“…Not only that, the composite material can also reduce the expression of the virulence factors of Staphylococcus aureus hemolysin and thrombin, inhibit the formation of staphylococcus aureus biofilm, and avoid the generation of drug resistance. 104 In summary, the polymers not only modify BP and increase its stability, but also enhance the antibacterial properties of the material through its own antibacterial properties and synergistic photothermal and photodynamic properties.…”

Antibiotics are the most commonly used means to treat bacterial infection at present, but the unreasonable use of antibiotics induces the generation of drug-resistant bacteria, which causes great problems for their clinical application. In recent years, researchers have found that nanomaterials with high specific surface area, special structure, photocatalytic activity and other properties show great potential in bacterial infection control. Among them, black phosphorus (BP), a two-dimensional (2D) nanomaterial, has been widely reported in the treatment of tumor and bone defect due to its excellent biocompatibility and degradability. However, the current theory about the antibacterial properties of BP is still insufficient, and the relevant mechanism of action needs to be further studied. In this paper, we introduced the structure and properties of BP, elaborated the mechanism of BP in bacterial infection, and systematically reviewed the application of BP composite materials in the field of antibacterial. At the same time, we also discussed the challenges faced by the current research and application of BP, which laid a solid theoretical foundation for the further study of BP in the future.

“… 9 Black phosphorus (BP), a rising star in the family of two‐dimensional (2D) nanomaterials, has captured significant interest from researchers due to its unique photocatalytic properties, excellent biocompatibility, considerable biodegradability and antimicrobial capabilities. 10 Unlike other 2D nanomaterials like graphene, the exfoliated black phosphorus nanosheets (BPNSs) feature a larger surface‐to‐volume ratio and a puckered honeycomb lattice structure, which endow BP with superior physicochemical properties. 11 Its thickness‐dependent band gap ranging from 0.3 to 2.0 eV, high carrier mobility and broad NIR absorption allow BP nanostructures to exhibit exceptional photothermal and photodynamic properties.…”

Bacterial infection is the most common complication in wound healing, highlighting an urgent need for the development of innovative antibacterial technologies and treatments to address the growing threats posed by bacterial infections. Black phosphorus nanosheets (BPNSs), as a promising two‐dimensional nanomaterial, have been utilized in treating infected wounds. However, BP's limited stability restricts its application. In this study, we enhance BP's stability and its antibacterial properties by anchoring gallium ions (Ga3+) onto BP's surface, creating a novel antibacterial platform. This modification reduces BP's electron density and enhances its antibacterial capabilities through a synergistic effect. Under near‐infrared (NIR) irradiation, the BP/Ga3+ combination exerts antibacterial effects via photothermal therapy (PTT) and photodynamic therapy (PDT), while also releasing Ga3+. The Ga3+ employ a ‘Trojan horse strategy’ to disrupt iron metabolism, significantly boosting the antibacterial efficacy of the complex. This innovative material offers a viable alternative to antibiotics and holds significant promise for treating infected wounds and aiding skin reconstruction.
