Query: Atomic Force Nanoscope   Atomic Force Microscopy (AFM) allows to probe matter at atomic scale by
measuring the perturbation of a nanomechanical oscillator induced by near-field
interaction forces. The quest to improve sensitivity and resolution of AFM has
forced the introduction of a new class of resonators with dimensions well below
the micrometer scale. In this context, nanotube resonators are the ultimate
mechanical oscillators because of their one dimensional nature, small mass and
almost perfect crystallinity, coupled to the possibility of functionalisation,
these properties make them the perfect candidates as ultra sensitive, on-demand
force sensors. However their tiny dimensions make the measurement of the
mechanical properties a very challenging task in particular when working in
cavity free geometry at ambient temperature. By using a highly focused electron
beam, we show that the mechanical response of nanotubes can be quantitatively
measured while approaching to a surface sample. By coupling electron beam
detection of individual nanotubes with a custom AFM we can image the surface
topography of a sample by measuring in real time the mechanical properties of
the nanoresonators. The combination of very small size and mass together with
the high resolution of the electron beam detection method offers unprecedented
opportunities for the development of a new class of Atomic Force Nanoscope
(AFN).
