Abstract

Hemoglobin-vesicles (HbVs) are developed as artificial red cells. The HbV suspension does not have a detectable colloid osmotic pressure. Therefore, the intravenous infusion of large amount of HbV requires an addition of a plasma expander (e.g., albumin, polysaccharides, or gelatin solution). Here, we analyzed the viscoelastic property of these suspensions. In the case of HbVs suspended in albumin, the viscoelastic property showed approximately Newtonian. Other suspensions showed shear thinning due to reversible aggregation of HbVs induced by the interaction with the plasma expanders.
