Facile Fabrication of Injectable Multifunctional Hydrogels Based on Gallium‐Polyphenol Networks with Superior Antibacterial Activity for Promoting Infected Wound Healing

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

Published: Jan. 31, 2025

Multifunctional hydrogels hold significant promise for promoting the healing of infected wounds but often fall short in inhibiting antibiotic-resistant pathogens, and their clinical translation is limited by complex preparation processes high costs. In this study, a multifunctional hydrogel developed combining metal-phenolic networks (MPNs) formed tannic acid (TA) gallium ions (Ga3⁺) with chitosan (CS) through simple one-step method. The resulting CS-TA-Ga3⁺ (CTG) cost-effective exhibits desirable properties, including injectability, self-healing, pH responsiveness, hemostasis, antioxidant, anti-inflammatory, antibacterial activities. Importantly, CTG are effective against pathogens due to unique mechanism Ga3⁺. vivo studies demonstrate that promotes follicle formation collagen deposition, accelerating blood loss, suppressing bacterial growth, modulating inflammatory microenvironment. These findings highlight hydrogel's potential as an advanced translational dressing enhancing wounds.

A Heterojunction Piezoelectric Antimicrobial Asymmetric Hydrogel for Dynamic Wound Healing and Monitoring

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 21, 2025

Abstract Dynamic wound care presents significant challenges for conventional dressings due to the complex environment and high‐frequency motion associated with such injuries. In this study, a multifunctional photo‐crosslinked piezoelectric hydrogel (OAPS) is developed, incorporating heterojunction Se‐doped KH570 modified BaTiO 3 nanoparticles (Se‐BT570 NPs) as core component, designed address antimicrobial monitoring needs in care, particularly at sites movement. The OAPS effectively utilizes inherent dynamic wounds, enhancing efficacy enabling real‐time of human health statuses. This achieved through synergistic effects properties nano‐heterostructures that enable self‐driven charge transfer. Such integration allows dual applications both diagnosis treatment. Experimental results demonstrated exhibits excellent mechanical strength adhesive properties, adapting motion. Additionally, can be activated by environments perform functions, significantly accelerating healing an rate 99.75%. study highlights potential nanomaterials healing, offering promising strategy managing complex, care.
