Abstract
Antibacterial functionality in clinical orthopedic implants remains an area needing improvement. This study presents a novel, stepwise antibacterial method to prevent implant infections. First, a Mg 3 ZnCa (ZX31) alloy was selected for its biodegradable properties, then its poor corrosion resistance was enhanced using plasma electrolytic oxidation (PEO). Next, electrospun nanofibers loaded with the antibiotic cefiderocol were applied to the PEO-coated surface. Finally, bacteriophages were immobilized onto the nanofibers. The structure and antibacterial performance of each step were characterized, including electron microscopy imaging of the immobilized phages. Antibacterial testing against Escherichia coli demonstrated that phage–antibiotic co-release achieved complete bacterial eradication within one hour, compared to eight hours for cefiderocol-loaded fibers alone. Additionally, magnesium corrosion contributed to sterilization after ten hours. These results show the strong synergistic potential of combining magnesium degradation, antibiotic delivery, and phage therapy to prevent early-stage infections on orthopedic implants, offering a promising route for future clinical applications.

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 it
