Self-assembly of colloidal particles on different surfaces

The self-assembly process of colloidal particles on different surfaces: mica, glass, Ag and Au thin films is presented. The quality of the self-assembled monolayers is dependent on the solid concentration of colloidal particles, roughness of the surface, contact angle of the water droplet and chemically produced surface charges on the substrate. The surfaces parameters where analyzed by contact angle measurements and atomic force microscopy (AFM). The final deposition was characterized by optical and scanning electron microscopy (SEM).
