Abstract
A force sensing probe () for sensing snap-in and/or pull-off force of a liquid droplet () brought into and/or separated from contact with a hydrophobic sample surface (), respectively, comprises: a sensing tip (); a sensor element () connected to the sensing tip, capable of sensing sub-micronewton forces acting on the sensing tip in a measurement direction; and a droplet holding plate () having a first main surface () and a hydrophilic second main surface () connected via a peripheral edge surface (), and being attached via the first main surface to the sensing tip () perpendicularly relative to the measurement direction for receiving and holding a liquid droplet () as attached to the second main surface; the droplet holding plate comprising an electrically conductive surface layer (), the first and the second main surfaces and the peripheral edge surface being defined by the surface layer.
