Abstract
A method for increasing adhesion between a substrate and a polymeric imprintable material during an imprinting procedure. The method includes chemically bonding a plurality of molecules to a surface of a substrate to form a self-assembled monolayer thereon. A monomer is copolymerized with the self-assembled monolayer to form a polymeric imprintable material that is chemically bonded to the self-assembled monolayer. Adhesion between the polymeric imprintable material and the substrate is substantially increased by the self-assembled monolayer.
