In this thesis we deal with the analysis and measurement of dispersive surface forces, specifically the Casimir force. Applying Lifshitz theory makes it possible to take into account the material optical property and consequently the obtained results are more realistic. We used contact mode atomic force microscopy for measuring the force experimentally. We show how we can tailor the Casimir force with changing optical property by using different materials including gold (Au), Phase-Change-Materials (PCMs) in amorphous and crystalline state, and Silicon Carbide (SiC). The research presented in this thesis is essential for studying the dynamical behavior of MEMS/NEMS and its design, where surface forces are playing a key role. The combined experimental and theoretical progress has allowed researchers to design geometries and materials that may lead to new regimes of operation for nano/micromechanical devices and may also provide new ways to combat unwanted interactions such as ‘stiction’ between moving parts.
