Surface Engineering of Poly(ethylene terephthalate) for Durable Hemocompatibility via a Surface Interpenetrating Network Technique
Bibliographic record
Abstract
Abstract Heparin was covalently bonded on chemically inert PET substrate using a surface modification technique–surface interpenetrating network with the purpose of fabricating long‐lasting biocompatible materials as vascular grafts. FTIR and XPS spectra confirmed the successful heparinization of PET (PET‐Hep). The density of surface‐immobilized heparin as quantified by a colorimetric method could reach 2.4 μg cm −2 (in the reported optimal range: 1.5–3.0 μg cm −2 ). The hemocompatibility of the heparin‐immobilized PET was improved as evidenced by a platelet adhesion test: significantly less platelet adhesion on PET‐Hep (11.60%) than on untreated PET (48.91%). An MTT assay indicated PET‐Hep was nontoxic to human dermal fibroblast cells. After an initial 5.24% loss of heparin from PET‐Hep in the first 14 h immersion in PBS buffer solution, no further leaching of heparin was found.

How this classification was reachedexpand
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.
