kriopreservation

Kriopreservation, also known as cryopreservation, is a process used to preserve biological materials at very low temperatures, typically below -135 degrees Celsius. This technique is widely used in the fields of medicine, agriculture, and research to maintain the viability of cells, tissues, and even entire organisms for extended periods. The process involves rapidly cooling the material to extremely low temperatures, often using liquid nitrogen or other cryogens, to prevent the formation of ice crystals that can damage cellular structures. Once frozen, the material can be stored for long periods without significant degradation. When needed, the material is thawed gradually to minimize damage and restore its functionality. Kriopreservation is particularly valuable in the preservation of sperm, eggs, embryos, and organs for transplantation, as well as in the conservation of plant materials and biological samples for scientific research. The technique has revolutionized the fields of reproductive medicine, agriculture, and biological research by enabling the long-term storage and retrieval of vital biological materials.
