Artificial Cells as Bioreactive BiomaterialsArtificial Cells and Organs Research Centre Faculty of Medicine McGill University 3655 Drummond Street Montreal, Quebec, PQ Canada H3G 1Y6 Artificial cells can have the same dimensions as biological cells. They can enclose and retain a large variety of bioreactants. Artificial cell membranes can have the required permeability characteristics to allow the rapid equilibration of external molecules to be acted on by the enclosed bioreactants. Polymer, protein, protein-lipid, polymer-lipid, lipid or other materials can form artificial cell membranes. It is possible to vary the membrane thickness and permeability characteristics over a wide range. Many different forms of bioreactive artificial cells are available. This article contains only a few examples. This includes its applications in (1) red blood cell substitutes; (2) immobilisation of enzymes, multienzymes with cofactor recycling, cell cultures and other biotechnological applications; (3) hemoperfusion in kidney failure, poisoning, removal of aluminium and iron; (4) use in liver failure; (5) other applications in microencapsulation.
Key Words: Artificial cells microencapsulation blood substitutes hemoperfusion immobilised enzymes immobilised cells artificial kidney artificial liver detoxification blood purification immunosorbent.
