Gas sensors have long served critical roles in industrial applications, including monitoring air quality and engine emissions. Analyzing volatile organic compounds in breath to screen for disease markers is a developing application that is being advanced by highly sensitive “homemade” gas sensors, often based on semiconducting oxides, nanomaterials, and two-dimensional materials. That field may advance even more quickly now thanks to a study showing that a titanium carbide MXene . . .
