The adhesion between a micro/nano-object and a microgripper end-effector is an important problem in micromanipulation. Canceling or reducing this force is a great challenge. This force is directly linked to the surface chemical structure of the object and the gripper. We propose to predict this force between a structuring surface and a micro-object with a multisphere van der Waals force model. The surface was structured by polystyrene latex particles (PS particles) with radii from 35 to 2000 nm. The model was compared with experimental pull-off force measurements performed by AFM with different natures of spheres materials glued on the tipless. A wide range of applications, In the field of telecommunications, bioengineering, and more generaly speaking MEMS can be envisaged for these substrates.
