Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Interphase Self‐Optimization Enables Stable Magnesium Anode in Hydrogel Electrolyte

Advanced Materials, EarlyView.
Based on a MgCl2 hydrogel electrolyte, we identify a tridentate chelant additive to construct a magnesium oxychloride interphase on Mg metal anodes. This self‐optimized interphase enables low‐resistance Mg2+ stripping/plating, resulting in much elongated cycling life of 600 h with 0.24 V nucleation overpotential.

Electrochemically Engineered PEDOT:PSS/MXene Composite Electrode for the Label‐Free Procalcitonin Detection

Advanced Materials Interfaces, EarlyView.
Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.
