Episode 6: Hemodialysis and the Birth of Artificial Organs

In Nazi occupied Netherlands an incredible breakthrough occurred

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.

To learn even more about the stuff we talked about, check out some of the references we pulled from when making this episode: Overview on membranes https://www.intechopen.com/books/updates-in-hemodialysis/dialysis-membranes-physicochemical-structures-and-features and Bowry, S.
