Abstract
Described herein are compositions and methods for wetting and adhering noble metal inks to silicone substrates. The metal ink-silicone interface is modified by functionalizing the surface of noble metal nanoparticles (NPs) or nanowires (NWs), and/or the surface of silicone substrates, with a small molecule binder for thiol-noble metal bonding.
