“…In this work in contrast to our previous one, the amplitude‐frequency characteristics and the resonant frequencies of the NMO were measured automatically. On the first stage, to measure amplitude of the CNW oscillation the electron beam was scanning along one line near CNW free end perpendicular to CNW.…”

“…In ref. , we used the NMO in the form of CNW localized on the top of the W needle in order to measure the masses of SiO 2 and TiO 2 nanospheres with diameters of (350 ± 30) nm and (120 ± 10) nm and masses (26 ± 5) · 10 −15 g and (3.5 ± 0.5) × 10 −15 g, respectively. At the same time nanospheres of SiO 2 and TiO 2 were transferred from Si substrate to CNW by means of W needle of a micromanipulator…”

“…SiO2 nanospheres were attached to the CNW with a short (1 s) local FEB pulse assisted deposition of carbon at the point of contact between nanosphere and the CNW . It should be noted that during 1 s only 10 −18 g of carbon is deposited, which is five times less than the minimum detectable mass of the proposed sensor.…”

Nano‐mechanical oscillator (NMO) based on amorphous carbon nanowhisker (CNW) with nanotraps for resonant weighting of nanoparticles in range of mass (10−14–10−15) g is presented. NMO with nanotraps is fabricated on the top of tungsten tip using focused electron beam technique. For resonant weighting the gold nanospheres are captured under the exposure of an electron beam by nanotraps locate on the top of CNW. Jump of gold nanoparticle to the nanotrap and oscillations of CNW are visualized using scanning electron microscope (SEM). The NMO amplitude‐frequency characteristics are calculated via automated numerical analysis of the sequence of SEM images obtained during the oscillations frequency sweeping. In order to calibrate the resonance mass detector based on CNW with nanotrap the gold nanosphere with diameter of (170 ± 5) nm and mass of (49.6 ± 9.2) × 10−15 g is weighed in vacuum.

Optical tweezers are widely used for manipulating nano- and micro sized particles. The presence of a special plasmon substrate can significantly affect the optical forces acting on an object. This paper discusses the possibility of experimental measuring optical plasmon forces using a mechanical resonator based on a carbon nanowhisker. A mathematical model describing the effect of optical forces on nanowhisker oscillations with an additional nanoparticle at the end is presented with taking into account the effect of surface plasmon waves on the substrate.
