Light-activated ink developed to remotely control cardiac tissue to repair the heart

Researchers from Mass General Brigham and collaborating institutions have developed a non-invasive approach to manipulate cardiac tissue activity by using light to stimulate an innovative ink incorporated into bioprinted tissue. Their goal is to develop a technique that can be used to repair the heart. Their findings in preclinical models, published in Science Advances, show the transformative potential of non-invasive therapeutic methods to control electrically active tissues.
