“…In terms of type-II photochemical reactions, the E T1 of all PSs were higher than 0.98 eV that corresponded to the lowest energy required to promote 3 O 2 to 1 O 2 , indicating that all PSs could sensitize the generation of 1 O 2 via direct energy transfer pathway. 40 Taken together, in contrast to unbridged D−A type PSs, azo-bridged trans-compounds exhibited decreased ΔE ST , which favored enhanced generation of both type-I and type-II ROS via efficient ISC. For azo-bridged cis-compounds, the ΔE ST was increased and the corresponding ξ ST was decreased.…”

“…Hence, the photothermal mechanisms of MXenes, mainly accounting for photo-induced antibacterial properties, are of tremendous importance and need to be described in detail. Interestingly, compared with sole PTT, various combined therapies with less light energy consumption show superior antibacterial potential and cost-effectiveness, achieving a desired synergistic effect [ 107 , 108 ]. In this section, the photothermal properties of MXenes and their derivative antibacterial mechanisms will be systematically reviewed.…”

Highlights Fabrication, characterizations and photothermal properties of MXenes are systematically described. Photothermal-derived antibacterial performances and mechanisms of MXenes-based materials are summarized and reviewed. Recent advances in the derivative applications relying on antibacterial properties of MXenes-based materials, including in vitro and in vivo sterilization, solar water evaporation and purification, and flexible antibacterial fabrics, are investigated. Abstract The pernicious bacterial proliferation and emergence of super-resistant bacteria have already posed a great threat to public health, which drives researchers to develop antibiotic-free strategies to eradicate these fierce microbes. Although enormous achievements have already been achieved, it remains an arduous challenge to realize efficient sterilization to cut off the drug resistance generation. Recently, photothermal therapy (PTT) has emerged as a promising solution to efficiently damage the integrity of pathogenic bacteria based on hyperthermia beyond their tolerance. Until now, numerous photothermal agents have been studied for antimicrobial PTT. Among them, MXenes (a type of two-dimensional transition metal carbides or nitrides) are extensively investigated as one of the most promising candidates due to their high aspect ratio, atomic-thin thickness, excellent photothermal performance, low cytotoxicity, and ultrahigh dispersibility in aqueous systems. Besides, the enormous application scenarios using their antibacterial properties can be tailored via elaborated designs of MXenes-based materials. In this review, the synthetic approaches and textural properties of MXenes have been systematically presented first, and then the photothermal properties and sterilization mechanisms using MXenes-based materials are documented. Subsequently, recent progress in diverse fields making use of the photothermal and antibacterial performances of MXenes-based materials are well summarized to reveal the potential applications of these materials for various purposes, including in vitro and in vivo sterilization, solar water evaporation and purification, and flexible antibacterial fabrics. Last but not least, the current challenges and future perspectives are discussed to provide theoretical guidance for the fabrication of efficient antimicrobial systems using MXenes.

“…, under light irradiation, giving them a better PDT efficacy than Type-II PSs under low-O 2 conditions. 32–35 Accordingly, it is natural for us to try to expand the applicable scope of the “polymerization-enhanced photosensitization” effect, to see whether or not it can be used in other types of conjugated polymer, and whether it can be used for designing Type-I PSs.…”
