The TEXTIR project aims to design multifunctional textured surfaces through a combination of nitrogen jet particle projection texturing and functionalisation by biobased polymers of metal materials for biofilm control in biotechnological and industrial applications. This project has two components aimed at exploiting the different facets of bacterial biofilm control. The first part of this project is to texture and functionalise the surfaces of artificial prosthetic materials used in reconstructive surgery to give them new properties, in particular (i) osteoconductive/osteoinductive activity, (ii) antibacterial and (iii) inhibiting bacterial internalisation processes. The second part aims to texture and functionalise conductive surfaces in order to exploit their bio-electrocatalytic properties in the presence of biological objects with the aim of developing a laboratory-scale pilot enabling the production, control of purity and chirality of molecules of interest to the pharmaceutical industry. Thus, the materials developed in this component will be optimised for i) the electrical connection of microbes and enzymes allowing (ii) the controlled bio-electynthesis of molecules of interest.
