MXenes are emerging as a promising tool to capture and degrade viruses, such as SARS-CoV-2. MXenes are light-to-heat converters that are capable of adsorbing virus and inactivating it by applying light. Some MXenes are antibacterial as well, likely due to their combined hydrophilic property and charge transfer ability. They are particularly promising for the development of coatings that are capable of capturing and inactivating viruses on face masks and other PPE. MXenes can also regenerate dialysate by removing toxins that build up in the setting of kidney failure - they may be able to address key limitations of current ambulatory dialysis systems by offering efficient urea adsorption, small size, and lightweight.
