- In this novel paper, using the principle of slow-time varying function theory, a new numerical equation is developed to reconstruct the nanoscale interaction force between AFM cantilever and sample. This important method will partially solve a long-term challenge to recover the force and subsequently the materials properties from amplitude and phase-signals of ‘tapping mode AFM’ during spectroscopy in both air and liquid environment for different indentation lengths independent of sample stiffness. Using the proposed method of this paper, quantitative 3D-mapping of a solid-liquid interface using tapping mode AFM is possible: ACS Nano 12 (12) (2018), Nature Communications 7, 12164 (2016).
