Abstract

fetched live from OpenAlex

Next generation wound care technology\ncapable of diagnosing wound\nparameters, promoting healthy cell growth, and reducing pathogenic\ninfections noninvasively would provide patients with an improved standard\nof care and accelerated wound repair. Temperature is one of the indicating\nbiomarkers specific to chronic wounds. This work reports a hybrid,\nmultifunctional optical material platformnanodiamond (ND)–silk\nmembranes as biopolymer dressings capable of temperature sensing and\npromoting wound healing. The hybrid structure was fabricated through\nelectrospinning, and 3D submicron fibrous membranes with high porosity\nwere formed. Silk fibers are capable of compensating for the lack\nof an extracellular matrix at the wound site, supporting the wound-healing\nprocess. Negatively charged nitrogen vacancy (NV<sup>–</sup>) color centers in NDs exhibit optically detected magnetic resonance\n(ODMR) and act as nanoscale thermometers. This can be exploited to\nsense temperature variations associated with the presence of infection\nor inflammation in a wound, without physically removing the dressing.\nOur results show that the presence of NDs in the hybrid ND–silk\nmembranes improves the thermal stability of silk fibers. NV<sup>–</sup> color centers in NDs embedded in silk fibers exhibit well-retained\nfluorescence and ODMR. Using the NV<sup>–</sup> centers as\nfluorescent nanoscale thermometers, we achieved temperature sensing\nin 25–50 °C, including the biologically relevant temperature\nwindow, for cell-grown ND–silk membranes. An enhancement (∼1.5×\non average) in the temperature sensitivity of the NV<sup>–</sup> centers was observed for the hybrid materials. The hybrid membranes\nwere further tested <i>in vivo</i> in a murine wound-healing\nmodel and demonstrated biocompatibility and equivalent wound closure\nrates as the control wounds. Additionally, the hybrid ND–silk\nmembranes exhibited selective antifouling and biocidal propensity\ntoward Gram-negative Pseudomonas aeruginosa and Escherichia coli, while no effect\nwas observed on Gram-positive Staphylococcus aureus.

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.
