Researchers in the UK are developing artificial blood that could potentially replace real blood in emergency situations, promising a tremendous impact for military and emergency medical service applications.
The blood is made up of plastic molecules that hold an iron atom at their core. Like hemoglobin, the artificial blood binds oxygen and transports it throughout the body.
This 'plastic blood' can be stored as a thick paste and dissolved in water when needed. Because of this, it's much easier to transport and store than the real thing.
Donated blood only lasts for about a month. After that, it must be discarded.
'Plastic blood' on the other hand, can last significantly longer and - unlike real blood - remains stable at room temperature.
