The purpose of this Unit is to give support for the analysis of surface composition to researchers. This facility allows a broad knowledge about the chemistry of surfaces by the combination of the information of elements presents and their coordination state, given by the XPS technique, and the molecular structure of surface provided by the ToF-SIMs equipment. Its capabilities permit to work with extended and powdered solids, including those from biological origin as cells and bacteria. The characteristics of thin films on surfaces, as thickness, composition or electrical conductivity, can be also analyzed in this unit by spectroscopic ellipsometry. In addition, calorimetric analysis can be performed to test surface reactivity on powdered solids. ITC calorimetry facility is also under the Unit scheme.
Surface analysis laboratory fulfils the ISO9001:2008 (ES050823-1).
The magazine Viceversa dedicates a special article to María Luisa González, Professor of Applied Physics at the University of Extremadura and Scientific Director of Unit 16 of NANBIOSIS: Surface Characterization and Calorimetry Unit. One of her latest projects, PHYTECH, has developed a new surface for bone implants containing phytate, a natural product found in plant seeds that favours the regeneration of bone tissue and reduces the risk of infections in implants. Now, her research group is about to start a new European project with implant manufacturers in Austria and Lithuania, whose goal is to obtain a crystalline coating for titanium[...]
The Phytech project (funded by the Spanish Government through the Call INNPACTO) has recently finished with the participation of CIBER-BBN, through Unit 16 of NANBIOSIS, the University of the Balearic Islands and the companies NuMat Biomedical and Sanifit). Unit 16 of NANBIOSIS – Surface Characterization and Calorimetry, coordinated by Dr. M. Luisa Gonzalez, has conducted tests of surface composition by surface characterization techniques (XPS and ToF-SIMS) as well as the analysis microbial response of the raised surfaces in this development The results of this project have been published in the journal Applied Materials & Interfaces of the American Chemical Society.[...]
