A Biocompatible Dual‐Sided Hernia Mesh with Side‐Specific Properties
Bibliographic record
Abstract
Abstract Polypropylene (PP) based hernia mesh often shows multiple post‐surgery complications due to lack of biocompatibility, poor cell attachment, and unwanted tissue adhesion. These limitations can be addressed by material designing and surface modification of a mesh with side‐specific properties such as the visceral side (facing intestine) with low protein and cell attachment and the parietal side (facing incision) with improved cell attachment properties for normal healing. However, the development of dual‐sided mesh is very challenging because of its porous structure. Herein, a dual‐sided biocompatible mesh with protein anti‐adsorption and cell attachment properties on two different sides is developed by grafting highly hydrophilic 2‐methcryloyloxyethyl phosphorylcholine polymer (PMPC) on the plasma‐activated visceral side, while the parietal side is coated with bioactive chitosan and functionalized nanodiamond (Chi/FND) using a temporary polyvinyl alcohol (PVA) mold. The PMPC‐grafted side demonstrated excellent resistance to protein adsorption (96% reduction compared to PP) and cell attachment. However, the bioactive coating on the parietal side has significantly improved cell attachment and proliferation properties. In addition, both sides confirmed the presence of the respective biomaterials after an accelerated degradation study for 28 days. Hence, the newly developed dual‐sided mesh by semi‐solid polymer mold (SSPM) method is a promising candidate to address the long‐existing multiple issues of hernia mesh.

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.
