Artifical Blood

artifical Blood

how and why this blood is made. "Two main problems arise when hemoglobin is removed from the red blood cells; these problems account for the large amount of scientific research that has been conducted so far in this area. This means that significantly more PFC must be used. While it is still used today as a blood-volume expander, Ringer's solution does not replace the action of red blood cells so it is not a true blood substitute. Since pH control is vital for optimal growth, ammonia water is added to the tank as necessary. Hemoglobin-based products can use either isolated hemoglobin or synthetically produced hemoglobin. It is filled with warm water, food, and an ammonia source which are all required for the production of hemoglobin. Story Source: Materials provided by, university Of Sheffield. A method for the production of a synthetic hemoglobin-based product is outlined below.

Whi le true blood serves many different functions, artificial blood is designed for the sole. Even though they do not qualify as perfect red blood cell substitu tes. Presently, the prospect of using artificial blood is difficult to envision. Scientists believe that one of the future evolutionary innovations could be artificial blood substitutes that might pave the way to a new era.

In order to work, however, they must be combined with other materials that enable them to mix in with the bloodstream. A more recent approach is to use nanotechnology to encapsulate hemoglobin and enzymes inside biodegradable polylactic acid membrane nanocapsules some.15 microns in diameter. It received renewed interest when the shortcomings of the blood bank system were discovered during the Vietnam conflict. In experiments done on frogs, scientists found that they could keep frogs alive for some time if they removed all their blood and replaced it with a saline solution. Also, various physical and chemical properties of the finished product are checked such as pH, melting point, moisture content, etc. Another potential substitute was salt or saline solutions. This is in contrast to natural blood which can only be stored for one month before it breaks down. Other growth factors such as vitamins, amino acids, and minor nutrients are also added.
