Abstract:
1. A surface modified substrate, comprising: (a) a substrate having a surface, (b) a monolayer consisting of nanoscale inorganic oxide particles disposed directly on at least a portion of the surface of the substrate, said layer of nanoscale inorganic oxide particles comprising sites that bear an electric charge of a first polarity, the monolayer of nanoscale inorganic particles has a first surface in contact with the surface of the substrate and a second surface oriented away from the surface of the substrate; and (c) a monolayer of a polymer disposed on and adhered to a least a portion of the monolayer of nanoscale inorganic oxide particles, said monolayer of copolymer comprising sites that bear an electric charge of a second polarity, wherein the second polarity is the opposite of the first polarity, the monolayer of polymer has a first surface in contact with the second surface of the layer of nanoscale inorganic oxide particles and a second surface oriented away from the layer of nanoscale inorganic oxide particles.
