Laser surface texturing of SS316L for enhanced adhesion of HUVECs
Bibliographic record
Abstract
This study investigates the effects of the structured surface on the adhesion, proliferation and alignment of endothelial cells (HUVECs). The chemical state of laser-structured surface was also investigated in comparison with the non-treated surface. A novel design for biomedical applications consisting of parallel chain-like structures was realised on stainless steel surface by laser micromachining. The structures were designed to employ surface topography in the presence of micron and sub-micron features and to avoid intensive surface modification that could compromise the mechanical properties of thin devices like cardiovascular stents. The results showed that the structured surfaces favored the adhesion, proliferation and alignment of HUVECs. The proliferation and the alignment of HUVECs were pronounced when the periodic distance between two consecutive chain-like structures was 25 µm. Moreover, there was no significant difference in chemical composition on the structured surface suggesting that the cell proliferation and alignment were mainly influenced by the surface topography.

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.
