Alone, naked, and with their eyes covered for protection: this is how newborns lie in incubators when they are being treated for jaundice. Irradiation with blue light in an incubator is necessary because toxic decomposition products of the blood pigment hemoglobin are deposited in the skin in newborns with jaundice. Researchers of the Empa division Biomimetic Membranes and Textiles have now significantly improved the not-so-child-friendly procedure by combining the treatment with the needs of the newborns: The team, led by Luciano Boesel, developed illuminated pajamas for babies that turn the treatment into a wellness experience.
