Abstract
A surface modified substrate includes a substrate having a surface, a layer of nanoscale inorganic oxide particles disposed on at least a portion of the surface of the substrate, said layer of nanoscale inorganic oxide particles comprising sites bearing an electric charge of a first polarity, and a monolayer of a polymer disposed on a least a portion of the layer of nanoscale inorganic oxide particles, said monolayer of polymer comprising sites bearing an electric charge of a second polarity, wherein the second polarity is the opposite of the first polarity.
