It is well-known that the Interparticle interactions between adsorbates and surface of an adsorbent can affect the surface morphology. One of the consequences of this issue is that the resonant frequency of a nanoscale resonator can be changed due to adsorption. In this study we have chosen a cantilever-based nanoscale mass-sensor with a single nanoparticle at its tip. Using the classical...

A simplified Doppler frequency shift (DFS) measurement approach based on Serrodyne optical translation is reported. sawtooth wave with high amplitude sent to one phase modulation arm of a Mach–Zehnder modulator in conjunction the transmitted signal implement translation, as well frequency-shifted carrier. The echo applied other modulator. lower first-order sidebands from are selected by an band...
