Polyurethane (PU)-derived photoactive and copper-free clickable surface based on perfluorophenyl azide (PFPA) chemistry
Bibliographic record
Abstract
The anchoring and capturing roles of perfluorophenyl azide (PFPA) were combined to produce a universal polyurethane (PU)-derived photoactive surface platform (PU-1-PFPA). The resultant platform was confirmed by contact angle, attenuated total reflectance Fourier transform infrared (ATR FT-IR) spectroscopy, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) analyses. Upon UV light activation, native heparin was coupled directly onto PU-1-PFPA to yield a substrate with antithrombogenic properties. The same level of antithrombogenic activity was achieved when the recovered heparin was photo-coupled onto PU-1-PFPA. In addition, at room temperature and in the absence of copper catalysts, PU-1-PFPA achieved oriented immobilization of functional moieties bearing an alkynyl functional group.

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.
