Au Nanorods Activate Zn2+/Ag+ Mediated Anti-inflammatory for Enhanced Methicillin-Resistant Wound Repair via Bionic Claw Microneedles
Wound infections caused by methicillin-resistant Staphylococcus aureus (MRSA) have attracted wide attention owing to acidic biofilms and the alkaline wound microenvironment, which result in hindering wound healing. In this work, we prepared an acid–base responsive bionic claw microneedle (MN) loaded with Au@ZnO/Ag (AZA) core–shell nanoparticles, which shows excellent photothermal transition and antibacterial activity. In the acidic medium of the biofilm, 97.98% of bacteria were successfully eradicated under mild thermal conditions (≤40 °C). In the alkaline wound microenvironment, inflammatory cytokines were inhibited by Ag+. Vascular endothelial growth factor expression was promoted by trace Zn2+, and the wound healing rate increased by up to 24.02% compared to the control group. The bionic claw MN loaded with AZA effectively combines the benefits of low-temperature acidic sterilization and alkaline anti-inflammatory activity. The promotion of MRSA infected wound healing through the synergistic effect of released Zn2+/Ag+ and the mild thermal impact showcases new avenues for clinical treatment.
期刊介绍：
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times.
