How Nanotechnology Can Help Treatment of Heart Failure | Taeghwan Hyeon | TEDxKFAS

Have you ever wonder what makes heart beat automatically every second throughout your life? The answer is electricity. Heart has special (a.k.a. Purkinje) fibers that have ability to self-generate electrical activity and produce electrical impulses. The self-generated electricity spreads over the heart to make heart contract and pump blood. However, injury in Purkinje fibers causes decrease in the pumping ability, irregular heartbeat, and low blood supply, which we call heart failure. Heart failure is a major concern in public health with a 5-year mortality rate higher than that of most cancers. Our research team used nanotechnology to develop a replacement for damaged fibers, conducting rubber mesh. Through Purkinje-like electrical stimulation, the electromechanical hugger could help recovery of heart function. Taeghwan Hyeon is a SNU Distinguished Professor at School of Chemical and Biological Engineering of Seoul National University, and also Director of Center for Nanoparticle Research of Institute for Basic Science. Over the last 20 years, he has studied the synthesis and biomedical applications of uniformly sized nanoparticles, for which he was listed on the Top 100 Chemists of the Decade by UNESCO&IUPAC (2011). Since 2010, he has served as an Associate Editor of Journal of the American Chemical Society. He is a Fellow of the Royal Society of Chemistry and the Materials Research Society. He received numerous awards including IUVSTA Prize for Technology (2016), Korea S&T Award (2016), Hoam Prize (2012), and POSCO-TJ Park Award (2008). This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
