An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy

Advanced Healthcare Materials, EarlyView.
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

Wound Geometry Determines Whether Aligned‐Fiber Scaffolds Accelerate or Impede Diabetic Wound Healing: A Biased Random Walk Analysis

Advanced Healthcare Materials, EarlyView.
Wound closure is governed by geometry‐orientation coupling: aligned fibers speed migration along their axis but hinder perpendicular advance. In vivo diabetic wound experiments with composition‐matched fibrin, combined with an anisotropic diffusion (biased random‐walk) model, quantify this trade‐off and generate a healing landscape.
