Plastic blood: A new discovery in the field of medicine revealed
Nov 11, 2013

The University of Sheffield scientists have developed an artificial `plastic blood´, which could act as a substitute for real blood in emergency situations mainly in military operation during the critical situations.

As made from a plastic, it is light to carry and easy to store. Doctors could store the substitute as a thick paste in a blood bag and then dissolve it in water just before giving it to patients – meaning it´s easier to transport than liquid blood.

Donated blood has a relatively short shelf-life of 35 days, after which it must be thrown away. It also needs refrigeration, whereas the `plastic blood´ will be storable for many more days and is stable at room temperature. This product can be stored a lot more easily than blood, meaning large quantities could be carried easily by ambulances and the armed forces.

The artificial blood is made of plastic molecules that hold an iron atom at their core, just like haemoglobin, that can bind oxygen and could transport it around the body. The small plastic molecules join together in a tree-like branching structure, with a size and shape very similar to that of natural haemoglobin molecules. This creates the right environment for the iron to bind oxygen in the lungs and release it in the body.

While still in its development, the scientists hope this will make it particularly useful for critical applications.
