Artificial protein can carry oxygen

There have been a number of attempts to create **artificial blood**, but most so far have some drawbacks, e.g. risk of heart attacks in the patients, usually trauma cases, that receive such transfusions. Researchers at the University of Pennsylvania have, however, now succeeded in constructing an artificial protein from scratch that is capable of carrying and delivering **oxygen** in the body and that is resistant to ingress by water which causes release of oxygen that can cause cellular damage.
