Abstract

fetched live from OpenAlex

A novel bi-template induced co-assembly method was employed to fabricate biomimetic bone substitute materials, collagen (COL)-fibroin/hydroxyapatite (COL-SF/HA) composite by using a combination of Type I COL and silk fibroin (SF) molecular templates. As a control, COL/HA and SF/HA composites were also synthesized via single-template assembly technology. The structure and morphology of the resulting assembly composites were investigated by X-ray diffractometer, Fourier transform infrared spectra, transmission electron microscope, and thermogravimetric analysis. Their sizes and size distributions were measured by DLS. The results indicated that the mineral phases in COL-SF/HA, COL-HA, and SF-HA composites were needle-like nano-HA crystals. In comparison to those in COL-HA and SF-HA, the mineral phase in COL-SF/HA displayed smaller size and more narrow distribution. Of all above biomimetic composites, the HA was well assembled with molecular template(s), and the organic content of the composite was about 12%-20%, which was quite similar to the natural bone in composition. CD and SDS-PAGE were used to examine the secondary structure and subunit composition of template proteins. The results revealed that the spatial structure of co-assembly template proteins played a pivotal role in controlling and regulating HA crystal nucleation and growth. Based on the experimental results above, a possible co-assembly mechanism for the HA growing on fibrous bi-template proteins was suggested.

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.
