Antibacterial and antifungal coatings

During the last decades, silver metal nanoparticles have spurred a lot of interest due to their biocidal properties. Among noble metals, Ag metal nanoparticles possess the most efficient biocidal properties with a very broad bactericidal and fungicidal activity spectrum. In this project we study the antibacterial and antifungal properties or Ag nanoparticles synthesized by sol-gel methods. The first approach is to acquire sufficient knowledge on surfactant free Ag nanoparticles to better understand the biocidal properties of the Ag nanoparticles synthesized using plants extracts. We are presently developing a cost effective method based on plant extracts utilization that should enable the development of antibacterial and more particularly antifungal coating. The aim is to apply such non-toxic biocidal coatings to applications like green housing using ecological materials and paints for hospital.
