Do you think that our blood can be replaced by plastic. It's sounds crazy but this is a facts. Blood made from plastic may one day be able to save lives in medical emergencies where real blood is not available. Lane Twyman PhD, from University of Sheffield has developed a molecule made from polymer(plastic) and porphyrin that hold iron atoms at their core. It is similar in size and shape to haemoglobin and mimics the red protein responsible for transporting oxygen in the bloodstream. The idea of pumping plastic into bloodstreaam sounds unsafe, but Twyman says porphyrin are natural and the polymer component is likely to be ignored by the body's immune system. Although confined to the lab at the moment , if proven successful in humans, plastic blood may be used on the battlefield where quick replacement of blood would save lives.
