Functionalized carbon nanotubes possess promising electronic properties, but their poor solubility often hampers their use in practical devices. Timothy M. Swager and colleagues at MIT have found a way around this problem: a solvent-free method to process nanostructured carbon materials. And they have used it to create gas and vapor sensors on paper (Proc. Natl. Acad. Sci. USA 2013, DOI: 10.1073/pnas.1307251110). . . .
