ZHAO Yuanjin and colleagues from the state key laboratory of bioelectronics at China's Southeast University have developed a "heart-on-a-chip" device to mimic the beat and contraction of cardiac muscle cells in vitro. The concept is based on a colored hydrogel which is injected into a chip bearing the heart muscle cells which shows color changes upon contraction of the cells. When medication is added, the conditions of the cardiac muscle cells can be monitored through the color-changing hydrogel.
