Episode 467 - Repairing throats and better implants

January 24, 2022

How can we make stronger implants that don't get rejected by the body? Bioactive materials can help make implants feel more at home. Replacing a knee or a hip requires not just strength but also compatibility. A new coating method makes it easier for implants to fit in. An implant has to be strong yet flexible, friendly to cells but not bacteria - it's challenging. Your vocal chords are subject to extreme forces, so how can we design an implant to repair them? Hydro-gels can help repair damaged organs and tissue even in extreme environments like your vocal chods.
