Schematic of one cycle of force spectroscopy measurement.
Force-distance curve measured in air.
Example of force-distance retract curves: low amplitude adhesion force (a) and the base line distortion (b).
Broken line curve used to model force-distance curves.
Force curve patterns with indicated adhesion forces: (a) with baseline drift and (b) without baseline drift.
Illustration of inefficiency of the standard methods of snap-out point detections for the FNR = 2: (a) illustration of smoothing operation (deterioration of peak amplitude in smoothed signals), (b) in the smoothed signals the remaining noise prevents us from the snap-out point detection.
