Scientists create 'plastic' blood

Scientists have developed an artificial plastic blood which could act as a substitute in emergencies.

Researchers at Sheffield University said their creation could be a huge advantage in war zones.

They say that the artificial blood is light to carry, does not need to be kept cool and can be kept for longer.

The new blood is made up of plastic molecules that have an iron atom at their core, like haemoglobin, that can carry oxygen through the body.

The scientists said the artificial blood could be cheap to produce and they were looking for extra funding to develop a final prototype that would be suitable for biological testing.
