Description
Biological and medical applications
(1) Eliminate red fire ants.
(2) Rapid freezing can be used to help stop bleeding and remove bleeding during surgery
Insert a -170 degree needle into the cancerous tissue and freeze the cancer to death
To remove the superficial layer of the skin that needs to be removed.
(3) preservation of living tissue, biological samples, and storage of sperm and eggs;
(4) Used to quickly freeze biological tissue and prevent tissue from being destroyed.
cryotherapy
Liquid nitrogen cryotherapy is a new technique in the field of modern therapeutics. Liquid nitrogen cryotherapy is a comprehensive effect of cryobiology. Normal cells in a state of extreme freezing can undergo irreversible damage. It is through the extreme freezing of the state, the rapid death of the cells in the disease, so that the disease can be normal recovery. Use to treat wart, corns and skin disease commonly.
Cryosurgery is also used to treat breast cancer. IceCurean, an Israeli medical company, developed a new technique for using cryotherapy to treat breast cancer in 2012, freezing and killing breast cancer cells with liquid nitrogen, and is testing it in clinical trials. If the trial is successful, breast cancer patients could one day be able to have their tumours removed without surgery.
Industrial USES
In industrial production, liquid nitrogen obtained by compressed liquid air fractionation can be used as a deep refrigerant. Because it is chemically inert, it can be directly in contact with biological tissues and immediately frozen without destroying biological activity, so it can be used
(1) Freezing and transporting food quickly, or making ice products;
(2) to conduct research on cryogenic physics;
(3) Demonstrate low temperature state in science education. At room temperature soft objects soaked in liquid nitrogen, will be as brittle as glass;
(4) Provide a high temperature superconductor to display the temperature required for superconductivity.
(5) can be used as refrigerant to quickly freeze biological tissue to prevent tissue damage.
(6) for industrial nitrogen fertilizer.
(7) for chemical testing.
