Abstract:
Quantitative studies of material properties and interfaces using the atomic force microscope (AFM) have
important applications in engineering, biotechnology and chemistry. Emerging studies require an estimate of the
stiffness of the probe so that the forces exerted on a sample can be determined from the measured
displacements. Numerous methods for determining the spring constant of AFM cantilevers have been proposed,
yet none accounts for the effect of the mass of the probe tip on the calibration procedure. This work
