Multifunctional Thiolated Hyaluronic Acid‐graft‐PEDOT Dressing With Antifouling, On‐Demand Drug Delivery and Electrical Stimulation for Wound Healing

Advanced Healthcare Materials, EarlyView.
A multifunctional P(EDOT‐co‐EDOT‐g‐THA) dressing acts as a dynamic biointerface integrating antifouling capability, on‐demand drug delivery, and electrical stimulation. It achieves electrochemically triggered thiolated hyaluronic acid (THA) release while modulating cellular responses for wound healing application.

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

Advanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.
