A compressive force F is applied by an adhesive sphere on an elastic half-space representing the surface of a cell. Our goal is to estimate to if Hertz model could still be used to establish the relationship between the force F and the indentation d, or if a model taking into account adhesion is unavoidable.

Dimitriadis et al. (Dimitriadis et al., Biophysical Journal 82(5) 2798–2810) have established a correction to the Hertz model for the indentation of a thin layer of thickness h and Young's modulus E, by a sphere R pressed with a force F. For an incompressible layer bonded to its substrate, the relationship between the compressive force Fand the indentation dis : ER1/2d3/2[1 + 1.133x + 1.283x2 +0.769x3 + 0.0975x4], Rd where x = aperta h Q10.
