Nanosprings are potentially superior in sensing capabilities to all presently existing nanostructures because of their extremely large, and accessible, surface area (400 m2/g). A Nanospring has up to 1500 times more surface area than the footprint of its root on the substrate, which is 10-20 times larger compared with nanowires. Nanosprings are formed at 350°C and can be deposited on virtually any substrate. In addition, Nanospring growth is compatible with microelectronics processing. Consequently, they can be post-coated with a variety of conducting, semiconducting, or insulating materials, as well as any combination thereof to build hierarchical nanostructures. Another advantage of Nanosprings is the mats can be patterned prior to growth in order to achieve select geometric patterns: area of coverage can be precisely determined by the lithographic pattern of the catalyst. The versatility of this material allows unprecedented design flexibility with which to successfully develop basic elements for nanoscale electronics. In this paper we discuss the potential application of Nanospring mats as chemiresistors.
