Now a group of scientists in the UK have claimed to have discovered the right way to manufacture synthetic blood and have even succeeded in doing so. The National Health Services of UK has announced its decision to start experimenting on synthetic blood in 2017 on a group pf 20 people. The blood substitutes are not meant to replace blood, the scientists said. Instead, synthetic blood is only meant to carry out the functions of actual blood wherever it fails. As such, synthetic blood transports oxygen.
