Abstract 

Two-dimensional (2D) materials with a thickness of a few nanometers or less can be used as single sheets due to their unique properties or as building blocks, to assemble a variety of structures. The family of two-dimensional (2D) transition metal carbides and nitrides, MXenes, has been expanding rapidly since the discovery of Ti3C2 in 2011 [1]. More than 20 different MXenes have been synthesized, and the structure and properties of numerous other MXenes have been predicted using density functional theory calculations [2]. MXenes’ versatile chemistry renders their properties tunable for a large variety of applications. Oxygen or OH terminated MXenes, such as Ti3C2O2, are promising candidates for biomedical applications [2].

Antibacterial properties of micrometer-thick titanium carbide (Ti3C2Tx) MXene membranes prepared by filtration on a   polyvinylidene fluoride (PVDF) support have been studied. The bactericidal properties of Ti3C2Tx modified membranes were tested against Escherichia coli and Bacillus subtilis.  The demonstrated antibacterial activity of MXene coated membranes against common waterborne bacteria, promotes their potential application as anti-biofouling membrane in water and wastewater treatment processes, as well as a bactericidal coating. [3] The 2D titanium carbide sheets manifest strong optical absorption in the near-infrared (NIR) around 800 nm. The performance of this material is comparable or even superior to that of state-of-the-art photoabsorption materials, including gold-based nanostructures, carbon nanomaterials, and transition-metal dichalcogenides. Preliminary studies show that the titanium carbide sheets serve as an efficient photothermal agent against tumor cells. [4]
