abstract Precise measurements of local transversal Young's moduli of as-grown and annealed nanotubes of diphenylalanine have been performed by mechanical nanoindentation. Evaporation of water from the nanochannels leads to pronounced reduction of the values' dispersion, and the characteristic value coincides with previous theoretical estimations. The experimental value of longitudinal Young's modulus measured at polar surface of vertically aligned bundle of nanotubes is reported for the first time.
