    Light-activated ink developed to remotely control cardiac tissue to repair the heart
    Optoelectronically active bioink composition and printing. (A) Schematic of bioprinting combining μ-solar cells and GelMA and then seeding with CMs. (B) Photographs of the bioprinting process (i, ii, and iii) of the optoelectronic heart (atria and ventricles) along with a side view. Inset shows the model heart with the printed portion in blue and the remainder of the heart in gray. (C) Example of in vivo implantation of a printed optoelectronically active tissue and correction of arrhythmic beating. Credit: Science Advances (2025). DOI: 10.1126/sciadv.adt7210

    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...
