New nanotechnology artificial blood can be stored for up to two years at room temperature.

Heating the artificial blood at 60C for 10 hours, followed by nano-filtration eliminates viruses and provides an exceptionally safe product.

The resulting product can be stored for two years at room temperature, while human red blood cells can be stored only three weeks at 4C.

Artificial oxygen carriers which are lipid vesicles encapsulating hemoglobin and bone marrow-directing drug delivery materials have been developed by this technology.
