TESCAN FIB-SEM LYRA3: Understanding interactions between bacteria genre and surface properties
In the present work, an evaluation, comparison, and discussion of flat, nanostructured, and rough Ti6Al4V surfaces on the behavior of bacterial adhesion has been – for the first time – carried out. The materials were characterized (among other techniques) by means of scanning electron microscopy and energy dispersive X-ray spectroscopy (EDX) with the TESCAN FIB-SEM LYRA3 microscope. The results of this work open up a novel pathway for the investigation and comparison of the effects of Gram-positive and Gram-negative cell walls on the behavior of biocompatible surfaces for the understanding of the implant-related infections.
