Prof. ZHANG Yong’s team has developed a new method to enhance the free electron concentration and electrical conductivity of MXene by modifying their surface terminal groups, significantly improving the photothermal conversion efficiency to 91.66% under 808nm laser irradiation. A photothermal woundplast with ultra-low MXene content is developed based on the reduced MXene, exhibiting a high bacterial kill rate. As a proof of concept for chronic wound treatment, the light-triggered woundplast can effectively kill 91.39% of Staphylococcus aureus. Reduced MXene has a strong affinity for reactive oxygen species (ROS) and efficient electron transfer for ROS scavenging, mimicking the function of natural antioxidant enzymes, and holds promise for addressing key challenges in anti-inflammatory, antioxidant, and tissue repair applications. This work not only shows an effective method for tuning the photothermal properties of MXene but also demonstrates its translational application potential.
