Abstract
Benefiting from the remarkable developments of nanotechnology, a variety of two-dimensional (2D) nanomaterials (e.g., graphene, molybdenum disulfide, black phosphorous, and so on) and their nanohybrids have been readily produced in previous decades for their fascinating physicochemical properties and innovative applications in various fields. Very significantly, these 2D nanostructured materials have ultrathin thickness and thickness-dependent bandgaps to greatly absorb visible and infrared light for the subsequent generation of considerable heat (i.e., high-efficiency photothermal conversion), which has successfully been utilized in photothermal therapies for ablating tumor cells and pathogenic bacteria. In this chapter, typical 2D nanosystems with excellent photothermal properties are summarized, mainly focusing on the important advances achieved in the past five years. Furthermore, the merits and disadvantages of different types of 2D nanomaterials are discussed at the end of the chapter in terms of their potential for better photothermal applications in future developments.
