A Thermoreversible Poly(Choline Phosphate) Based Universal Biomembrane Adhesive
Bibliographic record
Abstract
A new monomer, 2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl methacrylate (AEO4 MA), and its direct atom transfer radical polymerization (ATRP) into poly(AEO4 MA), then "clicked" with prop-2-ynyle choline phosphate (CP) to produce a poly(choline phosphate) are described. This polymer exhibits a lower critical solution temperature (LCST) at ≈ 32 °C, and provides a universal thermally reversible biomembrane adhesive, which can rapidly both bind to any mammalian cell membrane and internalize into the cytoplasm of nucleated cells below the LCST. Moving above the LCST reverses cell surface binding. The use of ATRP implies that such polymers can be applied to modify the surfaces of a wide range of biomaterials. The capacity to bind and immobilize cells at room temperature and release them above the LCST should be particularly useful for in vitro cell manipulation and tissue engineering applications.

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.
