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.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Biofilm‐Binding Phages Enhance Biofilm Eradication by Synergistic Photothermal and Photodynamic Therapy

Advanced Science, EarlyView.
Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...
