• stiffness of such a cantilever has about the same order of magnitude as that of a tuning fork, its resonance frequency is almost two orders of magnitude higher. According to Equation 1 and Equation 2, cantilever sensors have thermal and deflection noise advantages of, respectively, about one and two orders

• Dynamic-mode cantilever sensors are used for many different applications which include the detection of smallest masses [1][2], in situ observation of the growth of biological films [3], detection of trace analytes in gases (”artificial nose”) [4] and the investigation of properties of novel (nano

• )materials by scanning probe methods or magnetometry [5][6][7]. In contrast to static-mode operation, where the static bending of cantilever sensors is used as a measurement signal, the dynamic mode is based on exciting the beam to vibrations and monitoring its amplitude, resonance frequency and phase shift

A microfluidic flow tool has been previously employed in connection with cantilever spring constant determination [27][28][29][30], and it was shown that forces due to the flow from a microfluidic channel

We demonstrate that a microfluidic flow can provide accurate forces and allows the static spring constant of cantilever sensors to be determined with high precision and without any contact between the sensor and a surface. We show the applicability of the method for
