Wireless Thermoelectric Hydrogel Recreates Biomimetic Electric Field and Angiogenic Signal Accelerating Diabetic Ulcer Repair

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 25, 2025

Abstract Endogenous electric field (EF)‐actuated reepithelization, dermal formation, and growth factors‐induced angiogenesis are crucial for wound healing. It is however, challenging to initiate both endogenous EF factors in diabetic ulcer due severe electrolyte loss hyperglycemia‐resulted endothelial dysfunction. Current therapeutic systems supply electrostimulation by integrating self‐powered conductive materials continue encounter obstacles nondegradability‐induced low biocompatibility anisotropic EF‐resulted limited regeneration. Recombinant also high cost, stability, potential bio‐risk. Herein, a wireless biocompatible thermoelectric hydrogel (HFN) co‐crosslinked biodegradable hyaluronic acid polyether F127 developed achieve effective directional‐EF stimulation. Target‐modified ginseng‐derived exosomes (RGE) further embedded the design of HFN‐RGE enhanced Specifically, recreates biomimetic through “cationic trap” effect trigger robust epithelial fibroblast electrotaxis, meanwhile controlling release precise pro‐angiogenic with unique ability reverse In vivo, demonstrated stimulate reepithelialization, regeneration, nascent vessel network reconstruction. Single‐cell RNA‐seq revealed that activates PPAR signaling‐meditated tissue As such this work provides promising electrical‐biological hybrid system biosafety therapy.

Harnessing Ultrasonic Technologies to Treat Staphylococcus Aureus Skin Infections

Molecules, Journal Year: 2025, Volume and Issue: 30(3), P. 512 - 512

Published: Jan. 23, 2025

The rise of antibiotic-resistant Staphylococcus aureus strains, particularly MRSA, complicates the management skin and soft tissue infections. This review highlights ultrasonic methodologies as adjunctive therapies to combat S. aureus-driven infections prevent progression biofilm formation chronic wounds. Low- high-frequency ultrasound (LFU HFU) demonstrate potential in disrupting biofilms, enhancing drug delivery, promoting repair through cavitation microbubble activity. These approaches integrate frequencies with microbubbles therapeutics, such antibiotics affimers, minimize resistance improve healing. Tailoring bioeffects on structures localized delivery technologies, including microneedle patches piezoelectric systems, presents promising solutions for early intervention structure (SSSIs).
