cryogenic preservation
Cryogenic preservation involves cooling biological material, such as cells, tissues, or whole organisms, to very low temperatures to halt all biological activity and prevent decay. This process aims to preserve the sample in a state where it can potentially be revived in the future. Typically, substances called cryoprotectants are used to prevent ice crystal formation, which can damage cells during freezing. Cryogenic preservation is used in medicine for storing sperm, eggs, or tissues, and in research for long-term storage of biological samples. While revival techniques are still under development, the goal is to maintain biological integrity over extended periods.
