Fig. 3: Tuning spectra of a FluidFM micropipette cantilever in air and water (channel filled with water), measured with a Nanosurf Drive AFM.
From: Hydrodynamic function and spring constant calibration of FluidFM micropipette cantilevers

The spectra were obtained with a thermal tuning and b the company’s CleanDrive Technology. In the latter case, the amplitude of the spectrum measured in water was multiplied by 5 for the sake of comparability. The spectra correspond with the data presented in Table 1
