The influence of capillary effect on atomic force microscopy measurements

Side chain effects in the packing structure and stiffness of redox-responsive ferrocene-containing polymer brushes

“…Fig. 4 shows the histograms and distributions of E app in DI water (to avoid the high adherence between AFM tip and polymer brush due to the capillary force [56][57][58][59], we performed the measurements in DI water instead of air) and the results are summarized in Table 1. E app values were estimated in a range of 0.45-0.18 MPa in DI water.…”

Influence of Relative Humidity on Interparticle Capillary Adhesion

“…It is therefore crucial to investigate the influence of humidity-dependent capillary force in, for instance, food processing, pharmaceutical mixtures, powder handling, aerosol suspension, and biomaterial dehydration . Such studies are in fact fundamental to estimate the performance and lifespan of micro-/nano-electromechanical devices and nanostructures …”

“…8 Such studies are in fact fundamental to estimate the performance and lifespan of micro-/nano-electromechanical devices and nanostructures. 9 A number of advanced instruments are capable of quantifying adhesion, namely, surface force apparatus (SFA), 10 force feedback microscope, 11 force traction device, 12 and atomic force microscope. 13,14 AFM is by far the most prevailing technique to investigate nano-to pico-Newton range forces with nanometer actuation displacement and is apt to measure the "pull-off" force or the critical tensile load to detach two adhered bodies such as a particle on a substrate.…”

Nanometer-precision non-local deformation reconstruction using nanodiamond sensing

“…It largely depends on the conditions of the indentation, such as the type of indenter, the indentation speed, the type of liquid employed, the humidity, etc. 15,16 . If soft matter or biological systems are studied, the viscosity of the samples also plays a role.…”
