Lithography of nanoparticle based inks

This invention describes a special kind of ink made from tiny metal particles, like silver, suspended in a mix of water and other liquids. This ink is carefully designed to dry slowly and have just the right thickness for drawing extremely fine patterns on surfaces using specialized tools, such as a tiny pen-like device. The goal is to create very small, continuous lines and dots that can conduct electricity, useful for things like repairing electronic surfaces.
