Polyelectrolyte-based physical adhesive hydrogels with excellent mechanical properties for biomedical applications
Bibliographic record
Abstract
Physically crosslinked hydrogels were synthesized by copolymerization of acrylamide and acrylic acid monomers in the presence of cationic polyelectrolyte polydimethyldiallylammonium chloride. The fully physically crosslinked hydrogel showed good mechanical properties and good adhesion with a variety of substrates. These advantages can be attributed to the homogeneous distribution of crosslinking points due to hierarchical hydrogen bonds and electrostatic attractions in the hydrogel networks. Furthermore, these non-covalent bonds provided an effective pathway to dissipate energy. The mechanical properties of the hydrogels can be easily tuned by changing the chemical composition and ratio of monomers. We further showed that the transparent hydrogels were cytocompatible, and can be used for biomedical applications, including pH-triggered small molecule delivery and hydrogel-based hybrids for detecting doses of radiotherapy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
