Metal oxides are the most commonly used materials for chemical sensors, originally in form of thick-films. Single-crystalline one-dimensional nanostructures have considerable advantages: high surface-to-volume ratio, readily achieved reduced lateral dimensions, and their high degree of purity and crystallinity. These characteristics permit a variety of gas sensor designs, such as single wire, self-heating devices and photoactivation. Despite these advantages, large-scale integration has still not been achieved, and two-dimensional nanostructures still merit study and research.
