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

Degradable Donor‐Acceptor Polymeric Mixed Ionic‐Electronic Conductors for Transient Electronics
Advanced Materials Technologies, EarlyView.Here, we report degradable donor–acceptor (D–A) polymeric mixed ionic‐electronic conductors for transient electronics. We take a systematic side chain engineering approach to elucidate how molecular‐level modifications of donor–acceptor (D–A) polymer structures can satisfy demands that are often conflicting: degradability, charge carrier transport, and

Schottky Barrier Engineering in n‐Type Organic Source‐Gated Transistors Enabling High Conductance
Advanced Materials Technologies, EarlyView.This study introduces a modified source electrode architecture for n‐type organic source‐gated transistors (OSGTs). By integrating Schottky and Ohmic contact regions, the design achieves a thinner depletion envelope, enhancing mobility nearly tenfold and reducing threshold voltage.
