Abstract
We present a general procedure for determining the zero of separation in colloid probe Atomic Force Microscopy (AFM) measurements on deformable particles. This method consists of shifting the data to coincide with the known rigid body interaction at large separations where the force is weak and the deformation is negligible. The technique is generally applicable to double layer interactions where the surface potential has been independently measured.
