That is sweet, especially if it doesn't damage the blood cells.

There's still a big need for synthetic blood replacements, though. If they could get a really effective synthetic with no major side effects, you could help a lot of people with vascular issues.

Like sickle cell, for example. During a sickling episode, blood plasma can get past the blockages but not red cells. If you had a fluorocarbon synthetic with a particle size much smaller than a cell, it could get past the blocks and not only oxygenate the tissue, but also restore the sickled cells to normal faster.

Same with ischemic strokes and most heart attacks. You might be able to get a fluid synthetic where a red blood cell can't get, long enough to do a bypass or some intravascular surgery to open the vessel back up.

This is a great advance, but unfortunately they haven't yet solved the RH negative factor, so this blood is not for everyone. Still, it has a lot of promise and this development should be watched.
