Abstract

fetched live from OpenAlex

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.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
