Patent ID: 7824734

Claim:
A method of applying a layer or pattern of metal on a substrate, the method comprising: providing a target substrate, immobilizing a layer of polymeric material on the target substrate, applying and immobilizing a layer or pattern of metal on the layer of polymeric material on the target substrate using a stamp onto which the layer or pattern of metal has previously been applied, by bringing the stamp into conformal contact with the target substrate, wherein the layer of polymeric material includes a polymer that has a flexible polymer chain including a poly(ethylene glycol) (PEG) having approximately 60-70 ethylene glycol units, the polymer including a proximal end and a distal end having a functional group, wherein the layer of polymeric material is covalently linked to the target substrate at the proximal end, and wherein the functional group allows the immobilizing of the layer or pattern of metal on the layer of polymeric material.
