Researchers at Brigham and Women's Hospital have created cardiac patches that use nanotechnology to enhance the conductivity of materials to induce cardiac tissue formation.
Creation of these ultra-thin cardiac patches put medicine a step closer to durable, high-functioning artificial tissues that could be used to repair damaged hearts and other organs.
The cardiac tissue patches utilize a hydrogel scaffolding reinforced by nanomaterials called carbon nanotubes. To create the patches, the researchers seeded neonatal rat heart muscle tissue onto carbon nanotube-infused hydrogels. These novel patches showed excellent mechanical integrity and advanced electrophysiological functions. Moreover, they demonstrated a protective effect against chemicals toxic to heart tissue.
