Researchers at the Technical University of Munich (TUM) have developed a coating using proteins and bacteria that could enable the development of T-shirts that warn of excessive sun exposure or labels that reveal damage to light-sensitive materials. The coating reliably detects contact with UV-A radiation, is bio-based, and could open the door to a wide range of new materials that draw on the biological functions of cells.
