Throughout the year 2014 our research group has conducted its investigation on surface modifications and processes in order to achieve a better response against bacterial colonization . It is to mention those contributions related to metal prosthetics materials addressed to both, the behavior of its passive layer in anaerobic conditions and the modification of their electrochemical properties, due the latter to a bacterial biofilm growth on their surface . Also, new surface modifications have been tested to decrease microbial colonization on metal materials; these tasks were carried out in collaboration with other CIBER groups to assess the biocompatibility of these modifications against various cell lines . In a different issue related to the topic, we were particularly involved in the study of those degradable materials able to release metal ions into the surrounding medium, since it can represent an advantage against infections on these materials . Additional studies, at a fundamental level, were focus on the relationship between surface textural and morphological aspects and protein adsorption, mainly on the unfolding of proteins .
With regards to the translation area we have collaborated with various companies . These works were in the field of microbial contamination and the thorough analysis of modified surfaces . These activities were performed either by direct agreements with our group or through the Surface Characterization nodule of the Equipment Platform . Finally, we should highlight the collaboration with the Maxillofacial Surgery Unit of the Infanta Cristina University Hospital in Badajoz, particularly on the damage and alterations of different osteosynthesis elements after explantation .
