53_23b/2014Back Cover: Molecular Ionization from Carbon Nanotube Paper (Angew. Chem. Int. Ed. 23/2014)

A piece of paper that is impregnated with multi-walled or single-walled carbon nanotubes generates ions from diverse analytes at voltages as low as 3 V, as T. Pradeep et al. show in their Communication on page 5936 ff. This miniaturized ion source is held in front of a mass-spectrometer inlet to collect the mass spectrum. Common pesticides from the surface of an orange, active molecules from tablets, and a variety of analytes, such as amino acids, can been characterized.
