Ionic- liquid polymer brushes as antifouling surface coatings

Surfaces are prone to attract pollutants which is a severe problem in (bio)medical applications. Bacteria will attach themselves to a surface upon an infection, which will ultimately form a biofilm. Biofilms are highly problematic for medical implants as the bacteria are less affected by the applied antibiotics and hence are able to spread. Preventing biofilm formation will enable less usage of antibiotics leading to less resistance.

The aim is to develop a broadly applicable surface coating based on the concept of liquid surfaces using polymer brush technology combined with ionic-liquid polymers. The combination of liquid properties with surface-tethered polymer brushes enable the liquid surface to be slippery. This prevents any contaminant including bacteria to attach themselves to the surface. We use these surfaces as well as conventional brushes to investigate yeast-bacteria interactions to elucidate complex behaviour of mixed populations. The project is medically driven but with outreaches to the food industry.
