Metallic phase enabling MoS₂ nanosheets as an efficient sonosensitizer for photothermal-enhanced sonodynamic antibacterial therapy.

ABSTRACT: Two-dimensional (2D) transition metal dichalcogenide (TMD) nanosheets (e.g., MoS₂) with metallic phase (1T or 1T´ phase) have been proven to exhibit superior performances in various applications as compared to their semiconducting 2H-phase counterparts. However, it remains unclear how the crystal phase of 2D TMD nanosheets affects their sonodynamic property. In this work, we report the preparation of MoS₂ nanosheets with different phases (metallic 1T/1T´ or semiconducting 2H) and exploration of its crystal-phase effect on photothermal-enhanced sonodynamic antibacterial therapy. Interestingly, the defective 2D MoS₂ nanosheets with high-percentage metallic 1T/1T´ phase (denoted as M-MoS₂) present much higher activity towards the ultrasound-induced
