Abstract: Nanoparticles with a bimetallic silver-copper (AgCu) alloy composition with ambient (room temperature) sintering properties. The bimetallic alloy is formulated with nanoparticles which are contained in a stable nanoink or nanopaste. The nanoink or nanopaste can be printed on paper and other substrates and be sintered under room temperatures. A method of creating the AgCu composition is also provided.
