The Atomic Force Microscope (AFM) is one of the key instruments in nanotechnology, enabling precise manipulation and positioning of nanoparticles. In this context, the second phase of two-dimensional nanomanipulation, corresponding to the stable motion of the particle after the onset of displacement, plays a crucial role in optimizing the process. This study analyzes the influence of geometrical and mechanical parameters on the manipulation force using the Design of Experiments (DOE) approach. The novelty lies in the development of a contact model based on the (JKR) theory and the quantitative analysis of the second phase of nanomanipulation through DOE. A multivariable regression model was derived, and the statistical indicators of fit (R² = 89.99%) confirmed the model’s validity. The results revealed that geometrical parameters have the most significant impact on force variations. Specifically, the tip radius (62%) and particle radius (25%) exhibited the strongest effects in reducing manipulation force. The cantilever height showed a minor influence (12%). In contrast, the elastic modulus and Poisson’s ratio had negligible effects.
