Light-induced color changing of redox dyes assisted by a photoinitiator for information encryption on hydrogel paper

A simple “ink-pumping” strategy uses free radicals from a commercial photoinitiator to trigger UV-induced color change in methylene blue, enabling secure, rewritable, and multicolor information storage on hydrogel paper.
