Enhanced MC3T3 preosteoblast viability and adhesion on polyelectrolyte multilayer films composed of glycol‐modified chitosan and hyaluronic acid
Bibliographic record
Abstract
Layer-by-layer polyelectrolyte films made of the naturally derived polysaccharides chitosan (CHI) and hyaluronic acid (HA) constitute a well-studied system for the development of cell-responsive biointerfaces. However, many cell lines exhibit decreased adhesion to CHI/HA multilayer films, particularly as the number of bilayers is increased. Here, our group demonstrates that films composed of glycol-modified chitosan exhibit significantly improved MC3T3 preosteoblast adhesion and viability compared to corresponding films consisting of unmodified CHI. These differences in cellular adhesion are likely due to differences in surface topography and roughness, as measured via atomic force microscopy (AFM), as well as in film chemistry and the water solubility of the cation, since both types of films exhibited similar: thickness, as measured via quartz crystal microbalance and AFM; wettability, as measured via contact angle; and serum protein adsorption, as measured via the bicinchoninic acid assay.

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.
