Resumen del contexto y de los objetivos generales del proyecto

Smart interfaces, i.e. interfaces that change their properties on external triggers, such as temperature or electrode potential are a promising technology that can be applied in materials science, biotechnology or medicine. In this project a novel approach to realize such smart interfaces is investigated by applying a group of biologically abundant molecules, the coiled-coil peptides. The novel interface will allow for new applications that foster biotechnological research and technological progress.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

(I) The adsorption of coiled-coil peptides to hydropphilic-hydrophobic switchable germanium interfaces has been studied. The results indicate a completely different adsorption mechanism for the studied peptides. A manuscript for dissemination is in preparation.
(II) Coiled-coil binding to mixed SAMs has been studied. The studied systems show no switchable behaviour. For future work a different binding mechanism must be targeted. A manuscript for dissemination is in preparation.

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

Smart interfaces based on coiled-coils open fascinating possibilities for applications. However, a realization is more difficult than anticipated. Difficulties arise from the interplay between peptide-peptide and peptide-interface interactions. During preparation these interactions affect significantly, the properties of the final interface. The project results provide an insight into these factors and their effects and build a base for further research in this direction.

Basic design and targeted working principle of a coiled-coil based smart interface.
