A 3D multistage information encryption platform with self-erasure function based on a synergistically shape-deformable and AIE fluorescence-tunable hydrogel

A facile strategy to fabricate an advanced AIE fluorescence-based information encryption platform with self-erasure ability by combining the shape and fluorescence change of the TPE3N 3+ -hydrogel/PAA-hydrogel bilayer hydrogel was demonstrated.
