The elastic mechanical properties of one-dimensional nanostructures are considered, with an emphasis on the use of contact-resonance atomic force microscopy methods to determine elastic moduli. Various methods used to determine elastic moduli of one-dimensional nanostructures are reviewed before detailed consideration of the experimental and analytical methods used in contact-resonance atomic force microscopy. The variations of the elastic moduli of ZnO and Te nanowires with nanowire diameter are presented and interpreted in terms of core-shell models of nanowire structure. The importance of accurate and precise methods for measuring the mechanical properties of nanostructures, and how those methods need to be adjusted for one-dimensional nanostructures, is emphasized.
