilities are preserved at low temperature for treatment in the future.

Cryonics - preservation and storage at ultra-low (cryogenic) temperatures - offers the unprecedented possibility of allowing the older generations of people alive today, and those with terminal illnesses, to take advantage of the (nano)technology of tomorrow in order to prolong life. Cryonics, also called cryonic suspension, ultrahibernation, or cryostasis, is the technique used to store human bodies at extremely low temperatures with the hope of one day reviving them and restoring them to health. Mature molecular nanotechnology is expected to infer the ability to heal cells at a molecular level and is a vital component of this theoretic life support technology. Cryonics should not be confused with cryogenics, which is defined as, "The branches of physics and engineering that involve the study of very low temperatures, how to produce them, and how materials behave at those temperatures."
