Mechanics of eukaryotic cells at the nanoscale is a challenging problem due to complexity of cells. Besides fundamental interest, such measurements are important because it has been demonstrated that the elastic modulus of cells can correlate with various diseases and even aging. Atomic force microscopy (AFM) is the technique of use. At the same time, there is a lot of confusion in the process of measurements of the elastic modulus of cells. In the talk, author will present the modern overview of the topic, describe step-by-step how to do the measurements of the elastic modulus in quantitative manner that is independent of the particular microscope, AFM probe, and mechanical model.
