Syväjäähdytys
Syväjäähdytys, also known as cryopreservation or vitrification, is a process where biological material is preserved at very low temperatures, typically in liquid nitrogen at -196 degrees Celsius. The primary goal of syväjäähdytys is to prevent cellular damage that can occur during the freezing and thawing processes. This is achieved by using cryoprotective agents (CPAs) that lower the freezing point of water and prevent the formation of ice crystals, which can rupture cell membranes.
The technique is widely used in various fields. In medicine, syväjäähdytys is crucial for preserving reproductive
Successful syväjäähdytys requires careful control of cooling and warming rates, as well as the concentration and
