Scientists have built a bionic cardiac patch that could act similarly to a pacemaker and monitor as well as respond to cardiac problems. The researchers from Harvard University constructed nanoscale electronic scaffolds that can be seeded with cardiac cells to produce a bionic cardiac patch -- the engineered heart tissue with ability to replace heart muscle damaged during a heart attack. I think one of the biggest impacts would ultimately be in the area that involves replaced of damaged cardiac tissue with pre-formed tissue patches said Charles Lieber who along with colleagues described the work in the journal Nature Nanotechnology.
