My research aims to design biomaterials and improve existing ones in order to avoid bacterial colonisation processes on their surfaces, thus contributing to the fight against infections associated with the use of implants. The study of both the surface of the biomaterials and the microorganisms is fundamental to this path. To this end, I work with different physicochemical characterisation techniques to predict the biomaterial-bacteria adhesive behaviour and thus be able to draw up more effective strategies to combat infection.
