Dual-imaging-mode smart hydrogel information platform for illumination-independent covert decryption and read

Junjie Wei, Long Li, Rui Li, Qingquan Liu, Zejun Yan & Tao Chen
Smart hydrogel with color responsiveness is envisioned as one of the most promising materials for advanced information encryption and decryption platform, but the illumination-dependent way of decrypting and reading information leads to the worrying of concealment in some particular scenarios. Herein, we proposed a smart hydrogel information platform with dual imaging modes by utilizing the accompanying behaviors in transparency change and heat releasing after crystallization of supercooled solution. For this smart hydrogel information platform, the...
