Abstrakt: With the aim of healing challenging skin wounds, electro-responsive click-hydrogels made of hyaluronic acid (clickHA) crosslinked with a modified polyethylene glycol precursor (PEG) were prepared by semi-interpenetrating a conducting polymer, poly(hydroxymethyl-3,4-ethylenedioxythiophene) (PEDOT-MeOH) by oxidative polymerization. The porosity and pore size of the mixed hydrogel, clickHA/PEDOT-MeOH, were both higher than those determined for the hydrogel without PEDOT-MeOH, while a honeycomb-like morphology with PEDOT-MeOH covering the pore walls was observed. Although such PEDOT-MeOH-induced changes did not influence the water absorption capacity of clickHA, they drastically affected the mechanical and electrochemical behavior. More specifically, the semi-interpenetration of PEDOT-MeOH into clickHA resulted in an increase of the Young's modulus, the compressive strength and, especially, the electrochemical activity. The biocompatibility and the potential for skin regeneration of clickHA/PEDOT-MeOH were preliminary assessed using viability and wound-healing assays with epithelial cells. Not only is the conducting hydrogel formulation biocompatible, but also promotes efficient cell migration by electrostimulation using a small voltage (0.5 V) for a short time (15 min). Thus, in just 1 h the wound gap was repaired, and a homogeneous monolayer of migrated cells was formed.
