TAU researcher harnesses gold nanoparticles to engineer novel biocompatible cardiac patch
Because heart cells cannot multiply and cardiac muscles contain few stem cells, heart tissue is unable to repair itself after a heart attack. Now Tel Aviv University researchers are literally setting a new gold standard in cardiac tissue engineering.
Dr. Tal Dvir and his graduate student Michal Shevachof TAU’s Department of Biotechnology, Department of Materials Science and Engineering, and Center for Nanoscience and Nanotechnology, have been developing sophisticated micro- and nanotechnological tools — ranging in size from one millionth to one billionth of a meter — to develop functional substitutes for damaged heart tissues. Searching for innovative methods to restore heart function, especially cardiac “patches” that could be transplanted into the body to replace damaged heart tissue, Dr. Dvir literally struck gold. He and his team discovered that gold particles are able to increase the conductivity of biomaterials.
In a study published by Nano Letters, Dr. Dvir’s team presented their model for a superior hybrid cardiac patch, which incorporates biomaterial harvested from patients and gold nanoparticles. “Our goal was twofold,” said Dr. Dvir. “To engineer tissue that would not trigger an immune response in the patient, and to fabricate a functional patch not beset by signalling or conductivity problems.”
