Answer:
Preservation of cornea is done in liquid nitrogen. (N2)
Explanation:
- Liquid Nitrogen has a temperature of -196 degree Celsius.
- Cryopreservation :
- To the cornea is added an anti-freezing agent like glycerol or ethanol.
- The anti-freezing agent prevents the formation of ice-crystals inside the cells of the cornea.
- This way the cells of the cornea are protected from getting ruptured or torn as a result of freezing and thawing.
- The cornea in the anti-freezing agent is kept in liquid nitrogen. The low temperature of liquid nitrogen prevents degeneration of the cornea tissue.
- This way the cornea is kept viable until transplantation is done.
