The SnO2 nanowire-networked polyurethane fiber, covered with (1H,1H,2H,2H-heptadecafluorodec-1-yl) phosphonic acid-coated Al2O3 nanoparticles, can reliably detect ultraviolet (UV) intensity even when exposed to liquids. This innovative development by Taekyung Lim, Sanghyun Ju, and their co-workers is detailed in article number 1901015, showcasing its potential for stable UV detection in various environments. -Journal cover picture by scapiens
