Microscopic solar panels could help shape 3D-printed biological tissue
By Ty Tkacik
Bioprinting uses living cells and molecular signals to produce biological tissues and even whole organs, building them layer by layer in the lab. To keep the bioink, or blend of cells and materials that power this printing, correctly aligned to grow a target tissue, researchers use electricity. However, this typically requires bulky electronic interfaces and invasive wiring. A team led by Penn State engineers has cut the cables, illuminating the first steps towards cell alignment control using miniature solar panels.
