- Abstract:
- A fabrication process for multifunctional surfaces is designed leading to five different functional moieties (amine,
thiol, carboxylic acid, fluoro, and methyl) being present on a single structured surface. The multifunctional surface is
created by combining UV-ozone patterning, electro-oxidative lithography, the local deposition of self-assembled
monolayers (SAMs), and surface modification schemes. Besides the characterization with conventional surface-sensitive
techniques, the nature of the locally functionalized regions is demonstrated by self-assembly of three different probe
nanomaterials (Si nanoparticles, Au nanoparticles, and hydroxyl functionalized micelles). A versatile fabrication
approach for complex surfaces with addressable functionalities can be created, and it was possible to integrate five
different functionalized areas on one substrate.
