The artificial blood is created by extracting hemoglobin — a protein containing iron that facilitates the transportation of oxygen in red blood cells — from expired donor blood. It is then encased in a protective shell to create stable, virus-free artificial red blood cells. As these artificial cells have no blood type, there is no need for compatibility testing. The synthetic blood can reportedly be stored for up to two years at room temperature and five years under refrigeration.
Thinking quickly, Japan constructs a homemade blood from a scientist, a shell and a blood.
Joking aside, I remember articles on artificial blood from 20 years ago, but it always failed in trials. I’m glad to hear things have progressed a good bit.
