Mo2C nanosheets decorated with boron dipyrromethene enabling photothermal and photodynamic attributes for highly efficient antibacterials

The advancement of novel MXene materials characterized by heightened stability and remarkable antibacterial attributes has garnered substantial attention in recent research endeavours. In this article, it is first time to prepare boron dipyrromethene (BODIPY) modified Mo 2 C nanosheets (BODIPY-Mo 2 C) via electrostatic interactions to achieve the desirable antibacterial property, enriching by both photothermal and photodynamic effects. The photothermal conversion efficiency of the produced Mo 2 C nanosheets reached to 42.6 %. Furthermore, in the photothermal antibacterial tests against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), both Mo 2 C and BODIPY-Mo 2 C demonstrated 100 % antibacterial efficiency at a concentration of 100 μg·mL −1 . Remarkably, at a lower concentration gradient of 75 μg·mL −1 , BODIPY-Mo 2 C nanosheets showed clearly enhanced antibacterial capabilities compared to pure Mo 2 C, underscoring the efficacy of BODIPY in boosting the antibacterial performance of Mo 2 C.
