Heart of Gold: Nanotechnology (9.28.11)
Well the old saying that someone has a "heart of gold" is no longer just a saying. Scientists have found that placing gold nano-wiring within new heart tissue (cardiomyocytes) implanted on the damaged portion of the heart after a myocardial infarction (heart attack) allows for greater electrical conductivity with the underlying heart than just patching the heart with cardiomyocytes alone. Nanowired three-dimensional cardiac patches
