Luminescent Squid‐Inspired Phosphorescent Hydrogels with Persistent Afterglow and Dynamic Information Display
Bibliographic record
Abstract
Abstract A critical challenge in multifunctional room‐temperature phosphorescent (RTP) hydrogels is the balance between the persistent afterglow and the editable phosphorescent information. Inspired by the Hawaiian bobtail squid ( Euprymna scolopes ), which modulates bioluminescence through symbiotic bacterial storage and release, a biomimetic RTP hydrogel system is introduced that overcomes this limitation. The hydrogel, synthesized via polymerization of acrylic acid (AA) with diethylenetriamine (DETA), followed by Ca 2+ coordination with COO − in polyacrylic acid (PAA) chains, exhibits remarkable phosphorescence (afterglow > 6.5 s) and three synergistic functionalities: 1) Dynamic information re‐editability via water erasing and salt printing for real‐time information programming; 2) Thermomechanical responsiveness enabling reversible stiffness modulation and thermal concealment of photonic information; 3) Self‐healing through dynamic hydrogen bonding, facilitating dynamic reconfiguration of luminescent patterns. This RTP hydrogel establishes a robust platform for the edition of information, which emphasizes the potential of bioinspired strategies for advancing intelligent materials in bioimaging, flexible displayers, and information encryption.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
