Heart repair difficulties Heart nanotechnology
1 heart repair difficulties 1.1 heart patches 1.2 tissue scaffolds 1.3 nanoparticles 1.3.1 composition 1.3.2 research 1.4 polyketal nanoparticles 1.4.1 composition 1.4.2 use in myocardial infarction heart repair difficulties being able fix cardiac tissue has been damaged heart attack or heart disease not simple , 1 of major challenges today in field of tissue engineering ( popular science ). because heart cells not easiest objects create in lab. takes enormous amount of special care , work develop cells beat in sync 1 ( popular science ). after heart cells have been made, large task insert cells inoperable parts of heart , them working in unison tissues still working ( popular science ). heart patches there have been several successful examples of use of stem-cell- based heart patch developed duke university researchers, ( popular science ). biomaterials make patch made of either biological polymers alginate or synthetic polymers such polylactic acid ( nature nanotechnology ). these ...
