Conductive, adaptive, multifunctional hydrogel combined with electrical stimulation for deep wound repair

To promote wound healing and solve the limitations of current hydrogel wound dressings—that is, they can only cover the surface of deep wounds, leaving a cavity underneath that blocks endogenous and external electrical current conduction—we designed an adaptive conductive hydrogel that spontaneously adapted to the shape of wounds. We prepared this hydrogel by including tannic acid (TA) and human-like collagen (HLC) into polyvinyl alcohol (PVA)...
