👉 Cryogenics is a field of physics that deals with the use of cryogenic materials, such as liquid nitrogen or argon, to stabilize and preserve biological tissues or other living cells. It involves the operation of these materials at extremely low temperatures, below freezing point (0°C), in order to prevent cell death and maintain normal functions within living organisms. Cryogenics has applications in medical imaging, cryopreservation of human organs, and the preservation of genetic information.
