Biomimetic Mineralization Induced by Fibrils of Polymers Derived from a Bile Acid
Bibliographic record
Abstract
A polymer containing bile acid pendant groups was prepared by free-radical polymerization of the 3alpha-methacrylate derivative of cholic acid. The polymer formed fibrils of about 1 nm in diameter in aqueous media and further assembled into bundles or lamella plates, as observed by transmission electron microscopy. After immersing the fibrils in simulated body fluid with ion concentrations equivalent to those in human plasma, plate-like crystals formed on the surface of the fibril assembly. The diffraction pattern corresponding to the (001) plane of hydroxyapatite was identified by transmission electron microscopy and selected area electron diffraction. The plate-like, single crystal hydroxyapatite formed on such a polymeric assembly may be useful in the matrix design for biomimetic mineralization and in the development of scaffold materials for hard tissue engineering.

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.
