Description
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 Microbial Adhesion research group-NANBIOSIS ICTS U16 Surface Characterization and Calorimetry Unit of the University of Extremadura (AM-UEX)-, belonging to the CIBER-BBN, led by Maria Luisa González, is searching in natural products, specifically in propolis, compounds with antimicrobial activity to help fight infections associated with biomaterials.Medical devices have greatly improved healthcare. But biofilm-associated infections related to the use of these devices are a major clinical concern. Biofilms are understood as bacterial communities that adhere to the surface of the devices and are embedded in a polymeric matrix that they themselves produce. This supracellular social organization arises as a survival strategy[...]

Today February 11 is the International Day of Women and Girls in Science, a day to raise awareness of the gender gap in science and technology. According to the United Nations, while yet women and girls continue to be excluded from participating fully in science, science and gender equality are vital to achieve the internationally agreed development goals, including the 2030 Agenda for Sustainable Development. Thus, in recent years, the international community has made a great effort to inspire and promote the participation of women and girls in science. NANBIOSIS wants to acknowledge the efforts made by scientific women who struggle every day to contribut[...]

Researchers of Nanbiosis U16 Surface Characterization and Calorimetry Unit of CIBER-BBN and University of Extremadura in Badajoz, are the authors of an article published by Materials Chemistry and Physics, The researchers studied the surface chemical information of thirteen used catheters that had remained in patients for two months, using the XPS technique with the purpose of this communication is to report.Compositional changes in relation to unused catheters provided information on the degree of the chemical degradation suffered. ATR-IR added information on the chemical characterization of the samplesand Scanning Electron Microscopy (SEM) analysis will advise on topographical changes. The XPS techniqu[...]
