Giving cardiac patients a heart of gold nanowires could ensure engineered tissue works like it should, pulsing in unison to make the heart beat. First growing nanowires and then growing heart cells, engineers from MIT and Harvard University say their new muscle-machine blended heart patch improves on existing cardiac patches, which have trouble reaching a consistent level of conductivity.
In a successful test of a prototype nanotech vaccine patch, Australian researchers at the University of Queensland used a patch smaller than a postage stamp to deliver vaccine through the skin without needles, and with just 1/100th of the vaccine normally required to evoke a protective immune response, according to Pharmacy News.
