In previous studies, the cytotoxic impact of apical exposure of the same functionalized nanoparticles to the same epithelial cell line (MDCK II) was presented [18] and the cellular uptake was quantified [20].

• often heterogeneous in their chemical composition, functionalized nanoparticles provide good model systems to study and tune the mobility of nano-objects on these substrates. As a next step, the role of the hydrohilicity and hydrophobicity of the functional grafting on spherical Au nanoparticles is
