dc.description.abstractIn this contribution I will present recent results on the enhanced photo-activity yield and bio-response of crystalline nanospikes created on rutile TiO2 single crystals and thermally grown polycrystalline rutile TiO2 surfaces. The method for generating these nanospikes is based on high energy ion beam irradiation and a subsequent chemical HF etching [1], which previously has been employed for modifying the TiO2 response to biomolecules [2]. Although the created nanospikes preserved the rutile structure, they contain damage in their crystal lattice. We have experimentally studied the structural, compositional, and optical variations of the nanostructures and relate this to changes in efficiency of UV photo-degradation of organic molecules [3,4] and nanostructure recognition of two types of cells: human mesenchymal stem cells[5] and aortic vascular smooth muscle cells. The present work highlights the complexity involved in understanding the photoactivity and bioresponse of nanostructures, where many factors ¿ optics, reactivity and effective exposed surface ¿ have to be taken into account when comparing the efficiency of TiO2 nanostructures with flat surfaces.es_ES
