title: New hemoglobin substitutes.
abstract: Blood transfusion is an essential and ubiquitous component of medical therapy. Despite careful screening and processing, allogeneic blood still carries a small but definable risk of the transmission of severe viral disease and the induction of immunological reactions. The logistics of its storage and transport continue to present a challenge, and its dependence on human donors will always keep it a scarce resource. It is not surprising that in the latter half of the 20th century efforts to develop blood substitutes have gained increasing momentum.
