Making artificial blood for transfusions
(PHYSorg.com Chemistry)

Blood transfusions can save the lives of patients who have suffered major blood loss, but hospitals don`t always have enough or the right type on hand. In search of a solution, researchers have developed a promising substitute using blood`s oxygen-carrying component, hemoglobin. The in vitro study, reported in ACS` journal Biomacromolecules, found that the modified hemoglobin was an effective oxygen carrier and also scavenged for potentially damaging free radicals.
