Purpose of the Study:
- To develop a novel bilayer hydrogel system for 3D multistage information encryption with self-erasure capabilities.
- To explore the synergistic deformation and fluorescence color (SDFC) change for enhanced information security.
Main Methods:
- Design of a bilayer hydrogel comprising a shape-deformable layer and an aggregation-induced emission (AIE) fluorescent layer.
- Ionoprinting of fluorescence information using electrostatic interactions and dynamic covalent bonds.
- Utilizing pH-responsive SDFC change for information encoding and retrieval.
Main Results:
- The bilayer hydrogel exhibits pH-responsive synergistic deformation and fluorescence color change.
- Information is encrypted in 3D by the hydrogel's shape configuration and background fluorescence.
- Multistage decryption is achieved through differential fluorescence fading rates, followed by self-erasure.
Conclusions:
