In addition, sfm detection provides unique information about the physics of nanotube resonators such as the effect of slack in swnt resonators. The reliability of mwnt combined with their low mass and high stiffness make them very attractive for industrial applications like micromechanical circuits . It is shown that carbon nanotubes and graphene are excellent nanomechanical oscillators with unique behaviour. Graphene resonators can behave as perfect beams or they can exhibit a new class of nanoscale eigenmodes. These exotic eigenmodes are the result of the highly non-uniform stress present in the resonator.  it is also shown that swnt are excelent transducers due to their semiconducting properties and it is demonstrated that they can be used as ultra sensitive mass sensors. The measured performances are exceptional. A mass responsivity of 11 hz.Yg^-1 and a mass resolution of 25 zg at room temperature have been measured. By cooling the nanotube down to 5 k in a cryostat, the signal for the detection of mechanical vibrations is improved and corresponds to a resolution of 1.4 zg.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos
