Cryopreservation

Cryopreservation is the process of preserving biological materials, such as cells, tissues, or organs, by cooling them to extremely low temperatures—typically using liquid nitrogen—to suspend all metabolic activity and prevent decay. This technique has revolutionized fields like medicine and research by enabling long-term storage for applications such as fertility treatments and organ transplants, though it requires careful management of cryoprotectants to avoid cellular damage from ice formation.
