Conductive Hydrogel Can Sense Oxygen and Guide Cell Behaviour
Researchers have created a conductive hydrogel, PEDOT:sGAGh, that mimics the extracellular matrix while sensing oxygen and electrically regulating growth‑factor release. By polymerizing less than 1 wt % PEDOT within a sulfated glycosaminoglycan hydrogel, they achieved a 95 wt % water‑rich, soft material with dual ionic‑electronic conductivity. The platform demonstrated voltage‑controlled VEGF retention for vascular cells and NGF release for neurite outgrowth, and it functioned as an oxygen sensor integrated into an organic electrochemical transistor. The authors present this as an early step toward electronic extracellular matrices for biohybrid circuits.
