Abstract
A process for preparing artificial red cells comprising microdroplets of aqueous, stroma-free hemoglobin solution encapsulated in membranes of polymerized hemoglobin, said process comprising forming microdroplets of hemoglobin solution in a continuous oil phase, cross-linking the hemoglobin at the surface of the microdroplets with a suitable cross-linking agent to form the artificial red cells and recovering the cells. In one embodiment, a liquid membrane encapsulation technique employing a water-soluble cross-linking agent is used to form the cells. In another embodiment an oil-soluble cross-linking agent is present in the oil phase containing the hemoglobin microdroplets.
