Chemistry and Patterning of Functional Surfaces
The interaction between two bodies in close proximity is strongly influenced by the chemical nature of their outmost molecular layer and the surface topography.
The adhesion force between two glued surfaces, the antiadherent properties of our cooking pan, the attachment of proteins or cells onto artificial scaffolds or
the ability of certain animals to firmly attach to and easy release from any surface are relevant examples. Chemists and material scientists join their efforts in the
development of novel approaches to control adhesion phenomena at different levels and to elucidate their implications in modern technologies.
Methods and Devices
- Preparative organic chemistry
- Surface chemistry methods: Self-assembled monolayers (SAMs), plasma activation
- Protocols for immobilisation of biomolecules onto surfaces
- Surface micro and nanopatterning methods: optical lithography, soft-lithography, hot embossing
- Surface characterisation techniques: SEM, ellipsometry, interferometry
- Characterisation of adhesion forces by peel-off tests
Recent highlights
- Complex surface compositions for controlled and functional immobilisation of biomolecules
- Hierarchical and 3D micro and nanopatterning methods for fabrication of bioinspired adhesives: first experimental evidence for the "contact splitting effect" in the micron scale
