(a) Illustration of the chemical forces between the inks. A small gap can be accomplished with any ink pairing with opposing chemistries, not just silver nanoparticle solutions. (b) Two parallel lines forming a chemical gap. The lines are electrically isolated. (c) A zoomed in image of an average chemical gap. Results like this were observed across multiple devices. (d) SEM photograph taken at 16880× magnification of the smallest observed electrically isolated gap.
