Measuring Mechanical and Adhesive Properties of Single Cells Using an Atomic Force Microscope

Methods Mol Biol. 2021:2294:81-92. doi: 10.1007/978-1-0716-1350-4_6.

Abstract

Atomic force microscopy allows the determination of both mechanical and adhesive properties of living single cells and generation of high-resolution surface images. Here, we describe a method to determine the Young's modulus of a cell and adhesion between a coated cantilever and a cell, as well as an overview of the analysis of the data obtained. Additionally, we point out typical and important pitfalls during the measurement and analysis.

Keywords: AFM; Adhesion; Atomic force microscopy; Biomechanical properties; Biomechanics; Elasticity; Young’s modulus.
