A Substrate-Independent Approach for Bactericidal Surfaces

Existing methods for imparting antibacterial performance to solid surfaces tend to either be substrate-specific or rely upon leaching modes of action that cause ecological damage. An alternative approach is outlined comprising plasmachemical functionalization of solid surfaces with poly(4-vinyl pyridine) moieties and their subsequent activation (quaternization) with bromobutane to yield bactericidal activity, These bioactive surfaces can be applied to a host of different substrate materials and are easily regenerated by rinsing in water.
