One-Step Synthesis of a Fluorescent Phospholipid−Hydrogel Conjugate for Driving Self-Assembly of Supported Lipid Membranes
Bibliographic record
Abstract
We have synthesized a phospholipid−hydrogel conjugate that appears to drive the self-assembly of lipid membranes. A one-step radical polymerization synthesis of the conjugate was devised using lipid anchors that contain a fluorescent marker and a reactive vinyl group. The anchors preferentially located at oil−water interfaces during hydrogel formation and through their vinyl groups became covalently attached at the hydrogel surface. X-ray photoelectron spectroscopy and laser scanning confocal microscopy confirmed surface localization of the anchors. Upon mixing the conjugates with liposomes, lipid membranes readily self-assembled around the lipid-modified hydrogel surfaces. Control experiments with anchorless hydrogels indicate that anchors influenced the surface density and morphology of the lipid membranes. The one-step synthesis allows for simple control of surface anchor density and thus potential control of lipid membrane properties; the fluorescent markers facilitate anchor quantitation and further membrane interaction studies. Potential applications include high throughput drug screening, diagnostics, cell models, and drug delivery.

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.
