The applicability, versatility and even certain properties of nanoparticles are enhanced through either their self-assembly or deposition on platforms (glass, beads, cellulose paper, hydrogels, polymer films, etc.). Following different approaches based on layer-by-layer deposition, solvent evaporation induced forces, hydrophobic or capilary forces, among others, we have fabricated a wide variety of nanostructured materials for multiple applications.
