Episode 6: Hemodialysis and the Birth of Artificial Organs

What role do materials play in artificial organs? Are there materials that body simply won't accept? In this episode we talk about the birth of artificial organs as we describe the history of hemodialysis which is critical for treating chronic kidney disease. We introduce materials science fundamentals associated with mass transport across semi-permeable membranes such as Ficks First Law. We then tell the story of Willem Kolff and others who pioneered the invention of hemodialysis and describe the role that materials played in that process then as well as now.
