Plasma polymer films to regulate fibrinogen adsorption: Effect of pressure and competition with human serum albumin
Bibliographic record
Abstract
Low‐pressure plasma‐deposited C2H4 and C4H6 films containing N‐ and O‐groups, are used to regulate fibrinogen (Fg) adsorption in the presence of human serum albumin (HSA), with the long‐term intention of achieving control over platelet activation. This work includes a study of the effect of pressure on the films’ surface chemistry, stability in phosphate buffer solution (PBS), and Fg adsorption. Tribometry tests against a polyethylene surface, in PBS, indicated that N‐rich films were more susceptible to wear than the O‐rich coating. Adsorption kinetics showed a distinct peak which suggested a multilayer formation of HSA owing to adsorption from a highly concentrated solution. Results conclude that Fg adsorption in the presence of a high concentration of HSA can still be regulated by the careful choice of film surface chemistry.

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.
