Robust Strategies for Automated AFM Force Curve Analysis—I. Non-adhesive Indentation of Soft, Inhomogeneous Materials

Abstract: The atomic force microscope (AFM) has found wide applicability as a nanoindentation tool to measure local elastic properties of soft materials. An automated approach to the processing of AFM indentation data, namely, the extraction of Young's modulus, is essential to realizing the high-throughput potential of the instrument as an elasticity probe for typical soft materials that exhibit inhomogeneity at microscopic scales. This paper focuses on Hertzian analysis techniques, which are applicable to linear elasti… Show more

“…In this model, it is assumed that the indenter tip is not deformable and thus it does not change during the measurement and that the Young's modulus for the indenter tip is much larger than the Young's modulus for the sample. The Hertz model for a sharp cone of tip angle 2c yields to the following equa-tion for the load force, F as a function of the indentation depth, ı (Bulychev, Alekhin, Shorshorov, Ternovskii, & Shnyrev, 1975;Ferencz, Sanchez, Blumich, & Herrmann, 2012;Lin, Dimitriadis, & Horkay, 2007),…”
