We present the results of mesoscopic Dissipative Particle Dynamics (DPD) simulations concerning monolayers with varying length in contact with an explicit solvent. Our results indicate different solvent interface concentrations for varying monolayer thicknesses. Additionally we have calculated the free binding energy for a test particle. Our results demonstrate that the test particle is stronger adsorped at thinner monolayers due to a decreased solvent content and a higher monomer density at the interfacial region. The numerical findings are in good agreement with experimental observations.
