Nanomanufacturing of titania interfaces with controlled structural and functional properties by supersonic cluster beam deposition

摘要

Great emphasis is placed on the development of integrated approaches for thesynthesis and the characterization of ad hoc nanostructured platforms, to beused as templates with controlled morphology and chemical properties for theinvestigation of specific phenomena of great relevance for technologicalapplications in interdisciplinary fields such as biotechnology, medicine andadvanced materials. Here we discuss the crucial role and the advantages of thinfilm deposition strategies based on cluster-assembling from supersonic clusterbeams. We select cluster-assembled nanostructured titania (ns-TiO2) as a casestudy to demonstrate that accurate control over morphological parameters can beroutinely achieved, and consequently over several relevant interfacialproperties and phenomena, like surface charging in a liquid electrolyte, andproteins and nanoparticles adsorption.
