Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

open access: yesBMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...
